1. What is the process of converting simple sugars into complex carbohydrates called?

• A. Glycolysis
• B. Gluconeogenesis
• C. Krebs cycle
• D. Oxidative phosphorylation

Correct answer: B

Rationale: Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate to produce energy. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources, such as amino acids or glycerol. C) The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. D) Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using energy derived from the electron transport chain.

2. What literary device is used in the line "The sea whispered secrets to the shore"?

• A. Alliteration
• B. Personification
• C. Onomatopoeia
• D. Hyperbole

Correct answer: B

Rationale: The sentence gives human qualities to the sea, like whispering, creating personification.

3. How does lymph move through the lymphatic vessels?

• A. By the pumping action of the heart
• B. Due to muscle contractions and breathing movements
• C. Through one-way valves within the vessels
• D. All of the above

Correct answer: D

Rationale: The correct answer is D: "All of the above." Lymph, a clear fluid that carries immune cells and waste products, moves through the lymphatic vessels by multiple mechanisms. While the pumping action of the heart plays a minor role, the primary driving forces are muscle contractions and breathing movements that squeeze the vessels. Additionally, lymphatic vessels contain one-way valves that prevent the backward flow of lymph, ensuring that it moves in the right direction. Therefore, all of the options provided contribute to the movement of lymph through the lymphatic system.

4. What is the unit of force in the SI system?

• A. Newton (N)
• B. Kilogram (kg)
• C. Meter (m)
• D. Second (s)

Correct answer: A

Rationale: Force is measured in Newtons, named after Isaac Newton who formulated the laws of motion.

5. A study finds a link between increased sugar intake and obesity. Does this confirm sugar causes obesity?

• A. Yes, the study definitively proves causation.
• B. No, correlation does not equal causation, other factors might be involved.
• C. We need more research to isolate the specific role of sugar.
• D. This only applies to people with genetic predispositions to obesity.

Correct answer: C

Rationale: Correlation suggests a link, but other factors might contribute. Further research is needed to establish the direction and strength of any causal relationship.

6. 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.
