1. What is the function of the amniotic fluid?

• A. Delivers food and oxygen to the developing organism
• B. Helps keep the temperature of the prenatal world constant
• C. Delivers nutrients and removes waste products
• D. Produces blood cells until the organs are mature enough to take over this function

Correct answer: B

Rationale: The correct answer is B: 'Helps keep the temperature of the prenatal world constant.' Amniotic fluid helps maintain a stable and warm environment for the developing organism, assisting in regulating the temperature. This fluid also acts as a cushion, protecting the fetus from physical harm. Choices A, C, and D are incorrect because while amniotic fluid provides protection and support to the developing organism, it does not directly deliver food, oxygen, nutrients, or remove waste products, nor does it produce blood cells as the organs eventually take over this function.

4. The immune response is the combined work of specialized cells that neutralize or destroy __________ in the body.

• A. T cells
• B. B cells
• C. telomeres
• D. antigens

Correct answer: D

Rationale: The correct answer is D, antigens. Antigens are substances recognized by the immune system as foreign, triggering an immune response to neutralize or destroy them. In this context, T cells and B cells are specialized cells of the immune system that respond to antigens, but they are not the substances being neutralized or destroyed. Telomeres, on the other hand, are protective structures at the end of chromosomes and are not targeted for neutralization or destruction by the immune system.

Jean Piaget focused more on individual cognitive development stages, Renée Baillargeon is known for her work in infant cognition and object permanence, and Noam Chomsky is renowned for his theories in linguistics and the study of language.
