1. What is the second part of an organism’s scientific name?

• A. species
• B. phylum
• C. population
• D. kingdom

Correct answer: A

Rationale: The correct answer is 'species.' In binomial nomenclature, the second part of an organism's scientific name represents its species. The species name is a unique identifier within the genus and helps differentiate between different organisms within the same genus. Choices B, C, and D are incorrect. Phylum is a taxonomic rank higher than species, population refers to a group of organisms of the same species living in the same area, and kingdom is a taxonomic rank higher than genus.

2. What is the classification of organisms into different categories based on their physical characteristics and presumed natural relationship?

• A. Biology
• B. Taxonomy
• C. Grouping
• D. Nomenclature

Correct answer: B

Rationale: Taxonomy is the correct answer. Taxonomy is the branch of biology that deals with the classification of organisms into different categories based on their physical characteristics and presumed natural relationship. It involves naming and categorizing organisms into hierarchical groups to show their evolutionary relationships. Choice A, 'Biology,' is incorrect as it is the broader field of science that encompasses the study of living organisms. Choice C, 'Grouping,' is incorrect as it is a general term that does not specifically refer to the systematic classification of organisms. Choice D, 'Nomenclature,' is incorrect as it refers to the system of naming organisms rather than the classification based on physical characteristics and natural relationships.

3. What is the initial step in the metabolism of food to cellular energy?

• A. Citric Acid Cycle
• B. Glycolysis
• C. Electron Transport Chain
• D. Photosynthesis

Correct answer: B

Rationale: The correct answer is B: Glycolysis. Glycolysis is the initial step in the metabolism of food to cellular energy. During glycolysis, glucose is broken down into pyruvate, generating ATP and NADH. Choices A, C, and D are incorrect because the Citric Acid Cycle and Electron Transport Chain occur later in cellular respiration, while Photosynthesis is the process by which plants convert light energy into chemical energy.

4. How does water affect the temperature of a living thing?

• A. Water increases temperature.
• B. Water keeps temperature stable.
• C. Water decreases temperature.
• D. Water does not affect temperature.

Correct answer: B

Rationale: Water has a high specific heat capacity, which means it can absorb and release large amounts of heat with minimal temperature change. This property helps water regulate the temperature of living things by maintaining a stable environment. Choice A is incorrect because water does not consistently increase temperature, but rather helps in temperature regulation. Choice C is incorrect as water doesn't typically decrease temperature in living organisms. Choice D is incorrect since water does play a crucial role in regulating temperature.

5. What is the effect of the Earth's rotation on the atmosphere and on all objects on the Earth's surface?

• A. The Coriolis effect
• B. The Corona effect
• C. The Archimedes effect
• D. The tidal effect

Correct answer: A

Rationale: The Coriolis effect is the effect of the Earth's rotation on the atmosphere and on all objects on the Earth's surface. It causes moving objects and currents to be deflected to the right in the northern hemisphere and to the left in the southern hemisphere. This deflection is a result of the rotation of the Earth and plays a crucial role in influencing weather patterns and ocean currents around the globe. The other choices provided are incorrect. The Corona effect is related to the Sun's atmosphere, the Archimedes effect involves buoyancy in fluids, and the tidal effect is associated with the gravitational forces between the Earth, the Moon, and the Sun.
