Q: Which of the following equations correctly represents the calculation of the probability of a child inheriting blood type O from two parents with genotypes AO and BO?

$$P(\text{O}) = P(\text{O allele from parent 1}) \times P(\text{O allele from parent 2}) = 0.5 \times 0.5 = 0.25$$

Question 1

Which of the following best describes the primary function of the lymphatic system in the human body?

Accepted Answer

Returning interstitial fluid to the bloodstream and providing immune defense

Question 2

A patient is exposed to a novel virus. Which type of immunity is responsible for the initial, nonspecific defense against this pathogen?

Accepted Answer

Innate immunity

Question 3

Which white blood cell type is most abundant in human blood and primarily responsible for phagocytosis of bacteria?

Accepted Answer

Neutrophils

Question 4

A person with blood type AB has which antigens present on their red blood cells?

Accepted Answer

Both A and B antigens

Question 5

Which hormone is primarily responsible for triggering ovulation in the female reproductive cycle?

Accepted Answer

Luteinizing hormone (LH)

Question 6

Compare and contrast oogenesis and spermatogenesis. Which statement is correct?

Accepted Answer

Oogenesis results in one functional ovum and three polar bodies, while spermatogenesis produces four functional sperm per precursor cell.

Question 7

Which of the following is a key difference between T lymphocytes and B lymphocytes?

Accepted Answer

T lymphocytes mature in the thymus, while B lymphocytes mature in the bone marrow.

Question 8

A patient is diagnosed with an autoimmune disease. Which of the following best describes the underlying cause?

Accepted Answer

The immune system attacks the body's own healthy cells.

Question 9

Which of the following equations correctly represents the calculation of the probability of a child inheriting blood type O from two parents with genotypes AO and BO?

Accepted Answer

$$P(	ext{O}) = P(	ext{O allele from parent 1}) 	imes P(	ext{O allele from parent 2}) = 0.5 	imes 0.5 = 0.25$$

Question 10

Which cell type is primarily involved in allergic reactions and releases histamine?

Accepted Answer

Basophils

Question 11

During embryonic development, which process describes the formation of the three primary germ layers?

Accepted Answer

Gastrulation

Question 12

Which hormone is produced by the corpus luteum and is essential for maintaining the uterine lining during early pregnancy?

Accepted Answer

Progesterone

Question 13

A patient presents with swollen lymph nodes and fever after a bacterial infection. Which lymphatic tissue is most likely involved in filtering the bacteria from lymph?

Accepted Answer

Lymph nodes

Question 14

Which of the following best explains the difference between primary and secondary lymphatic tissues?

Accepted Answer

Primary tissues are sites of lymphocyte development, while secondary tissues are sites of immune response activation.

Question 15

Which of the following is a function of monocytes in the immune system?

Accepted Answer

Differentiating into macrophages and phagocytosing pathogens

Question 16

Which of the following best describes the role of anti-Müllerian hormone (AMH) in the reproductive system?

Accepted Answer

Promotes development of male reproductive ducts and inhibits female duct formation during embryogenesis

Question 17

Which of the following is true regarding the immune response to viruses compared to bacteria?

Accepted Answer

Cell-mediated immunity is crucial for viruses, while antibodies are more effective against bacteria.

Question 18

A woman takes a pregnancy test 10 days after ovulation. Which hormone does the test detect to confirm pregnancy?

Accepted Answer

Human chorionic gonadotropin (hCG)

Question 19

Which of the following best describes the process of fertilization?

Accepted Answer

Fusion of a sperm cell and an ovum to form a zygote

Question 20

Which equation correctly represents the calculation of the expected number of sperm produced from one spermatogonium after meiosis?

Accepted Answer

$$N_{	ext{sperm}} = N_{	ext{cells}} 	imes 4$$
