The cell produced by fertilization is called
- A. gamete
- B. embryo
- C. fetus
- D. zygote
Correct Answer: D
Rationale: The correct answer is D: zygote. After fertilization, the sperm and egg unite to form a zygote, which is the initial cell of a new organism with a full set of chromosomes. A gamete (A) is a reproductive cell before fertilization, an embryo (B) is the early stage of development after the zygote, and a fetus (C) is the later stage of development in the womb. Therefore, the zygote is the correct term for the cell produced by fertilization.

Variations in eye color are determined by the number of pigmented cells in the:
- A. Ciliary epithelium
- B. Iris epithelium
- C. Iris stroma
- D. Corneal stroma
Correct Answer: C
Rationale: The correct answer is C: Iris stroma. The iris stroma contains melanocytes, which are responsible for producing the pigmented cells that determine eye color. These pigmented cells give the iris its color by absorbing and reflecting light. The ciliary epithelium (choice A) is not involved in determining eye color. The iris epithelium (choice B) is mainly responsible for controlling the size of the pupil, not for determining eye color. The corneal stroma (choice D) is a layer of the cornea that primarily provides structural support and transparency to the eye, but it does not play a role in determining eye color.
The ducts or tubes responsible for the ________. receiving the ovulated oocyte and
- A. glans penis providing the site for fertilization are
- B. shaft the ________.
- C. scrotum
- D. uterine (fallopian) tubes
Correct Answer: D
Rationale: The correct answer is D: uterine (fallopian) tubes. These tubes are responsible for receiving the ovulated oocyte (egg) and providing the site for fertilization. The fallopian tubes are specifically designed to transport the egg from the ovary to the uterus for potential fertilization by sperm. Choice A, glans penis, is incorrect as it is part of the male reproductive system and not involved in receiving the ovulated egg. Choice B, shaft, is also incorrect as it refers to the main part of the penis and is not related to female reproductive functions. Choice C, scrotum, is incorrect as it is part of the male reproductive system and has no role in receiving the ovulated egg.

The epididymis:
- A. is comm
- B. shaped;
- C. is crossed by the deferent duct (vas deferens);
- D. displays tunica albuginea on the inside;
Correct Answer: C
Rationale: Step 1: The epididymis is a structure where sperm mature and are stored.
Step 2: The deferent duct (vas deferens) carries sperm from the epididymis to the urethra.
Step 3: Since the deferent duct crosses the epididymis, choice C is correct.
Summary: Choices A, B, and D are incorrect because they do not accurately describe the anatomical relationship between the epididymis and the deferent duct.
