1. Which of the following correctly completes the sentence? 'A childhood reading of Tales from Shakespeare permanently _____ Helene’s interest in studying the Great Bard.'

• A. piqued
• B. peaked
• C. peked
• D. peeked

Correct answer: A

Rationale: The word 'piqued' means to stimulate or arouse interest or curiosity. In this context, the sentence is referring to Helene’s interest in Shakespeare being stirred or awakened, which makes 'piqued' the correct word. Both 'peaked' and 'peeked' have different meanings (reaching the highest point and looking quickly, respectively) that do not fit the sentence. 'Peked' is not a valid word and does not make sense in the context of the sentence. Therefore, option 'A' is the correct choice.

2. Identify the determiner in the following sentence:

• A. happily
• B. branches
• C. few
• D. tree

Correct answer: C

Rationale: The determiner in the sentence is 'few.' Determiners specify the quantity or identity of a noun. In this case, 'few' indicates the number of birds present. Choice A, 'happily,' is an adverb modifying a verb or an adjective, not a determiner. Choice B, 'branches,' is a noun referring to parts of a tree, not a determiner. Choice D, 'tree,' is a noun identifying the main subject of the sentence, not a determiner.

3. What is the significance of the nuclear envelope breaking down during mitosis?

• A. It allows the chromosomes to condense and become visible.
• B. It allows the spindle apparatus to form and attach to the chromosomes.
• C. It allows the sister chromatids to separate.
• D. It allows the nuclear material to be evenly distributed to the daughter cells.

Correct answer: B

Rationale: A) The breakdown of the nuclear envelope does not directly cause the chromosomes to condense and become visible. Chromosome condensation is a separate process that occurs before mitosis begins. B) The breakdown of the nuclear envelope is crucial for the formation of the spindle apparatus, a structure made of microtubules that helps separate the chromosomes during cell division. The spindle apparatus attaches to the chromosomes and helps move them to opposite poles of the cell. C) The separation of sister chromatids occurs during anaphase, which is facilitated by the spindle apparatus. The breakdown of the nuclear envelope is not directly involved in this process. D) The even distribution of nuclear material to daughter cells is achieved through the movement of chromosomes by the spindle apparatus, which is made possible by the breakdown of the nuclear envelope.

4. What enzyme plays a key role in breaking down carbohydrates in the small intestine?

• A. Pepsin
• B. Lipase
• C. Amylase
• D. Trypsin

Correct answer: C

Rationale: Amylase is the enzyme responsible for breaking down carbohydrates in the small intestine. It specifically targets starches and sugars, breaking them down into smaller molecules like maltose and glucose that can be absorbed by the body. Pepsin is an enzyme that breaks down proteins in the stomach, not the small intestine. Lipase is responsible for breaking down fats, not carbohydrates. Trypsin is an enzyme that breaks down proteins in the small intestine, not carbohydrates.

5. Which of the following is responsible for the body's fight-or-flight response?

• A. Pancreas
• B. Adrenal glands
• C. Thyroid gland
• D. Pituitary gland

Correct answer: B

Rationale: The correct answer is B: Adrenal glands. The adrenal glands are responsible for the body's fight-or-flight response. During stressful situations, the adrenal glands release hormones like adrenaline and noradrenaline, initiating the fight-or-flight response. These hormones prepare the body to either confront or flee from a perceived threat.\nChoice A - Pancreas: The pancreas is primarily responsible for producing insulin and regulating blood sugar levels, not the fight-or-flight response.\nChoice C - Thyroid gland: The thyroid gland is responsible for producing hormones that regulate metabolism, not directly involved in the fight-or-flight response.\nChoice D - Pituitary gland: The pituitary gland regulates various endocrine functions by releasing hormones, but it is not the primary gland responsible for the fight-or-flight response.
