Day 1.
Answer for Grade 10 Biology Entrance Exam Preparation Questions from Units 1 & 2:
1. Answer: C) Inorganic composition
Explanation: Living things are characterized by having organic composition, meaning they are made up of carbon-based molecules.
2. Answer: D) To systematically investigate natural phenomena
Explanation: The Scientific Method is a systematic approach to investigating natural phenomena through observation, hypothesis formation, experimentation, and conclusion drawing.
3. Answer: B) GPS device
Explanation: A GPS device is a field tool used by biologists for tracking locations but not specifically for biological research.
4. Answer: B) Condenser
Explanation: The condenser in a light microscope controls the amount of light that passes through the specimen to enhance visibility.
5. Answer: C) Read and understand the safety guidelines
Explanation: Understanding laboratory safety guidelines is crucial before conducting any experiments to prevent accidents and ensure a safe working environment.
6. Answer: A) Classifying living organisms
Explanation: Taxonomy is the science of classifying living organisms into groups based on shared characteristics.
7. Answer: C) Kingdom Protista
Explanation: Kingdom Protista includes unicellular eukaryotic organisms like algae and protozoa.
8. Answer: C) Carl Linnaeus
Explanation: Carl Linnaeus is known as the father of taxonomy for his work in developing the modern system of biological classification.
9. Answer: B) All living organisms are made up of cells
Explanation: The cell theory states that all living organisms are composed of one or more cells, which are the basic units of life.
10. Answer: B) Budding
Explanation: Budding is a form of asexual reproduction where a new organism develops as a growth on the parent organism.
11. Answer: D) Menstruation in females
Explanation: Menstruation is a secondary sexual characteristic that occurs during the menstrual cycle in females.
12. Answer: A) Production of sperm
Explanation: The primary function of the testes is to produce sperm through a process called spermatogenesis.
13. Answer: A) A cycle of hormonal changes in females
Explanation: The menstrual cycle is a series of hormonal changes and physical events that prepare the female body for pregnancy.
14. Answer: B) Substances that provide energy for cells
Explanation: Nutrients are substances that provide energy and essential components for cellular functions.
15. Answer: B) Pathogens such as bacteria and viruses
Explanation: Infectious diseases are caused by pathogens like bacteria, viruses, fungi, and parasites that invade the body and disrupt normal functions.
16. Answer: A) A community of organisms interacting with each other and their environment
Explanation: An ecosystem consists of living organisms interacting with each other and their physical environment.
17. Answer: B) Changes in the composition of a community over time
Explanation: Ecological succession refers to the gradual changes in the species composition of a community over time.
18. Answer: A) Living organisms
Explanation: Biotic components of an ecosystem include living organisms such as plants, animals, and microorganisms.
19. Answer: C) Yonas Yohannes
Explanation: Yonas Yohannes is a renowned taxonomist in Ethiopia known for his contributions to the study of Ethiopian flora and fauna.
20. Answer: A) By the energy requirement
Explanation: Active transport requires energy input to move molecules across a cell membrane, while passive transport does not require energy and occurs through diffusion or osmosis.
