1. Which of the following structures in the skin is responsible for producing sweat?

Correct answer: B

Rationale: The correct answer is B: Sudoriferous gland. Sudoriferous glands, also known as sweat glands, are responsible for producing sweat to regulate body temperature. Sebaceous glands produce sebum (oil) to lubricate the skin and hair. Hair follicles are associated with hair growth, not sweat production. Melanocytes are responsible for producing melanin for skin pigmentation, not sweat.

2. Which of the following statements best describes Newton's first law of motion?

Correct answer: A

Rationale: Newton's first law of motion, also known as the law of inertia, states that an object in motion will remain in motion, and an object at rest will remain at rest unless acted upon by an external force. This principle highlights the concept of inertia, which is the tendency of objects to resist changes in their state of motion. Option A accurately captures this fundamental aspect of Newton's first law. Options B, C, and D describe Newton's second law, third law, and the relationship between force, acceleration, and mass, respectively. Therefore, options B, C, and D are incorrect as they pertain to different laws formulated by Newton.

3. Which of the following are properties of a liquid?

Correct answer: D

Rationale: The correct answer is D: 'Takes shape of container.' Liquids exhibit the property of taking the shape of their container while maintaining a fixed volume. This is due to the ability of liquid particles to flow and move freely within the container. Choices A, B, and C are incorrect. Choice A, 'High atomic attraction,' is not a general property of liquids as the level of attraction between liquid particles can vary. Choice B, 'Fixed volume,' is partially correct as liquids do have a fixed volume, but they do not have a fixed shape. Choice C, 'Low pressure,' is not a defining property of liquids.

4. Which method is most suitable for measuring the volume of a cube?

Correct answer: B

Rationale: The correct answer is B. To measure the volume of a cube, you need to use a mathematical formula that takes into account the dimensions of the cube, specifically the length of its sides. Using a measuring wheel alone or a triple beam balance is not suitable for determining the volume of a cube. A graduated cylinder is used to measure the volume of liquids, not geometric solids like cubes.

5. Which hormone, produced by the adrenal glands, plays a crucial role in the body's response to stress, including the regulation of salt and water balance?

Correct answer: A

Rationale: Aldosterone is the correct answer. It is a hormone produced by the adrenal glands that plays a crucial role in the body's response to stress by regulating salt and water balance. Aldosterone acts on the kidneys to increase the reabsorption of sodium and water, helping to maintain blood pressure and electrolyte balance during stressful situations. Epinephrine, also known as adrenaline, and cortisol are other hormones produced by the adrenal glands, but they have different functions in the stress response. Epinephrine primarily acts to increase heart rate and blood flow in response to stress, while cortisol helps regulate metabolism, immune response, and inflammation. Insulin, on the other hand, is produced by the pancreas and is involved in regulating blood sugar levels, not salt and water balance.
