Anatomy

1. What is the muscular sac in the female body that nourishes and protects a developing fetus during pregnancy?

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus, also known as the womb, is a muscular sac in the female reproductive system where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment, support, and protection to the developing fetus until birth. The ovaries produce eggs, the fallopian tubes transport eggs to the uterus, and the vagina is the birth canal and the organ of sexual intercourse, but the uterus is specifically responsible for nurturing and protecting the developing fetus.

2. What is the process of cells dividing to produce new cells called?

Correct answer: A

Rationale: Rationale: A) Cell division is the process by which a parent cell divides into two or more daughter cells, allowing for growth, repair, and reproduction in living organisms. This process ensures that genetic material is accurately passed on to the new cells. B) Cell differentiation refers to the process by which cells become specialized to perform specific functions in an organism. While cell division is essential for cell differentiation, they are distinct processes. C) Cell growth is the increase in size or mass of a cell, which can occur before or after cell division. While cell growth is a component of the cell division process, it is not the primary process of cells dividing to produce new cells. D) Cell regeneration is the process by which damaged or lost cells are replaced by new cells. While cell division is involved in cell regeneration, it specifically refers to the overall process of cells dividing to produce new cells. Therefore, the most appropriate answer to the ques

3. Two coherent light waves with a slight phase difference interfere. What determines the resulting intensity of the combined wave?

Correct answer: A

Rationale: The intensity of the resulting wave depends on the individual intensities and the phase difference between the interfering waves. Constructive interference leads to higher intensity, while destructive interference leads to lower intensity.

4. What do isotopes of the same element have in common?

Correct answer: A

Rationale: Identical number of protons and neutrons - Isotopes have the same atomic number but different mass numbers due to varying neutron counts.

5. In meiosis I, how are sister chromatids distinguished from homologous chromosomes?

Correct answer: B

Rationale: While sister chromatids are identical copies of the same chromosome, homologous chromosomes are paired copies, each inherited from one parent. Crossing over during meiosis I can lead to slight differences in their DNA sequences.

6. Glands that release hormones directly into the bloodstream without ducts are called:

Correct answer: B

Rationale: The correct answer is B: Endocrine glands. Endocrine glands are specialized glands that release hormones directly into the bloodstream, which then travel to target organs or tissues to regulate various physiological processes. Unlike exocrine glands (choice A), which secrete their products through ducts to specific locations, endocrine glands secrete hormones into the blood for more widespread and systemic effects. Apocrine glands (choice C) release a portion of their cell contents along with the secretions, while merocrine glands (choice D) release their products through exocytosis without any loss of cell material. Therefore, in this case, endocrine glands best describe the glands that release hormones directly into the bloodstream without ducts.
