Why are the classification systems changing every now and then?

Classification systems for living organisms are not fixed or static, but rather, they are constantly changing and evolving as our knowledge of the natural world expands.

The reasons for these changes can vary, but here are some common reasons why classification systems may change:

  1. New discoveries: As scientists discover new species and gain a better understanding of existing ones, they may need to update the classification system to reflect these new findings. For example, new DNA sequencing techniques have led to the discovery of many new species that were previously unknown.

  2. Changes in scientific understanding: As our understanding of the relationships between different organisms evolves, classification systems may need to be revised to reflect these changes. For example, the development of evolutionary theory has led to changes in how organisms are classified based on their evolutionary history.

  3. Advances in technology: Advances in technology, such as new imaging techniques and molecular biology methods, can provide new insights into the characteristics and relationships of organisms, which may require changes to the classification system.

  4. Practical considerations: Sometimes changes to the classification system are made for practical reasons, such as to make it easier to communicate information about organisms or to align with international standards.

  5. Overall, classification systems are dynamic and subject to change as new information becomes available, and scientists are constantly working to refine and improve these systems as our knowledge of the natural world grows.

Give a brief account of viruses with respect to their structure and nature of genetic material. Also name four common viral diseases.

  Viruses are small infectious agents that can only replicate inside living host cells. They are composed of a nucleic acid genome, either DNA or RNA, surrounded by a protein coat called a capsid. Some viruses also have an envelope, which is a lipid membrane derived from the host cell membrane that surrounds the capsid. The genetic material of viruses can be either single-stranded or double-stranded, and can be either RNA or DNA. Some viruses, such as retroviruses, have RNA genomes that are reverse transcribed into DNA upon entering the host cell. Others, such as herpesviruses, have large DNA genomes. Some common viral diseases include: Influenza : a respiratory illness caused by the influenza virus, which can lead to fever, cough, sore throat, and body aches. HIV/AIDS : a viral infection caused by the human immunodeficiency virus (HIV), which attacks the immune system and can lead to acquired immunodeficiency syndrome (AIDS). Hepatitis : a group of viral infections that affect the...

Features of Lysosomes

 Features of Lysosomes: Structure: Lysosomes are small, spherical vesicles enclosed by a single membrane. They contain hydrolytic enzymes that are capable of breaking down almost all types of biomolecules, including proteins, nucleic acids, lipids, and carbohydrates. Function: Intracellular Digestion: Lysosomes digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria. This process is known as autophagy. Waste Removal: They help in removing waste materials and cellular debris by breaking them down into simpler compounds, which can either be reused by the cell or expelled as waste. Cellular Defense: Lysosomes play a role in protecting the cell by destroying harmful bacteria and viruses that invade the cell. Enzymes: The enzymes within lysosomes are called acid hydrolases. These enzymes work best in the acidic environment inside the lysosome (pH around 4.5-5.0), which is much lower than the pH of the cytosol (around 7.2). Formation: Lysosomes are forme...
