1. Which of the following properties is characteristic of water?

Correct answer: D

Rationale: The correct answer is D because water's polarity enables it to dissolve a wide variety of substances, making it a versatile solvent. This property is due to water's ability to form hydrogen bonds with other molecules, allowing it to break them apart and surround the solute particles, facilitating dissolution. Choices A, B, and C are incorrect as water having a neutral pH, a high specific heat capacity, and polar covalent bonds are also true properties of water. However, the most relevant property related to its versatility as a solvent is its dissolving capability.

2. What is the scientific study of the relationships between organisms and their environment?

Correct answer: C

Rationale: Ecology is the scientific study of the relationships between organisms and their environment, including the interactions between living organisms and their physical surroundings. This field focuses on how organisms interact with each other and their environment. Zoology is the study of animals, Botany is the study of plants, and Genetics is the study of genes and heredity, which are not directly related to the relationships between organisms and their environment. Therefore, the correct answer is Ecology as it specifically deals with the interactions between living organisms and their environment.

3. Which of the following neurotransmitters is associated with the feeling of happiness and well-being?

Correct answer: B

Rationale: The correct answer is B: Serotonin. Serotonin is a neurotransmitter known for its role in mood regulation, promoting feelings of happiness and well-being. It helps regulate emotions, sleep, and appetite. Low levels of serotonin have been linked to conditions like depression and anxiety. Choice A, Dopamine, is more associated with pleasure and reward pathways in the brain. GABA (Choice C) is an inhibitory neurotransmitter involved in reducing neuronal excitability, not primarily linked to happiness. Acetylcholine (Choice D) is involved in muscle contraction and has functions related to memory and attention, but it is not primarily associated with feelings of happiness and well-being.

4. Which hormone is produced by the thyroid gland to regulate metabolism?

Correct answer: B

Rationale: Thyroxine, also known as T4, is the hormone produced by the thyroid gland to regulate metabolism. It is essential for controlling the body's metabolic rate, heart and digestive function, muscle control, brain development, and bone maintenance. Adrenaline is produced by the adrenal glands, not the thyroid gland. Cortisol is produced by the adrenal cortex, not the thyroid gland. Insulin is produced by the pancreas, not the thyroid gland. Therefore, the correct answer is Thyroxine (B).

5. Which of the following describes a responsibility of the integumentary system?

Correct answer: B

Rationale: The correct responsibility of the integumentary system is to act as a barrier that blocks pathogens from entering the body, thus helping to prevent diseases and infections. This function serves as the first line of defense for the body against external threats. Choices A, C, and D are incorrect. Choice A is a function of the circulatory system, not the integumentary system. Choice C relates to the lymphatic system, not the integumentary system. Choice D involves the endocrine system, not the integumentary system.
