Biology Test

1. What is the science of biological classification commonly called?

Correct answer: A

Rationale: Taxonomy is the science of naming, defining, and classifying groups of biological organisms based on shared characteristics. Physiology (choice B) is the study of the functions and processes of living organisms, not classification. Botany (choice C) is the study of plants, while Zoology (choice D) is the study of animals. Therefore, the correct answer is Taxonomy (choice A).

2. What is located on the rough endoplasmic reticulum?

Correct answer: D

Rationale: The rough endoplasmic reticulum is studded with ribosomes, not microvilli, mitochondria, or lysosomes. Ribosomes are responsible for protein synthesis, making them an essential component of the rough endoplasmic reticulum.

3. Which of the following options identifies the products of cell respiration?

Correct answer: C

Rationale: The correct answer is C: 'Water, carbon dioxide, and adenosine triphosphate (ATP).' During cellular respiration, glucose is broken down in the presence of oxygen to produce water, carbon dioxide, and ATP. Choice A is incorrect as oxygen is not a product of cell respiration but a reactant. Choice B is incorrect as it lists glucose and oxygen, which are actually reactants in the process. Choice D is incorrect as glucose is not a product of cell respiration but a substrate that is broken down to release energy.

4. Asexual reproduction is a type of reproduction by which offspring arise from:

Correct answer: B

Rationale: Asexual reproduction is a type of reproduction where a single parent cell divides to produce genetically identical offspring. The correct answer is 'B: A single cell' because asexual reproduction does not involve the fusion of two cells. Choice A ('Two identical cells') is incorrect because asexual reproduction does not involve two cells. Choice C ('Two cells') is incorrect because asexual reproduction typically involves only one parent cell. Choice D ('Four daughter cells') is incorrect because asexual reproduction does not necessarily involve the production of four daughter cells.

5. During which stage of photosynthesis is solar energy converted to chemical energy?

Correct answer: B

Rationale: The correct answer is B, during the light reactions. During the light reactions of photosynthesis, solar energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH. Choice A is incorrect as phosphate synthesis does not involve the conversion of solar energy. Choice C, the Krebs cycle, is a part of cellular respiration, not photosynthesis. Choice D, the Calvin cycle, is responsible for fixing carbon dioxide into carbohydrates and does not involve the direct conversion of solar energy to chemical energy.
