It is a matter of great satisfaction that people are now becoming aware of environment and ecology. Everyone is talking about the grave environmental crisis towards which India and the world are heading. Environment has been broadly defined as whatever environs or encompasses, especially one’s surroundings, which affect the life and development of an organism. It simpler terms, our environment is our surroundings including both living and non-living components of it. These components of the environment constitute the environmental assets or resources. It is, therefore, necessary that every environmental planning should imply planned exploitation, utilisation, conservation and sustainable development of these assets or resources to achieve certain short-term and long-term objectives. The short-term objectives may include meeting the immediate needs for food, fodder and fuel as well as the need for communications and shelter of a growing human and animal population in a sustainable manner, which cause minimum possible depletion in and damage to our environmental resource base. The basic long-term objective should be to conserve, protect and develop the environmental resource base so that the genetic diversity is preserved and the regeneration of renewable resources keep pace with their inevitable loos or degradation inherent in the process of their exploitation and use to fulfill the needs of the society.
The concept of environment is relatively of a recent idea to the world, if not to India. It all started only when a Dutch journalist was alarmed and protested at the discharge of poisonous fluid into North Sea which killed thousands of marine life. Within two years, this protest prompted one hundred twenty-five countries to meet for a dialogue to find a way out from the impending destruction of environment and wild life all over the world. However, the concept of environment has been in vogue in the Indian collective thinking right from the Vedic period/ Rabindranath Tagore also expressed anguish over sacrifice of living animals and condemned the ruthless destruction of forests and its effect on human society. He did warn that the deleterious effect of deforestation, industrialisation and mass destruction of living species would engulf the entire human race one day.
What are you going to do this weekend?
I'm going to go to Gangneung with my family. We're going to visit Dano Festival. We can wear hanbok and eat delicious food there. I can't wait!
DNA stands for De oxy ribo nucleic acid.
DNA is located in the nucleus of the cell. DNA codes for the appearance of an organism and codes for how an organism functions.
DNAs structure was discovered in 1953. The structure of DNA is a double helix. Each chromosome is 1 long DNA strand wrapped up around a protein. Humans have 46 chromosomes with neutrons in every cell.
46 chromosomes are paired into 23 chromosome pairs.
23 chromosomes are from the mother (23 in an egg)
23 chromosomes are from the father (23 in sperm)
When an egg is fertilised it becomes 46 chromosomes again.
The Watson crick DNA model is the whole strand of DNA is made of smaller groups called nucleotides. Nucleotides are made of phosphate groups, sugar and nitrogen-rich base.
22 pairs of human chromosomes and pair 23 is the sex chromosome.
Females have two copies of X - XX
Males have one X and one Y - XY
Genes are sections of DNA that code for particular proteins, a group of genes will code for a function or characteristic. eg. hair colour.
The four nitrogen-rich bases are A, C , G and T
When cells replicate they are making copies of your DNA.
This process is called mitosis: One cell (parent cell) divides into 2 identical daughter cells. Mitosis is used: for growth and repair, asexual reproduction and tissue regeneration.
Meiosis is used for sexual reproduction eg. sperm and egg or pollen and egg.
2 gametes join to form a fertilised egg, the gametes only have one copy of each chromosome. The human haploid number is 23. The diploid number is 46 (two copies of each chromosome)
Inheritance is when characteristics are passed on from parent to offspring. One of the patterns of inheritance is dominant and recessive.
The gene for a pea flower colour is carried on one pair of chromosomes. The gene comes in two variations called alleles. One allele is red and one is white. One allele will be dominant and the other will be recessive. In this case, the red allele is the dominant allele. This means if a pea has both alleles, the pea will look red.
The gene for a pea flower colour is carried on one pair of chromosomes.
If parent 1 has RR (two red alleles) and parent 2 rr (two white alleles) the off all have Rr. The recessive allele is the same letter as the dominant just in lowercase. eg. r = recessive and R = dominant
If an organism has two different alleles it is heterozygous. If it has two of the same alleles it is homozygous.
