1. What is the difference between type 1 and type 2 diabetes, both related to insulin and blood sugar?

• A. Type 1 is caused by insulin resistance, type 2 by insulin deficiency.
• B. Type 1 is temporary, type 2 is permanent.
• C. Type 1 affects adults, type 2 affects children
• D. Type 1 is treated with diet only, type 2 requires medication.

Correct answer: A

Rationale: The correct answer is A: 'Type 1 is caused by insulin resistance, type 2 by insulin deficiency.' Type 1 diabetes is an autoimmune condition where the body attacks insulin-producing cells, leading to insulin deficiency. In contrast, type 2 diabetes occurs when the body becomes resistant to insulin's effects. This distinction is crucial for understanding the underlying causes and treatment approaches for each type of diabetes. Type 1 diabetes is not temporary; it is a chronic condition that requires lifelong management. Type 2 diabetes can also affect adults, but it is more commonly diagnosed in middle-aged and older adults. Treatment for type 1 diabetes typically involves insulin therapy along with diet and exercise, while type 2 diabetes may require medication in addition to lifestyle modifications.

2. Identify the noun in the following sentence: The aroma of freshly baked bread filled the kitchen.

• A. filled
• B. kitchen
• C. aroma
• D. freshly

Correct answer: C

Rationale: Nouns name people, places, things, or ideas. "Aroma" names a specific type of smell.

3. Which type of cell division is responsible for sexual reproduction?

• A. Mitosis
• B. Meiosis
• C. Amitosis
• D. Cytokinesis

Correct answer: B

Rationale: Rationale: Meiosis is the type of cell division responsible for sexual reproduction. During meiosis, a single cell undergoes two rounds of division to produce four daughter cells, each with half the number of chromosomes as the parent cell. This reduction in chromosome number is essential for sexual reproduction, as it ensures that when two gametes (sperm and egg) combine during fertilization, the resulting zygote will have the correct number of chromosomes. Mitosis, on the other hand, is a type of cell division that produces two daughter cells with the same number of chromosomes as the parent cell and is involved in growth, repair, and asexual reproduction. Amitosis is a rare form of cell division that does not involve the typical processes of mitosis or meiosis. Cytokinesis is the process of dividing the cytoplasm of a cell after mitosis or meiosis.

4. Dense irregular connective tissue, found in tendons and ligaments, provides:

• A. Flexibility
• B. Lubrication
• C. Insulation
• D. Tensile strength

Correct answer: D

Rationale: The correct answer is D: 'Tensile strength.' Dense irregular connective tissue is composed of tightly packed collagen fibers arranged in a random pattern, providing resistance to tension forces. This structural arrangement is ideal for tendons and ligaments, as they need to withstand pulling and stretching forces. 'Flexibility' (A) is more characteristic of elastic fibers, 'Lubrication' (B) is provided by synovial fluid in joints, and 'Insulation' (C) is typically associated with adipose tissue. Therefore, tensile strength is the primary function of dense irregular connective tissue in tendons and ligaments.

5. Identify the conjunction in the following sentence: He went to the store, but they were already closed.

• A. went
• B. to
• C. but
• D. they

Correct answer: C

Rationale: Conjunctions connect words, phrases, or clauses. "But" joins two contrasting ideas in the sentence.

6. Two scientists analyze the same data set on climate change, but they reach different conclusions. What is the MOST likely reason for this difference?

• A. One scientist has more experience than the other.
• B. They used different statistical methods.
• C. They have different personal biases.
• D. One scientist has access to additional data.

Correct answer: B

Rationale: Different analysis methods can lead to different interpretations, even with the same data. Biases and experience might play a role but are less likely the primary cause.
