1. What is the primary function of nervous tissue?

Correct answer: C

Rationale: The primary function of nervous tissue is communication and coordination within the body. Nervous tissue is composed of neurons that transmit electrical signals and supporting cells known as neuroglia. Movement is primarily controlled by the muscular system, protection is mainly provided by the skeletal system and immune system, and nutrient transport is carried out by the circulatory system. Therefore, choices A, B, and D are incorrect as they do not align with the primary function of nervous tissue.

2. The immune response can be categorized into two main branches:

Correct answer: A

Rationale: - The immune response can be broadly categorized into two main branches: the humoral immune response and the cellular immune response. - The humoral immune response involves the production of antibodies by B cells and is primarily responsible for defending against extracellular pathogens such as bacteria and viruses in the bloodstream and tissues. - The cellular immune response involves the activation of T cells, which can directly kill infected cells or help coordinate the immune response. This branch is crucial for combating intracellular pathogens like viruses and some bacteria. - Options B, C, and D do not accurately represent the main branches of the immune response and are therefore incorrect.

3. What term describes the bouncing back of waves after striking a surface or boundary?

Correct answer: C

Rationale: The correct answer is 'Reflection.' Reflection is the term used to describe the bouncing back of waves after striking a surface or boundary. Diffraction, on the other hand, refers to the bending of waves around obstacles. Refraction is the bending of waves as they pass from one medium to another. Interference involves the combination of two or more waves that results in a new wave pattern. Therefore, in this context, choices A, B, and D are incorrect as they do not specifically relate to the bouncing back of waves after striking a surface or boundary.

4. What property of matter determines its resistance to changes in shape or size?

Correct answer: A

Rationale: The correct answer is 'Solid.' Solids have a definite shape and volume, providing them with a strong resistance to changes in shape or size. Liquids and gases do not have a definite shape, making them prone to changing shape or size easily. Plasmas, on the other hand, are ionized gases with high energy levels and lack a definite shape or volume, which does not contribute to resistance against changes in shape or size. Therefore, the properties of solids make them best suited for resisting changes in shape or size compared to liquids, gases, and plasmas.

5. What is the main target organ for insulin, the hormone produced by the pancreas?

Correct answer: C

Rationale: The main target organ for insulin is muscles. Insulin plays a crucial role in regulating glucose metabolism by promoting the uptake of glucose into muscle cells. This glucose can then be utilized for energy production or stored for later use. Therefore, muscles are the primary site where insulin exerts its effects on glucose uptake and utilization. The liver primarily responds to insulin by regulating glucose storage and release, but the main target for insulin-mediated glucose uptake is muscles. Kidneys are not a target organ for insulin action in glucose metabolism. The brain does not heavily rely on insulin for glucose uptake as it primarily uses glucose independently of insulin for energy production.
