**Question 45****During the 12 hour period preceding ovulation, which of the following occurs?**- ○ A mucus plug at the cervix occurs, to keep sperm out.- ○ the number of developing corpus albicans is increasing.- ○ A surge of LH is secreted from the pituitary.- ○ The plasma concentration of progesterone is rising.**Explanation**This question is designed to test your understanding of the physiological changes that occur in a woman's body during the menstrual cycle, specifically in the period leading up to ovulation. Here's a brief explanation of each option to help you understand the correct context:1. **A mucus plug at the cervix occurs, to keep sperm out.** - This is typically not accurate in the context of ovulation. During ovulation, cervical mucus becomes thin and more permeable to aid sperm passage.2. **The number of developing corpus albicans is increasing.** - The corpus albicans is a degenerated form of the corpus luteum and typically increases during the latter phase after the ovulation if pregnancy does not occur.3. **A surge of LH is secreted from the pituitary.** - This is the correct answer. A surge of Luteinizing Hormone (LH) from the pituitary gland triggers ovulation. This hormone surge typically occurs about 24-36 hours before the egg is released from the ovary.4. **The plasma concentration of progesterone is rising.** - This typically occurs after ovulation has taken place, as the corpus luteum begins to secrete progesterone to prepare the endometrium for potential implantation.**Correct Answer: A surge of LH is secreted from the pituitary.**Understanding these hormonal changes is critical for comprehending reproductive physiology and can be beneficial for subjects dealing with fertility and menstrual health.

Hormones are the chemical molecules which acts as a chemical messenger for different body tissues…

Please help me answer question 13 and 14
hello! I would only like the bolded question please, the other questions are to provide background to the question. Describe the development of reproductive organs in a fetus of each gender. Which genes, gene products, and hormones are involved in the sex differences? Which sex- related hormones are circulating in high concentrations in a pregnant woman compared to a nonpregnant woman? Do these hormones cross the placenta (if you are uncertain, consider hormone chemical class relative to membrane permeability to make an educated guess)? Assuming these hormones do cross the placenta, how do they affect the hormonal environment inside the fetus, and how does this relate to fetal reproductive development
