Which of the following is true?
A. In the human female, ovulation occurs in nine-month cycles.
B. Egg cells develop in a structure called the uterus and are released at the rate of one a month.
C. Spermatogenesis is the process of fertilization of the egg cell.
D. The fluid in which sperm cells "swim" during an ejaculation is produced by the prostate gland.
More like biology.
To determine which of the statements is true, let's evaluate each option one by one:
A. In the human female, ovulation occurs in nine-month cycles.
To determine if this statement is true, we need to understand what ovulation is. Ovulation is the release of an egg from the ovaries. In humans, it typically occurs once a month in women of reproductive age. However, the statement suggests that ovulation occurs in nine-month cycles, which is incorrect. Therefore, option A is not true.
B. Egg cells develop in a structure called the uterus and are released at the rate of one a month.
This statement suggests that egg cells develop in the uterus and are released at a rate of one per month. However, this is not accurate. Egg cells actually develop in the ovaries, not the uterus. Once the egg is mature, it is released from the ovary in a process called ovulation. Therefore, option B is not true.
C. Spermatogenesis is the process of fertilization of the egg cell.
To determine if this statement is true, we need to understand what spermatogenesis is. Spermatogenesis is the process of producing sperm cells in the testes. It is not the process of fertilizing the egg cell. Fertilization is the union of sperm and egg cells to form a zygote. Therefore, option C is not true.
D. The fluid in which sperm cells "swim" during an ejaculation is produced by the prostate gland.
To determine if this statement is true, we need to understand the role of the prostate gland in male reproductive system. The prostate gland produces a milky fluid that makes up a significant portion of semen, the fluid that carries sperm. This fluid helps to nourish and protect sperm cells. Therefore, option D is true.
In conclusion, the only true statement among the options provided is option D, which states that the fluid in which sperm cells "swim" during an ejaculation is produced by the prostate gland.
