Biology

1. Which statement accurately describes cytokinesis in animal cells?

Correct answer: B

Rationale: Rationale: A) This statement is a duplicate of option C and does not accurately describe cytokinesis in animal cells. B) In animal cells, during cytokinesis, a cleavage furrow forms in the center of the dividing cell. This furrow deepens and eventually pinches the cytoplasm into two daughter cells. This process is distinct from plant cells, where a cell plate forms. C) This statement is a duplicate of option A and does not accurately describe cytokinesis in animal cells. D) This statement describes the process of nuclear division (mitosis) rather than cytokinesis, which is the division of the cytoplasm.

2. The tiny air sacs in the lungs where gas exchange takes place are called:

Correct answer: A

Rationale: The correct answer is C: 'Alveoli.' Alveoli are the tiny air sacs in the lungs where gas exchange takes place. Oxygen from the air is diffused into the blood, and carbon dioxide from the blood is diffused into the air in the alveoli. Bronchi (option A) are the large air passages that lead from the trachea into the lungs. Trachea (option B) is the windpipe that connects the larynx to the bronchi. Pleura (option D) is a thin membrane that surrounds the lungs and lines the chest cavity. Understanding these structures is essential for comprehending respiratory function and gas exchange in the human body.

3. Stephanie is often seen interacting with the medical intern during coffee breaks and after duty

Correct answer: B

Rationale: The correct answer is 'B: Informal.' Stephanie's interactions with the medical intern during coffee breaks and after duty suggest a casual and friendly relationship, rather than a formal or official one. 'Informal' describes interactions that are relaxed, personal, and not bound by strict professional protocols. In contrast, 'formal' interactions would involve more structured and official communication, such as meetings or professional discussions. 'Staff' and 'line' are not relevant in this context, as they do not describe the nature of the relationship between Stephanie and the medical intern.

4. What is the muscular sac in the female body that nourishes and protects a developing fetus?

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus is a muscular sac in the female body where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment to the developing fetus and protects it throughout gestation. The ovaries produce eggs, the fallopian tubes transport eggs from the ovaries to the uterus, and the vagina is the canal leading from the uterus to the outside of the body. Therefore, the uterus is the specific organ responsible for nourishing and protecting a developing fetus in the female body.

5. Deficiency in which vitamin can lead to a condition called pernicious anemia, affecting vitamin B12 absorption in the digestive system?

Correct answer: B

Rationale: The correct answer is B: Vitamin B12 (cobalamin). Pernicious anemia is a condition caused by a deficiency in vitamin B12, which is essential for the production of red blood cells and for the proper functioning of the nervous system. This vitamin is primarily absorbed in the digestive system, particularly in the ileum of the small intestine. In pernicious anemia, there is a lack of intrinsic factor, a protein produced by the stomach, which is necessary for the absorption of vitamin B12. Deficiencies in other vitamins like Vitamin A, Vitamin D, or Vitamin E do not directly lead to pernicious anemia. Therefore, the correct answer is Vitamin B12.

6. What is the pH of a solution with a hydrogen ion concentration of \(1 \times 10^{-9}\) M?

Correct answer: c

Rationale: The pH is calculated as the negative logarithm (base 10) of the hydrogen ion concentration. In this case, \(-\log(1 \times 10^{-9}) = 9\).
