Correct answer: C

Rationale: The correct answer is C: Fallopian tube. Fertilization, the fusion of sperm and egg, typically occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels through the fallopian tube where it may encounter sperm for fertilization. The fertilized egg then moves to the uterus for implantation and development. The ovary releases the egg but fertilization occurs in the fallopian tube, making it the correct answer.

• A. Regulate insulin sensitivity and blood sugar levels
• B. Control blood pressure and electrolyte balance
• C. Stimulate the immune system and inflammatory response
• D. Promote growth and development during puberty

Correct answer: B

Rationale: The correct answer is B: 'Control blood pressure and electrolyte balance.' Corticosteroids, produced by the adrenal cortex, play a major role in regulating blood pressure and electrolyte balance in the body. These hormones, such as aldosterone, act on the kidneys to control the reabsorption of sodium and water, which in turn affects blood pressure and electrolyte levels. While corticosteroids can have effects on other physiological processes, their primary function is to regulate blood pressure and electrolyte balance, making option B the most appropriate choice in this context.

• A. Support
• B. Insulation
• C. Energy storage
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Adipose tissue, or fat, serves multiple functions in the body. It provides support by cushioning and protecting organs, acts as an insulation layer to maintain body temperature, and serves as a crucial energy storage site where excess energy is stored in the form of triglycerides. Therefore, all of the options listed (support, insulation, and energy storage) are accurate functions of adipose tissue.
