1. Urine, the liquid waste product of the body, travels from the kidneys to the bladder through tubes called:

Correct answer: A

Rationale: The correct answer is 'Ureters.' Ureters are tubes that connect each kidney to the bladder. They transport urine from the kidneys to the bladder for storage before excretion. The urethra, which is not the correct answer, is responsible for carrying urine from the bladder out of the body. Nephrons, another incorrect choice, are microscopic units within the kidneys that filter blood and produce urine. The renal pelvis, also an incorrect choice, is a structure in the kidney where urine collects before moving into the ureters for further passage to the bladder.

2. Which of the following is the base that will bind with cytosine?

Correct answer: A

Rationale: Adenine is the correct answer as it is the base that binds with cytosine through hydrogen bonding in DNA, forming the A-T base pair. Cytosine always pairs with guanine to form the G-C base pair. Thymine pairs with adenine in DNA, not with cytosine.

3. What is the SI unit of measurement for acceleration?

Correct answer: D

Rationale: The SI unit of measurement for acceleration is meters per second squared (m/s²). Acceleration is defined as the rate of change of velocity over time. It is a vector quantity with dimensions of length per time squared. Meters per second squared (m/s²) represents the change in velocity (meters per second) over a specific time interval (seconds) squared. Choice A, meters per second (m/s), represents velocity, not acceleration. Choice B, Newton (N), is the unit of force. Choice C, Meters (m), represents only distance, not acceleration. Therefore, the correct unit for acceleration is meters per second squared (m/s²).

4. What is the first event to occur in a primary immune response?

Correct answer: A

Rationale: The correct answer is A. The initial event in a primary immune response is the phagocytosis of pathogens by macrophages and the subsequent presentation of their antigens, which is crucial for initiating the adaptive immune response. Neutrophils (Choice B) are also involved in the innate immune response, but they typically respond after macrophages. B lymphocytes (Choice C) produce antibodies later in the adaptive immune response, and Helper T cells (Choice D) help in coordinating the immune response but are not the first cells to act in a primary immune response.

5. Which property of a substance refers to its ability to be hammered or pressed into thin sheets without breaking?

Correct answer: A

Rationale: Malleability is the correct answer as it is the property of a substance that allows it to be hammered or pressed into thin sheets without breaking. This property is crucial for materials like metals that need to be shaped without breaking. Ductility, on the other hand, refers to the ability of a substance to be drawn into thin wires, not hammered into sheets. Viscosity is a measure of a fluid's resistance to flow, indicating its thickness or thinness, and is unrelated to the ability to be hammered. Conductivity, on the other hand, refers to a substance's ability to conduct electricity or heat, which is not related to its ability to be hammered or pressed into thin sheets.