A child with genotype Rr would show the phenotype of being red because it carries at least one dominant allele. A child with genotype rr would show the phenotype of being white as it does not carry any dominant alleles.
Genotype is the actual allele code an organism has (RR or rr or Rr)
Phenotype is the appearance of the organism in relation to that characteristic.
Punnet squares are used to determine the probability of offspring inheriting particular traits.
Co-dominant inheritance is when both alleles for the trait are expressed in an organism. eg. a pea flower has red or white alleles, if the pea has both alleles it will be pink the allele would be named with different capital letters eg. W & R
Sex-linked inheritance is when some genes are located on the sex chromosome (X or Y) eg. red-green colour blindness
Chromosomal abnormalities are when mistakes happen in the replicating of DNA. If this happens during miosis making gametes the mistake is passed onto the offspring.
Having an extra copy of a chromosome results in chromosomal abnormalities eg. down syndrome (extra copy of 21)
Mutations happen when there are mistakes in the genetic code. eg. the base is replaced with the wrong/different thing. Mutation causes the gene to stop being copied or there is an extra or deleted base. This causes all the information/codes to be jumbled.
Evolution is defined as the change in the inherited traits of a population of organisms through generations.
Generational changes lead to a species changing into a different species or subspecies.
Species can breed with other organisms in the same species to produce fertile offspring. Sometimes two very similar species can interbreed, their offspring are called hybrids. Hybrids are infertile and have health problems. Some hybrids are stronger/better.
Species can breed with other organisms in the same species to produce fertile offspring. Sometimes two very similar species can interbreed, their offspring are called hybrids. Hybrids are infertile and have health problems. Some hybrids are stronger/better.
Natural selection is the current theory of how species evolve into other species. For natural selection to occur, the population must have variety and a selective agent. Eg. and owl on a population of mice. The organisms with the best survival traits are most likely to survive and breed.
Future generations are more likely to have a higher % of having that trait. The population's genetic makeup starts shifting from the original population.
The peppered moth theory suggests that the decline in the population of the peppered moth was due to the loss of camouflage. Kettlewell noticed black moths survived better in polluted/darker areas and light moths survived in lighter areas.
Bacteria that are resistant to antibiotics are more likely to survive and reproduce. If a species is resistant to all antibiotics, it will be able to reproduce and spread to other species. Species that reproduce asexually are exact clones, meaning if they aren't resistant to the bacteria it will seriously affect their population.
A gene pool is the total number of genes of every individual in an interbreeding population.
The bottleneck effect is when a population's genetic diversity dramatically reduces from an ecological crisis. This leaves limited genetic diversity for the few survivors.
Genetic drift is the random change in allele frequencies in a population due to chance.
Speciation is the process by which one species splits into two or more separate species. 3 steps: Variation, isolation and selection
Title: The Importance of Environmental Protection and Sustainable Development Introduction: The Earth is our home, a precious and fragile ecosystem that sustains all life forms. However, human activities such as industrialization, deforestation, and pollution have placed immense pressure on the environment, threatening its delicate balance. In this essay, we will explore the critical importance of environmental protection and sustainable development in ensuring the well-being of present and future generations. Environmental Protection: Environmental protection is essential for safeguarding the natural resources and ecosystems that support life on Earth. From clean air and water to fertile soil and biodiversity, the environment provides invaluable services that are vital for human health, food security, and economic prosperity. By protecting and preserving natural habitats, we can maintain ecological stability, mitigate climate change, and prevent the loss of biodiversity. Furthermore, environmental protection is crucial for ensuring social equity and environmental justice. Environmental degradation disproportionately affects marginalized communities, exacerbating poverty, health disparities, and social inequality. By advocating for environmental justice and equitable access to resources, we can create a more just and sustainable society for all. Sustainable Development: Sustainable development seeks to meet the needs of the present without compromising the ability of future generations to meet their own needs. It recognizes the interdependence of economic, social, and environmental factors and aims to promote balanced and inclusive development that respects planetary boundaries. Sustainable development requires adopting holistic approaches that integrate environmental, social, and economic considerations into decision-making processes.
