3. Which of the following is the primary function of the cell membrane?

• A. To provide structural support for the cell
• B. To transport substances in and out of the cell
• C. To synthesize proteins and lipids
• D. To store genetic material

Correct answer: B

Rationale: Rationale: The cell membrane, also known as the plasma membrane, plays a crucial role in regulating the movement of substances in and out of the cell. It is selectively permeable, meaning it allows certain molecules to pass through while blocking others. This function is essential for maintaining the internal environment of the cell and ensuring that necessary nutrients can enter the cell while waste products and other substances can exit. While the cell membrane does provide some structural support for the cell, its primary function is to control the transport of substances. The synthesis of proteins and lipids primarily occurs in other cellular organelles such as the endoplasmic reticulum and Golgi apparatus, while storing genetic material is the function of the nucleus.

4. Which skin condition is characterized by patches of inflamed, reddened skin and is often triggered by allergens or stress?

• A. Eczema
• B. Psoriasis
• C. Acne
• D. Vitiligo

Correct answer: A

Rationale: The correct answer is A: Eczema. Eczema is a skin condition characterized by patches of inflamed, reddened skin that can be triggered by allergens or stress. It is a chronic condition that can cause itching and discomfort. Psoriasis (option B) is a different skin condition characterized by red, scaly patches on the skin. Acne (option C) is a common skin condition characterized by pimples and clogged pores. Vitiligo (option D) is a condition where the skin loses its pigment, resulting in white patches. Therefore, eczema best fits the description provided in the question.

5. A table top has dimensions of 75cm by 50cm. What is its perimeter if opposite sides are equal?

• A. 125cm
• B. 150cm
• C. 200cm
• D. 50cm

Correct answer: B

Rationale: Rationale: - Given that the table top has dimensions of 75cm by 50cm. - Since opposite sides are equal, the table top can be divided into two pairs of equal sides: 75cm and 50cm. - To find the perimeter, we add up all four sides: 75cm + 50cm + 75cm + 50cm = 250cm. - However, since opposite sides are equal, we only need to consider two sides: 75cm + 50cm = 125cm. - Therefore, the perimeter of the table top is 125cm + 125cm = 150cm. - Hence, the correct answer is B) 150cm.

6. What is the involuntary process of emptying the bladder called?

• A. Filtration
• B. Micturition
• C. Reabsorption
• D. Excretion

Correct answer: B

Rationale: The correct answer is B: 'Micturition.' Micturition, also known as urination, is the involuntary process of emptying the bladder. During micturition, the bladder contracts while the sphincter muscles relax, allowing urine to be expelled from the body. Filtration (A) is the process of separating substances based on their size as they pass through a filter. Reabsorption (C) refers to the process of reclaiming substances from the filtrate in the renal tubules back into the bloodstream. Excretion (D) is the process of eliminating waste products from the body through urine, feces, sweat, or other means. Therefore, micturition is the specific term that describes the act of emptying the bladder involuntarily.
