Question 1 of 5
What is the function of the milky-colored fluids secreted from the prostate?
Correct Answer: C
Rationale: The milky-colored fluid secreted from the prostate cleanses the urethra. This fluid helps neutralize the acidity of the urethra, providing a more suitable environment for sperm to survive. It does not enable sperm to swim or activate them, as these functions are performed by other components of semen. Additionally, it does not neutralize urine, as its primary function is to support sperm survival and motility.
Question 2 of 5
The egg is fertilized in which anatomical structure?
Correct Answer: B
Rationale: The correct answer is B: Uterus. After fertilization, the egg travels through the fallopian tube and implants in the uterus for further development. The vagina is the birth canal, not the site of fertilization. The fallopian tube is where fertilization typically occurs, but the actual implantation of the fertilized egg occurs in the uterus. The cervix is the lower part of the uterus that connects to the vagina and plays a role in pregnancy but is not where fertilization occurs.
Question 3 of 5
Of the two functional areas of the years of age is known as ________. It blastocyst, the three primary germ is during this time that the reproductive layers form from the ________. organs grow to their adult size and
Correct Answer: D
Rationale: The correct answer is D: adulthood. The question is referring to the two functional areas of life - childhood and adulthood. During adulthood, organs grow to their adult size and mature, reproductive organs become functional under the influence of hormones. A: amnion become functional under the influence - Incorrect. Amnion is a membrane surrounding the embryo, not related to the functional areas of age. B: morula of hormones - Incorrect. Morula is an early stage of embryonic development, not related to the functional areas of age. C: inner cell mass - Incorrect. Inner cell mass is a part of the blastocyst, not related to the functional areas of age.
Question 4 of 5
The hormone(s) responsible for hymen. secondary sex characteristics in
Correct Answer: B
Rationale: The correct answer is B: estrogens. Estrogens are the primary hormones responsible for the development of secondary sex characteristics in females, including the formation of the hymen. Estrogens play a crucial role in regulating menstrual cycles, breast development, and overall reproductive health in females. Progesterone (choice D) is primarily involved in regulating the menstrual cycle and supporting pregnancy but is not directly responsible for hymen development. Choices A and C do not provide accurate or relevant information related to the development of secondary sex characteristics or the hymen.
Question 5 of 5
Primary spermatogonium undergo:
Correct Answer: B
Rationale: The correct answer is B. Primary spermatogonium undergo mitosis to replicate and maintain the diploid chromosome number, then meiosis to reduce the chromosome number, resulting in secondary spermatocytes. Choice A is incorrect as it skips meiosis. Choice C is incorrect as it suggests two meiotic divisions from primary spermatogonium, which is not accurate. Choice D is incorrect because it fails to mention the initial step of mitosis before meiosis in the process.