One of the key principles of sustainable development is resource efficiency. By using resources more efficiently and reducing waste and pollution, we can minimize our environmental footprint and promote sustainable consumption and production patterns. Renewable energy sources, such as solar and wind power, offer cleaner and more sustainable alternatives to fossil fuels, helping to mitigate climate change and reduce our reliance on finite resources. Moreover, sustainable development emphasizes social equity and inclusion, ensuring that development benefits are shared equitably among all members of society. It seeks to address poverty, inequality, and social exclusion while promoting human rights, gender equality, and social cohesion. By investing in education, healthcare, and social infrastructure, we can create more resilient and inclusive communities that are better equipped to face the challenges of the future. Conclusion: Environmental protection and sustainable development are not only moral imperatives but also essential for ensuring the long-term survival and well-being of humanity. By safeguarding the environment, we can protect the natural resources and ecosystems that sustain life on Earth. By embracing sustainable development, we can create a more equitable, prosperous, and resilient world for present and future generations. It is imperative that we work together to promote environmental protection and sustainable development, recognizing that our actions today will shape the future of our planet for generations to come.

Traditionally, professional expertise has been judged by length of experience, reputation, and perceived mastery of knowledge and skill. Unfortunately, recent research demonstrates only a weak relationship between these indicators of expertise and actual observed performance.
In fact, observed performance does not necessarily correlate with greater professional experience. Expert performance can, however, be traced to active engagement in deliberate practice DP, where training (often designed and arranged by their teachers and coaches) is focused on improving particular tasks.
DP also involves the provision of immediate feedback, time for problem-solving and evaluation, and opportunities for repeated performance to refine behavior.
In this article, we draw upon the principles of DP established in other domains, such as chess, music, typing, and sports to provide insight into developing expert performance in medicine.
Psychedelics are a broad class of drugs defined by their ability to induce an altered state of consciousness. These drugs have been used for millennia in both spiritual and medicinal contexts, and a number of recent clinical successes have spurred a renewed interest in developing psychedelic therapies.
