Question 1 of 5

What is the primary function of the endocrine system?

Correct Answer: D

Rationale: The correct answer is D: Homeostasis. The endocrine system is responsible for regulating various physiological processes to maintain internal balance, or homeostasis, within the body. Hormones released by endocrine glands help control metabolism, growth, reproduction, and other functions. Choice A (Heartbeat) is controlled by the cardiovascular system, not the endocrine system. Choice B (Respiration) is controlled by the respiratory system. Choice C (Electrolyte and water balance) is regulated by the kidneys and not directly by the endocrine system. Thus, the primary function of the endocrine system is to maintain homeostasis through hormone regulation.

Question 2 of 5

The acceleration of a falling object due to gravity has been proven to be 9.8 m/s�. A scientist drops a cactus four times and measures the acceleration with an accelerometer and gets the following results: 9.79 m/s�, 9.81 m/s�, 9.80 m/s�, and 9.78 m/s�. Which of the following accurately describes the measurements?

Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Question 4 of 5

Which blood component is responsible for the production of antibodies?

Correct Answer: C

Rationale: The correct answer is C: White blood cells. White blood cells, specifically lymphocytes, are responsible for producing antibodies as part of the immune response. Platelets are involved in blood clotting, not antibody production. Red blood cells carry oxygen and do not play a role in immune responses. Plasma cells are a type of white blood cell that produces antibodies, but they are a specialized subset of white blood cells and not the main component responsible for antibody production.

Question 5 of 5

If an organism is AB, which of the following combinations in the gametes is NOT possible?

Correct Answer: B

Rationale: The correct answer is B. If an organism is AB, it means they have alleles A and B. In gametes, each gamete carries only one allele. Therefore, gametes with AA are not possible as they lack the B allele. Gametes with AB are possible since they can carry either A or B allele. Gametes with BB are not possible as they lack the A allele. Gametes with AB are possible as they can carry either A or B allele.
