1. What is the process by which a cell divides to produce two daughter cells?

Correct answer: A

Rationale: Mitosis is the correct answer because it is the process of cell division that results in the production of two daughter cells with identical genetic material to the parent cell. Meiosis, while also involving cell division, leads to the formation of gametes with half the number of chromosomes as the parent cell. Differentiation is the specialization of cells for specific functions, not the process of cell division. Transformation involves a cell incorporating foreign DNA into its genome, which is unrelated to the division of a cell into two daughter cells.

2. Which of the following is NOT a function of the lymphatic system?

Correct answer: B

Rationale: The correct answer is B. Releasing hormones is not a function of the lymphatic system. The lymphatic system plays crucial roles in removing substances from the blood, combating disease through the production of immune cells, and maintaining tissue fluid balance by circulating lymph. Releasing hormones is primarily the function of endocrine glands, not the lymphatic system.

3. What is the functional group present in amines?

Correct answer: C

Rationale: The functional group present in amines is the amine group, represented as -NH2. Amines are organic compounds characterized by the presence of a nitrogen atom bonded to hydrogen atoms. The amine group distinguishes amines from other types of organic compounds, such as alcohols with the hydroxyl group, ketones with the carbonyl group, and nitro compounds with the nitro group. Therefore, the correct answer is 'C: Amine.'

4. Adipose tissue, also known as fat, serves multiple functions. Which of these is NOT a function of adipose tissue?

Correct answer: D

Rationale: Adipose tissue serves multiple functions in the body, including insulation to regulate body temperature, energy storage in the form of triglycerides, and hormone production such as leptin and adiponectin. Adipose tissue does not directly participate in muscle movement. Muscle movement is primarily carried out by skeletal muscle tissue, which is responsible for voluntary movements and locomotion. Therefore, the correct answer is D, as adipose tissue is not involved in muscle movement.

5. What are the tiny contractile units within muscle cells called?

Correct answer: C

Rationale: Sarcomeres are the smallest contractile units within muscle cells. They consist of overlapping filaments of actin and myosin proteins, which interact to produce muscle contractions. Myocytes are the entire muscle cells, myofibrils are bundles of protein filaments found within muscle cells, and tendons are tough connective tissues that connect muscles to bones. Therefore, sarcomeres specifically represent the contractile units responsible for muscle contraction, making them the correct answer in this context.
