Which of the following is an example of ovoviviparity?
- A. Honeybees lay soft eggs within the hive
- B. Sharks hatch from shell-covered fertilized eggs within the female's body.
- C. Birds hatch from shell covered fertilized eggs laid within a nest.
- D. Fetal mammals obtain nourishment from the mother through a placent
Correct Answer: C
Rationale: Ovoviviparity is a reproductive strategy where fertilized eggs develop within the female's body but are not nourished by the mother. Choice C is correct because birds lay fertilized eggs within a nest where they hatch, indicating the eggs were developed internally. Choice A is incorrect as honeybees do not exhibit ovoviviparity. Choice B is incorrect as sharks exhibit viviparity, where embryos develop inside the mother but are nourished directly. Choice D is incorrect as it describes placental nourishment in mammals, which is not characteristic of ovoviviparity.

The superior portion of the uterus is the _____.
- A. body
- B. cervix
- C. fundus
- D. infundibulum
Correct Answer: C
Rationale: The correct answer is C: fundus. The fundus is the superior portion of the uterus, located above the entry point of the fallopian tubes. It is the part of the uterus where the fertilized egg implants and grows during pregnancy. The body of the uterus (choice A) is the main central portion, the cervix (choice B) is the lower narrow part that connects to the vagina, and the infundibulum (choice D) is a part of the fallopian tube, not the uterus. Thus, the fundus is the correct choice as it specifically refers to the superior portion of the uterus.

Step 3: The cyclical modifications of the mucous membrane are necessary for the shedding of the endometrium during menstruation.
Summary: Choice C is correct because it accurately describes a key function of the uterus related to the menstrual cycle. Choices A, B, and D are incorrect as they do not address the specific function of the uterine cavity and its mucous membrane modifications.
