Ten Biology General questions

1. What is the scientific study of life ?

Answer : Biology is the scientific study of life. It is the study of living organisms, from the smallest bacteria and viruses to the largest animals.

2. What is the cell theory ?

Answer : The cell theory states that all living organisms are composed of cells, that cells are the basic unit of structure and function for all living things, and that all cells come from pre-existing cells.

3. What is DNA ?

Answer : DNA, or deoxyribonucleic acid, is the genetic material present in almost all living organisms. It is a long molecule found in the nucleus of a cell and is composed of four different nitrogenous bases: adenine, guanine, cytosine, and thymine. DNA contains the instructions used by the cell to make proteins and enzymes.

4. What is the function of proteins ?

Answer : Proteins are molecules composed of amino acids and are responsible for a variety of functions in the body, including providing structure, transporting substances, and catalyzing biochemical reactions. They also act as hormones, enzymes, and antibodies.

5. What is the process of photosynthesis ?

Answer : Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. It occurs in the chloroplasts of plants and is the prime source of energy for life on earth.

6. What is the difference between prokaryotic and eukaryotic cells ?

Answer : Prokaryotic cells are simpler and smaller than eukaryotic cells. Prokaryotes lack a membrane-bound nucleus and organelles, while eukaryotic cells contain a nucleus and organelles.

7. What is the process of natural selection ?

Answer : Natural selection is the process by which organisms with certain favorable traits survive and reproduce more successfully than others in a given environment. This process of adaptation over time results in the evolution of a species.

8. What is the difference between classical and molecular genetics ?

Answer : Classical genetics is the study of heredity based on observable traits, while molecular genetics is the study of heredity at the molecular level, focusing on the structure and function of genes.

9. What is the difference between an organism and a species ?

Answer : An organism is an individual living thing, while a species is a group of organisms that are similar enough to interbreed and produce fertile offspring.

10. What is biomimicry ?

Answer : Biomimicry is the practice of using ideas and designs found in nature as models for creating products or systems. It is based on the idea that Nature has already figured out many of the things that we are still trying to figure out ourselves.

Gram staining | History | Application |Principle | Procedure

Gram Stain In 1884, Hans Christian Gram discovered a staining technique that could help to visualise the infectious bacteria clearly and can easily study their morphology. In this technique he used crystal violet (the primary dye), Gram’s iodine (IKI, the mordant), an alcohol rinse (decolorizer), Safranin (counter stain ). A Gram stain is a test that checks for bacteria at the site of a suspected infection such as the throat, lungs, genitals, or in skin wounds. Gram stains may also be used to check for bacteria in certain body fluids, such as blood or urine . This color choice provides differentiation between bacteria that stain purple, called gram-positive, and those that stain red, called gram-negative. The difference between gram-positive and gram-negative bacteria is due to the physical nature of their cell walls and how it reacts to the series of reagents applied to the cells . Gram positive bacteria has thick peptidoglyca...

How to make biology notes

Making biology notes is an important part of the learning process in biology. Notes help you remember important concepts and can also serve as a useful reference when you are revising. Here are some tips on how to make effective biology notes. First , it is important to choose an appropriate way to take notes. You can use a pen and paper, or you can type your notes on a laptop or tablet. The important thing is to choose a method that works best for you. Second , you should make sure to include all relevant information in your notes. This means that you should include the key points of the lesson as well as any diagrams, equations, formulas, and examples. It is also helpful to include any questions that you may have asked the teacher. Third , it is important to organize your notes in a way that is easy to understand and review. Color-code your notes, use headings, and highlight important points. This will help you to quickly reference important information during revision. Fourth ,...

FASINATING FACTS ABOUT MICROORGANISMS

Did you know... 1. If you pick up a handful of garden soil you will be holding hundreds if not thousands of different kinds of microbes. One single teaspoon of soil contains 1 billion bacteria & 120,000 fungi & 25,000 algae. 2. Microbes have been around longer than anything else on Earth, longer even than dinosaurs. If you imagine Earth began as a single day: Microbes appeared at 5am Dinosaurs appeared at 10pm... and humans appeared seconds before midnight 3. There are 10 times more bacteria in the average human's digestive system than there are cells in the entire body. This is approximately 1kg of bacteria. 4. There are more microbes on one person's hand than there are people on the planet. 5. Microbes generate at least half the oxygen we breathe. 6. Most microbes do not cause disease - less than 5% do. 7. Cattle belching and farting produce about 20% of the Earth's methane 8. A study found that 30% of all people didn't wash their hands after using a pu...