ক্রিকেট বিশ্বের প্রথম ম্যাচ খেলেছে কোন দুটি দল? আরেকটু সহজ করে বললে কোন দল প্রথম আন্তর্জাতিক ক্রিকেট ম্যাচ খেলেছে? প্রথম প্রশ্নের উত্তর হয়তো কঠিন। তবে দ্বিতীয়টি বেশ সহজ। দ্বিতীয়টির উত্তর ১৮৭৭ সালে মেলবোর্নে প্রথম টেস্ট খেলেছিল অস্ট্রেলিয়া ও ইংল্যান্ড। আপনি কি জানেন, এর চেয়ে পুরনো প্রতিদ্বন্দ্বিতামূলক ক্রিকেট ম্যাচের রেকর্ড রয়েছে। ১৮৪৪ সালে যুক্তরাষ্ট্র ও কানাডা তিন দিনের ম্যাচ খেলেছিল। জিতেছিল কানাডা। ওই ম্যাচটির পর দল দুটি আর সেভাবে ক্রিকেট খেলেনি। মজেছে বাস্কেটবল, সকার, অ্যাথলেটিকস, সাঁতার, বেসবল নিয়ে। অবশ্য দল দুটি এখন ক্রিকেট খেলছে না, এমন নয়। খেলছে অভিবাসীদের গড়া দল নিয়ে। দুই দল সেই ম্যাচের প্রায় ১৮০ বছর পর পুনরায় মুখোমুখি হচ্ছে। ডালাসে আজ বাংলাদেশ সময় ভোর সাড়ে ৬টায় টি-২০ বিশ্বকাপের উদ্ভোধনী ম্যাচে মুখোমুুখি হচ্ছে যুক্তরাষ্ট্র ও কানাডা। পত্রিকা হাতে পাওয়ার পর অনেকে ম্যাচটির ফলও জেনে যাবেন। দেশ দুটি এবারই প্রথম ২০ ওভারের বিশ্বকাপ খেলছে। যুক্তরাষ্ট্র খেলছে ওয়েস্ট ইন্ডিজের সহযোগী আয়োজক হিসেবে। কানাডা খেলছে বাছাইপর্ব টপকে। একই দিন রাত সাড়ে ৮টায় ক্যারিবীয় দ্বীপপুঞ্জের অনিন্দ্যসুন্দর শহর গায়ানায় মুখোমুখি হবে ২০১২ ও ২০১৬ সালের টি-২০ বিশ্ব চ্যাম্পিয়ন ওয়েস্ট ইন্ডিজ ও পাপুয়া নিউ গিনি। এবারই প্রথম টি-২০ বিশ্বকাপে ২০টি দল খেলছে। বাংলাদেশ প্রথম থেকে টানা নবম আসর খেলছে। টাইগারদের প্রথম ম্যাচ ৮ জুন ডালাসে ২০১৪ সালের বিশ্ব চ্যাম্পিয়ন শ্রীলঙ্কার বিপক্ষে। এবারের বিশ্বকাপে প্রথমবারের যুক্তরাষ্ট্র ও কানাডা ছাড়াও প্রথমবার খেলছে আফ্রিকার দেশ উগান্ডা। দেশটি জিম্বাবুয়ে ও কেনিয়ার মতো ক্রিকেট খেলুড়ে দেশকে পেছনে ফেলে বিশ্বকাপে জায়গা নিয়ে চমকে দিয়েছে। বাংলাদেশ খেলছে নাজমুল হোসেন শান্তর নেতৃত্বে। নাজমুল এবারই প্রথম বিশ্বকাপে নেতৃত্ব দিচ্ছেন টাইগারদের। ২০ দলের বিশ্বকাপ এবার বেশকিছু রেকর্ডসকে ভেঙে ফেলার হাতছানি দিচ্ছে। দুবার করে বিশ্ব চ্যাম্পিয়ন হয়েছে ইংল্যান্ড ও ওয়েস্ট ইন্ডিজ। ইংল্যান্ড চ্যাম্পিয়ন হয়েছে ২০০৯ ও ২০২২ সালে এবং ক্যারিবীয়রা ২০১২ ও ২০২২ সালে। এবার তাদের কাতারে নাম লেখাতে পারে ভারত, পাকিস্তান, অস্ট্রেলিয়া ও শ্রীলঙ্কা। অবশ্য অস্ট্রেলিয়া চ্যাম্পিয়ন হলে এককভাবে একটি অনন্য রেকর্ডের মালিক হবে। প্রথম ও একমাত্র দল হিসেবে বিশ্ব টেস্ট চ্যাম্পিয়নশিপ, ওয়ানডে ও টি-২০ বিশ্বকাপ জয়ের রেকর্ড গড়বে। এবার ২০ দল চার গ্রুপে বিভক্ত হয়ে খেলছে। প্রতিটি গ্রুপের শীর্ষ দুটি দল সুপার এইটে দুই গ্রুপে বিভক্ত হয়ে খেলবে। দুই গ্রুপের শীর্ষ দুটি করে চার দল সেমিফাইনাল খেলবে। গ্রুপ পর্বে কোনো রিজার্ভ ডে নেই। নকআউট পর্বে রয়েছে রিজার্ভ ডে এবং প্রথম সেমিফাইনালে রিজার্ভ ডে থাকলেও দ্বিতীয় সেমিফাইনালে নেই। এ নিয়ে সমালোচিত হচ্ছে আইসিসি। ক্রিকেটের শাসক সংস্থা বলছে, ফাইনালের আগে বিরতি কম বলেই রিজার্ভ ডে রাখা হয়নি। লিগ পর্বে ম্যাচের ফল হবে কমপক্ষে ৫ ওভারের এবং নকআউট পর্বে ১০ ওভারে।
Cryptocurrency has revolutionized the financial landscape over the past decade, emerging as a significant alternative to traditional currencies. Its impact is felt worldwide, from developed nations like the United States and Canada to developing countries such as India and various African nations. Cryptocurrency’s rise offers numerous advantages, including enhanced security, anonymity, interoperability, and ease of cross-border transactions. However, alongside these opportunities come substantial challenges that must be addressed by governments and regulatory bodies to ensure its sustainable integration into the global economy.
