Correct Answer: A
Rationale:
Question 2 of 5
What are the chemical messengers that control growth, differentiation, and the metabolism of specific target cells called?
Correct Answer: A
Rationale: Hormones are the correct answer. Hormones are signaling molecules produced by glands in the endocrine system. They travel through the bloodstream to target cells, where they regulate various physiological processes like growth, differentiation, and metabolism. Neurons are nerve cells that transmit information, glands produce and release hormones, and second messengers are molecules involved in intracellular signal transduction.

Question 4 of 5
Which type of cell secretes antibodies?
Correct Answer: D
Rationale: Plasma cells are a type of white blood cell specialized in producing and secreting antibodies. Antibodies, also known as immunoglobulins, are vital components of the immune system that help recognize and neutralize pathogens. When the body encounters an antigen, plasma cells are activated to produce and secrete antibodies specific to that antigen. These antibodies bind to the pathogen, marking it for destruction by other immune cells. Therefore, plasma cells are the correct answer as they are specifically designed to produce and secrete antibodies to fight infections.
Question 5 of 5
What percentage of a female's blood volume is composed of red blood cells?
Correct Answer: C
Rationale: Approximately 40% of a female's blood volume is composed of red blood cells, a proportion known as hematocrit. This percentage may vary slightly based on factors like age and overall health. Red blood cells play a crucial role in oxygen transport throughout the body, and deviations from the normal range can indicate various medical conditions.
