1. Which of the following is NOT a route of transmission for a sexually transmitted infection (STI)?

• A. Unprotected sexual contact
• B. Sharing contaminated needles
• C. Deep kissing
• D. Mother to child during childbirth

Correct answer: C

Rationale: Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.

2. A child's toy block is a cube with side lengths of 5cm. What is its total surface area?

• A. 25 sq cm
• B. 50 sq cm
• C. 125 sq
• D. 150 sq cm

Correct answer: D

Rationale: Use the formula for surface area of a cube: 6 * (side length)^2 = 6 * (5cm)^2 = 125 sq cm.

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

• A. Center of long bones
• B. Joints between bones
• C. Muscle tissue
• D. Walls of blood vessels

Correct answer: A

Rationale: Cartilage is a flexible connective tissue that is found in the joints between bones. It is a strong yet flexible tissue that cushions and supports the joints, allowing for smooth movement and reducing friction between bones. Cartilage is not typically found in the center of long bones, muscle tissue, or walls of blood vessels. Therefore, the correct answer is B: 'Joints between bones.'

4. Look at the following electron configuration: 1s2 2s2 2p6 3s2 3p6. To which group and period does this element belong?

• A. Group 16, Period 3
• B. Group 14, Period 3
• C. Group 18, Period 3
• D. Group 17, Period 2

Correct answer: C

Rationale: ) Group 18, Period 3. Count the total electrons (2 + 2 + 6 + 2 + 6 = 18) and observe the completely filled energy levels. This points to a noble gas in Group 18 (Neon) during Period 3.

5. The stratified cuboidal epithelium lining the salivary glands is responsible for:

• A. Protection
• B. Gas exchange
• C. Secretion
• D. Absorption

Correct answer: C

Rationale: The correct answer is C: Secretion. The stratified cuboidal epithelium lining the salivary glands is specifically designed for the secretion of saliva, which plays a crucial role in the initial digestion of food. This type of epithelium has multiple layers of cells that provide protection and support for the glandular tissue underneath, allowing for the production and release of saliva. Options A, B, and D are incorrect as they do not accurately reflect the primary function of this particular epithelium. Therefore, the correct choice is C, secretion.

6. 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.
