1. The process by which two or more species reciprocally influence each other's evolution through selection pressures exerted on one another is called:

Correct answer: C

Rationale: A) Convergent evolution refers to the process by which unrelated species evolve similar traits due to similar environmental pressures. This does not involve reciprocal influence between species. B) Divergent evolution refers to the process by which two or more related species become more dissimilar over time due to different selection pressures. This also does not involve reciprocal influence between species. C) Coevolution is the process by which two or more species reciprocally influence each other's evolution through selection pressures exerted on one another. This can lead to a close ecological relationship between the species, such as in predator-prey interactions or mutualistic relationships. D) This option is a duplicate of option C.

2. Which molecule is responsible for storing and providing a quick source of energy during short bursts of intense physical activity, such as weightlifting or sprinting?

Correct answer: A

Rationale: ATP (Adenosine Triphosphate) is the molecule responsible for storing and providing a quick source of energy during short bursts of intense physical activity like weightlifting or sprinting. ATP is broken down to release energy rapidly when muscles need quick, intense efforts. Glucose is a source of energy but must be converted into ATP before it can be used by muscles. Myoglobin is a protein that stores oxygen in muscle cells and does not directly provide energy. Lactic acid is produced during intense exercise but is not the primary molecule responsible for providing quick energy during short bursts of intense physical activities.

3. Which of the following is the largest organ in the human body?

Correct answer: D

Rationale: The skin is the largest organ in the human body. It covers the entire body, serving as a protective barrier against pathogens, UV radiation, and physical damage. Additionally, the skin plays a crucial role in regulating body temperature and synthesizing vitamin D when exposed to sunlight. Choices A, B, and C are incorrect. The liver is the largest internal organ, the brain is the control center of the body, and the heart is a vital organ responsible for pumping blood throughout the body. However, none of these organs are the largest in terms of surface area or overall size.

4. How many different types of tissue are there in the human body?

Correct answer: A

Rationale: The correct answer is A: 4. There are 4 types of tissues in the human body: epithelial, connective, muscle, and nervous. Epithelial tissue covers the body surfaces, connective tissue provides support and structure, muscle tissue enables movement, and nervous tissue transmits signals. Choices B, C, and D are incorrect as they do not represent the accurate number of tissue types found in the human body.

5. Which of the following is considered an extensive property?

Correct answer: A

Rationale: Weight is correctly identified as an extensive property. Extensive properties are dependent on the amount of the substance present. Weight is directly proportional to the quantity of the substance, making it an extensive property. In contrast, density, conductivity, and malleability are intensive properties, which remain constant regardless of the amount of substance. Therefore, the correct answer is 'Weight' as it changes with the quantity of the substance, aligning with the definition of an extensive property.
