Anatomy

1. Where does fertilization, the fusion of sperm and egg, typically occur in the human body?

Correct answer: C

Rationale: The correct answer is C: Fallopian tube. Fertilization, the fusion of sperm and egg, typically occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels through the fallopian tube where it may encounter sperm for fertilization. The fertilized egg then moves to the uterus for implantation and development. The ovary releases the egg but fertilization occurs in the fallopian tube, making it the correct answer.

2. The gradual change in a species over time is called:

Correct answer: B

Rationale: Rationale: - Adaptation refers to the process by which a species becomes better suited to its environment over time. While adaptation is a component of evolution, it specifically refers to the changes that help a species survive and reproduce in its environment. - Speciation is the process by which new species arise from a single ancestral species. It involves the evolution of reproductive isolation between populations. - Natural selection is a mechanism of evolution where individuals with advantageous traits are more likely to survive and reproduce, leading to the increase in frequency of those traits in a population. - Evolution is the gradual change in a species over time, encompassing all the processes such as adaptation, speciation, and natural selection that drive these changes.

3. Which type of energy is associated with the random motion of particles in a substance?

Correct answer: c

Rationale: Thermal energy is related to the random motion of particles in a substance and is associated with temperature.

4. Which of the following is the main organ responsible for producing antibodies?

Correct answer: C

Rationale: Rationale: Antibodies are proteins produced by specialized white blood cells called B lymphocytes (B cells). These B cells mature in the bone marrow, where they undergo a process of differentiation and maturation to become plasma cells that secrete antibodies. The bone marrow is the primary site for the production of B cells and antibodies in the immune system. The thymus gland is responsible for the maturation of T lymphocytes (T cells), not antibody production. The spleen and lymph nodes play roles in filtering and trapping pathogens but are not the main organs responsible for producing antibodies.

5. Which term describes a substance's ability to undergo a change that transforms it into a different substance?

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, transforming it into one or more different substances with new properties.

6. If 3 nurses can care for 15 patients, how many nurses are needed for 25 patients?

Correct answer: B

Rationale: 3 nurses / 15 patients = x nurses / 25 patients. Solve for x.