Cryptocurrencies, beginning with Bitcoin in 2009, have transformed the way we perceive and utilize money. Initially created as a decentralized digital currency, Bitcoin introduced the concept of blockchain technology, which ensures secure and transparent transactions. This technology has been adopted by numerous other cryptocurrencies, collectively known as altcoins, which have further expanded the potential applications of digital currencies.
One of the primary advantages of cryptocurrency is its security. Transactions are secured through cryptographic techniques, making them highly resistant to fraud and hacking. The decentralized nature of blockchain technology means there is no single point of failure, enhancing overall system security. Furthermore, cryptocurrency transactions are pseudonymous, providing a degree of privacy not available with traditional banking methods. This anonymity can protect user identities, making financial activities more secure.
Interoperability and ease of cross-border transactions are other significant benefits. Cryptocurrencies can be transferred globally with minimal fees and without the need for intermediaries like banks. This can facilitate international trade and remittances, making financial services more accessible to people in regions with limited banking infrastructure. For example, in countries with high remittance costs, such as those in Sub-Saharan Africa, cryptocurrencies can offer a cheaper and faster alternative for sending money across borders.
Moreover, cryptocurrencies hold great promise for financial inclusion. In many developing countries, large segments of the population remain unbanked, lacking access to traditional financial services. Cryptocurrencies can bridge this gap by providing a decentralized financial system that is accessible to anyone with a smartphone and internet connection. This can empower individuals economically and integrate them into the global financial system, fostering economic growth and reducing poverty.
Despite these opportunities, several challenges must be addressed to ensure the safe and effective adoption of cryptocurrencies. One major issue is the lack of regulation. Cryptocurrencies operate in a largely unregulated space, which can lead to market volatility and expose users to significant financial risks. Regulatory uncertainty can deter investors and hinder the growth of the cryptocurrency market. Establishing clear regulatory frameworks is essential to provide stability and protect consumers while allowing innovation to flourish.
The anonymity of cryptocurrency transactions, while advantageous for privacy, can also be exploited for illicit activities such as money laundering, terrorist financing, and tax evasion. This poses significant challenges for law enforcement and regulatory agencies, who must find ways to monitor and control illegal activities without compromising the privacy and security benefits of cryptocurrencies. Implementing robust anti-money laundering (AML) and know-your-customer (KYC) policies is crucial to mitigate these risks.
Additionally, the volatility of cryptocurrencies presents a considerable challenge. Unlike traditional currencies, cryptocurrencies can experience drastic price fluctuations within short periods, making them unreliable as a stable store of value or medium of exchange. This volatility can hinder their adoption for everyday transactions and pose risks for investors. Developing stablecoins, which are pegged to stable assets like fiat currencies, could offer a solution to this issue.
Environmental concerns also arise with cryptocurrencies, particularly those that rely on proof-of-work (PoW) consensus mechanisms, such as Bitcoin. PoW requires significant computational power, leading to high energy consumption and a substantial carbon footprint. Transitioning to more energy-efficient consensus mechanisms, such as proof-of-stake (PoS), can help address these environmental impacts.
Furthermore, the digital divide poses a barrier to the widespread adoption of cryptocurrencies. Accessing and using cryptocurrencies requires digital literacy and reliable internet access, which are not universally available. Efforts to improve digital infrastructure and education are essential to ensure that the benefits of cryptocurrencies can be realized by all segments of society.
In conclusion, cryptocurrency presents both significant opportunities and formidable challenges. Its potential to enhance security, facilitate cross-border transactions, and promote financial inclusion is substantial. However, addressing issues related to regulation, anonymity, volatility, environmental impact, and the digital divide is crucial for its sustainable development. By balancing innovation with appropriate regulatory measures and infrastructure improvements, cryptocurrencies can become a powerful tool for economic growth and financial inclusion worldwide.
