1. After graduating from Proviso East High School in 1966, he later went on to study law at Triton Junior College. Which of these sentences, if any, should begin a new paragraph?

• A. There should be no new paragraph.
• B. After graduating from Proviso East High School in 1966, he later went on to study law at Triton Junior College.
• C. While studying at Triton, Hampton joined and became a leader of the National Association for the Advancement of Colored People (NAACP).
• D. As a result of his leadership, the NAACP gained more than 500 members.

Correct answer: B

Rationale: The sentence 'After graduating from Proviso East High School in 1966, he later went on to study law at Triton Junior College' marks a shift in the narrative as it introduces a new stage in the individual's journey. This change in focus warrants starting a new paragraph to clearly separate different events or developments in the person's life. Choices C and D are related to Hampton's actions during or after his time at Triton College but do not necessitate a new paragraph. Choice A is incorrect because the sentence provided is a suitable candidate for starting a new paragraph due to the change in the main topic it introduces.

2. What is the breakdown product of creatine phosphate, an energy source used for short bursts of muscle activity?

• A. Glucose
• B. Lactic acid
• C. Carbon dioxide
• D. Creatine

Correct answer: B

Rationale: Creatine phosphate is utilized as an immediate energy source for short bursts of muscle activity. When it breaks down, it yields lactic acid as a byproduct. Lactic acid accumulation during intense exercise can lead to muscle fatigue and soreness. Therefore, the correct answer is lactic acid. The other choices are incorrect: Glucose is a different energy source derived from carbohydrates; Carbon dioxide is a waste product of cellular respiration, not specifically from creatine phosphate breakdown; Creatine is the precursor compound to creatine phosphate and is not the breakdown product.

3. Which of the following is not a component of blood?

• A. Red blood cells
• B. White blood cells
• C. Platelets
• D. Cartilage

Correct answer: D

Rationale: The correct answer is D: Cartilage. Cartilage is not a component of blood. Blood primarily consists of red blood cells, white blood cells, and platelets. Red blood cells are responsible for carrying oxygen, white blood cells are part of the immune system, and platelets are essential for blood clotting. Cartilage, on the other hand, is a type of connective tissue found in various parts of the body, such as the joints and nose, but it is not present in the blood. Therefore, choices A, B, and C are incorrect as they are components of blood, while choice D, Cartilage, is the correct answer as it is not a component of blood.

4. Which of the following functional groups is present in carboxylic acids?

• A. Carbonyl
• B. Hydroxyl
• C. Carboxyl
• D. Aldehyde

Correct answer: C

Rationale: Carboxylic acids contain the carboxyl functional group, which consists of a carbonyl group (C=O) and a hydroxyl group (-OH) attached to the same carbon atom. The carboxyl group is represented as -COOH in the molecular structure of carboxylic acids. Therefore, the correct functional group present in carboxylic acids is the carboxyl group, making option C the correct choice. Option A, 'Carbonyl,' is incorrect as it only refers to the C=O group without the -OH component present in carboxylic acids. Option B, 'Hydroxyl,' is incorrect as it only represents the -OH group without the carbonyl group. Option D, 'Aldehyde,' is incorrect as it refers to a different functional group with a carbonyl group attached to a hydrogen atom, not the carboxyl group found in carboxylic acids.

5. What is the significance of cell division?

• A. Growth and repair of tissues
• B. Sexual reproduction
• C. Genetic diversity
• D. All of the above

Correct answer: D

Rationale: Cell division is a fundamental process that serves multiple critical functions in living organisms. It is essential for the growth and repair of tissues by enabling the formation of new cells to replace old or damaged ones. Moreover, cell division plays a pivotal role in sexual reproduction as it is involved in the production of gametes necessary for fertilization. Additionally, cell division contributes to genetic diversity through processes like meiosis, which leads to the formation of genetically distinct gametes. Therefore, the correct answer is D, 'All of the above,' as cell division is significant for growth, repair, sexual reproduction, and genetic diversity. Choices A, B, and C are incorrect because they each represent only one aspect of the significance of cell division, whereas the correct answer encompasses all the essential roles that cell division plays in living organisms.
