1. Which hormone is responsible for lowering blood sugar levels?

• A. Glucagon
• B. Insulin
• C. Adrenaline
• D. Cortisol

Correct answer: B

Rationale: Insulin is the hormone responsible for lowering blood sugar levels. It is produced by the pancreas and facilitates the entry of glucose into cells, thereby reducing blood sugar levels. Glucagon, adrenaline, and cortisol have roles in increasing blood sugar levels through various mechanisms. Glucagon raises blood sugar levels by stimulating the liver to release stored glucose, adrenaline increases blood sugar in fight-or-flight responses, and cortisol raises blood sugar levels as part of the stress response. Therefore, in the context of lowering blood sugar levels, insulin is the correct answer.

2. What is the noun phrase in the following sentence?

• A. Puppy
• B. Charlotte
• C. German shepherd puppy
• D. Charlotte's new German shepherd puppy

Correct answer: D

Rationale: The correct answer is 'Charlotte's new German shepherd puppy.' A noun phrase is a group of words centered around a noun that functions as a subject, object, or complement within a sentence. In this sentence, 'Charlotte's new German shepherd puppy' is a noun phrase as it consists of multiple words ('Charlotte's,' 'new,' 'German shepherd,' 'puppy') and it serves as the subject of the sentence. Choice A, 'Puppy,' is not a complete noun phrase as it lacks the additional descriptors. Choice B, 'Charlotte,' is a proper noun and not a noun phrase. Choice C, 'German shepherd puppy,' is a noun phrase, but it does not include all the elements present in the complete noun phrase 'Charlotte's new German shepherd puppy.' Therefore, 'Charlotte's new German shepherd puppy' is the correct noun phrase in this sentence.

3. According to the prefix 'intra-,' which of the following is the best definition of the word 'intravenous'?

• A. Across veins
• B. Between veins
• C. Within veins
• D. Outside veins

Correct answer: C

Rationale: The prefix 'intra-' means 'within,' so 'intravenous' refers to something within veins. Choice A, 'Across veins,' is incorrect as 'intra-' does not indicate movement across but within. Choice B, 'Between veins,' is incorrect because 'intra-' does not imply a relationship between two separate veins. Choice D, 'Outside veins,' is incorrect as 'intra-' signifies something inside or within, not outside.

4. In which group of the periodic table are alkali metals located?

• A. Group 1
• B. Group 2
• C. Group 7
• D. Group 8

Correct answer: A

Rationale: Alkali metals, such as lithium, sodium, and potassium, are located in Group 1 of the periodic table. This group is known for its highly reactive properties, low melting points, and the tendency to form alkaline solutions when they react with water. Group 2 consists of alkaline earth metals and not alkali metals, making choice B incorrect. Group 7 includes halogens, while Group 8 includes noble gases. These groups do not contain alkali metals, so choices C and D are also incorrect. Therefore, the correct answer is Group 1.

5. What do large intestines absorb?

• A. Water, sodium, and potassium ions
• B. Proteins and carbohydrates
• C. Water, vitamin K, and bile salts
• D. Vitamins A, D, E, K

Correct answer: C

Rationale: The correct answer is C. The large intestine absorbs water, vitamin K, bile salts, sodium, and chloride ions. It helps in maintaining the body's water and electrolyte balance, and also plays a role in absorbing certain vitamins and nutrients such as vitamin K. Choices A, B, and D are incorrect because proteins, carbohydrates, vitamins A, D, E, and K are primarily absorbed in the small intestine, not the large intestine.
