1. Q: What is the definition of life?
A: Life is a characteristic that distinguishes living organisms from non-living things.
2. Q: What are the basic life processes?
A: The basic life processes are nutrition, respiration, transportation, and excretion.
3. Q: What is autotrophic nutrition?
A: Autotrophic nutrition is the process by which organisms produce their own food.
4. Q: What is heterotrophic nutrition?
A: Heterotrophic nutrition is the process by which organisms obtain their food from other sources.
5. Q: What is respiration?
A: Respiration is the process by which organisms break down food to release energy.
6. Q: What is transportation?
A: Transportation is the movement of substances within an organism.
7. Q: What is excretion?
A: Excretion is the removal of waste products from an organism.
8. Q: What is diffusion?
A: Diffusion is the movement of particles from a region of high concentration to a region of low concentration.
9. Q: What is osmosis?
A: Osmosis is the movement of water molecules from a region of high concentration to a region of low concentration.
10. Q: What is active transport?
A: Active transport is the movement of particles from a region of low concentration to a region of high concentration using energy.
11. Q: What is the definition of control and coordination?
A: Control and coordination refer to the ability of an organism to regulate and integrate its various functions.
12. Q: What is the nervous system?
A: The nervous system is a system of specialized cells that transmit and process information.
13. Q: What is the difference between the central nervous system and the peripheral nervous system?
A: The central nervous system consists of the brain and spinal cord, while the peripheral nervous system consists of nerves that connect the central nervous system to the rest of the body.
14. Q: What is a reflex action?
A: A reflex action is a rapid, automatic response to a stimulus.
15. Q: What is the importance of control and coordination?
A: Control and coordination are essential for the survival and maintenance of living organisms.
Q21-30: Reproduction
21. Q: What is the definition of reproduction?
A: Reproduction is the process by which organisms produce offspring.
22. Q: What are the different modes of reproduction?
A: The different modes of reproduction are sexual reproduction and asexual reproduction.
23. Q: What is sexual reproduction?
A: Sexual reproduction is the process by which organisms produce offspring through the fusion of male and female gametes.
24. Q: What is asexual reproduction?
A: Asexual reproduction is the process by which organisms produce offspring without the fusion of gametes.
25. Q: What is the importance of reproduction?
A: Reproduction is essential for the continuation of a species.
31. Q: What is the definition of heredity?
A: Heredity is the passing of traits from parents to offspring.
32. Q: What is the definition of evolution?
A: Evolution is the change in the characteristics of a species over time.
33. Q: What is the theory of evolution?
A: The theory of evolution states that all living organisms have evolved from a common ancestor.
34. Q: What is natural selection?
A: Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce.
35. Q: What is the importance of heredity and evolution?
A: Heredity and evolution are essential for the diversity of life on Earth.
41. Q: What is the definition of environment?
A: Environment refers to the surroundings in which an organism lives.
42. Q: What are the different components of the environment?
A: The different components of the environment are biotic and abiotic factors.
43. Q: What is biodiversity?
A: Biodiversity refers to the variety of living organisms in an ecosystem.
44. Q: What is the importance of our environment?
A: Our environment is essential for our survival and well-being.
45. Q: What are the different types of ecosystems?
A: The different types of ecosystems are terrestrial, aquatic, and desert ecosystems.
