Anatomy

1. The muscular tube that carries urine from the kidneys to the bladder is called the:

Correct answer: B

Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. Nephrons are the functional units of the kidneys responsible for filtering blood. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a cluster of blood vessels in the nephron that filters blood to form urine. Understanding the functions and locations of these structures is essential for comprehending the urinary system's overall process.

2. What part of speech is the underlined word in the sentence: "He felt a growing sense of unease"?

Correct answer: B

Rationale: "Sense" represents a concept or feeling, making it a noun here.

3. The WBC (white blood cell) type responsible for the initial attack on pathogens is:

Correct answer: C

Rationale: The correct answer is C: Phagocytes. Phagocytes are a type of white blood cell that plays a crucial role in the immune response by engulfing and destroying pathogens. They are the first line of defense against invading microorganisms, initiating the initial attack on pathogens. Red blood cells (option A) are responsible for carrying oxygen, not for immune responses. Platelets (option B) are involved in blood clotting. Lymphocytes (option D) are another type of white blood cell but are mainly responsible for specific immune responses rather than the initial attack on pathogens.

4. A bag contains 5 red marbles and 7 blue marbles. If you draw a marble without looking, what is the probability it will be red?

Correct answer: A

Rationale: Divide the number of red marbles (5) by the total number of marbles (12) to get 1/3 probability.

5. A scientific theory is:

Correct answer: B

Rationale: Theories in science are constantly evolving and open to revision as new data emerges, unlike personal beliefs or fixed dogmas.

6. The term "double circulation" in the cardiovascular system refers to

Correct answer: D

Rationale: The term 'double circulation' in the cardiovascular system refers to the existence of two separate circulatory pathways, one for the lungs (pulmonary circulation) and one for the body (systemic circulation). In pulmonary circulation, deoxygenated blood is pumped from the heart to the lungs to pick up oxygen and release carbon dioxide. Then, oxygenated blood returns to the heart to be pumped out to the rest of the body in systemic circulation. This separation of oxygenated and deoxygenated blood flow in different pathways is what distinguishes the double circulation system. Therefore, option D is the correct answer as it accurately describes the concept of double circulation in the cardiovascular system.
