2. The primary site for nutrient absorption from digested food in the human digestive system is the:

• A. Esophagus
• B. Large intestine
• C. Small intestine
• D. Stomach

Correct answer: C

Rationale: The correct answer is C: Small intestine. The small intestine is the primary site for nutrient absorption in the human digestive system. It is in the small intestine where the majority of nutrients, such as carbohydrates, proteins, and fats, are broken down further and absorbed into the bloodstream to be utilized by the body. The large surface area of the small intestine, lined with villi and microvilli, facilitates efficient absorption of nutrients. The esophagus is responsible for transporting food from the mouth to the stomach, the stomach aids in digestion, and the large intestine primarily absorbs water and electrolytes, not nutrients.

3. Identify the adjective in the following sentence: The colorful sunset painted the sky with vibrant hues.

• A. sunset
• B. with
• C. colorful
• D. painted

Correct answer: C

Rationale: Adjectives modify nouns and pronouns. The adjective "colorful" describes the noun "sunset".

4. Which of the following statements about fungi is FALSE?

• A. They can be unicellular or multicellular
• B. They are all parasitic and cause disease in humans
• C. They play a vital role in decomposition and nutrient cycling
• D. Some are used in food production, like mushrooms

Correct answer: B

Rationale: Rationale: A) This statement is true. Fungi can exist in both unicellular (yeast) and multicellular (molds and mushrooms) forms. B) This statement is false. While some fungi can be parasitic and cause diseases in humans, not all fungi exhibit this behavior. Many fungi are beneficial and play essential roles in ecosystems. C) This statement is true. Fungi are crucial for decomposition and nutrient cycling in ecosystems. They break down organic matter and recycle nutrients back into the environment. D) This statement is true. Some fungi, like mushrooms, are used in food production and are consumed by humans.

5. A doctor prescribes 150 milligrams of medication to be taken orally every 12 hours. How many grams should the patient take per dose?

• A. 0.015 grams
• B. 0.15 grams
• C. 1.5 grams
• D. 15 grams

Correct answer: A

Rationale: 1 gram is equal to 1000 milligrams. Divide the dosage in milligrams (150 mg) by the conversion factor (1000 mg/gram) to find the dosage in grams: 150 mg / 1000 mg/gram = 0.15 grams.

6. What is the process of breaking down lipids into fatty acids and glycerol called?

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

Correct answer: A

Rationale: Rationale: - Lipolysis is the process of breaking down lipids (fats) into fatty acids and glycerol. This process occurs in adipose tissue and is important for releasing stored energy in the form of fatty acids. - Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources like amino acids and glycerol, not breaking down lipids. - The Krebs cycle (also known as the citric acid cycle) is a series of chemical reactions that occur in the mitochondria to generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. - Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced through the transfer of electrons in the electron transport chain. It is not specifically related to the breakdown of lipids into fatty acids and glycerol.
