1. Which of the following are the products of anaerobic respiration in humans?

Correct answer: C

Rationale: During anaerobic respiration in humans, lactic acid and CO2 are produced. Choice A, 'Ethyl alcohol and CO2,' is incorrect because ethyl alcohol is not a product of anaerobic respiration in humans. Choice B, 'Ethyl alcohol only,' is incorrect as ethyl alcohol is not a product of anaerobic respiration in humans. Choice D, 'Lactic acid only,' is incorrect because CO2 is also a product of anaerobic respiration in humans.

2. Which of the following constituents of blood is a biconcave disc that is round and flat without a nucleus?

Correct answer: C

Rationale: The correct answer is C, RBC (Red Blood Cell). Red blood cells are biconcave discs that lack a nucleus, allowing them to carry oxygen efficiently. Plasma (A) is the liquid component of blood that carries various substances. Platelets (B) are cell fragments important for blood clotting. White blood cells (WBCs) (D) are part of the immune system and have a nucleus.

3. Which of the following is a MAJOR consequence of a stroke?

Correct answer: C

Rationale: A major consequence of a stroke is brain damage due to interrupted blood flow. Strokes occur when blood flow to the brain is blocked or reduced, leading to the death of brain cells. This interruption in blood flow results in brain damage, which can cause physical and cognitive impairments such as paralysis, speech difficulties, memory problems, and sensory disturbances. The severity and location of the stroke determine the extent of the consequences experienced by the individual. Choices A, B, and D are incorrect. Irregular heart rhythm is not a direct consequence of a stroke but may occur as a complication. Rapid weight gain or loss and chronic fatigue with muscle weakness are not typically considered major consequences of a stroke, which primarily affects the brain due to interrupted blood flow.

4. What is the formula for calculating density?

Correct answer: A

Rationale: Density is defined as the amount of mass in a given volume. The formula for calculating density is Density = Mass / Volume. This means that you divide the mass of an object by its volume to determine its density. Therefore, the correct formula for calculating density is Density = Volume / Mass. Choice A is correct because density is calculated by dividing the volume by the mass. Choices B, C, and D are incorrect because they do not represent the correct relationship between mass and volume in calculating density.

5. Cartilage is a flexible connective tissue found in the:

Correct answer: B

Rationale: Cartilage is a flexible connective tissue found in the joints between bones. It provides cushioning and support for the bones, allowing smooth movement and reducing friction between them. Cartilage acts as a shock absorber and helps maintain the structural integrity of the joints. Choices A, C, and D are incorrect because cartilage is not typically found in the center of long bones, muscle tissue, or the walls of blood vessels. Cartilage primarily functions in providing structural support and flexibility in joints.
