Answer:
A. Estradiol
Explanation:
Estradiol, which is also referred to as 17 beta-estradiol, is an estrogen steroid hormone. This form of estrogen is one of the major female sex hormone that plays major role in the female reproductive system such as regulation of the estrous and menstrual cycle. It also helps in regulating body metabolism.
Reduction in the level of Estradiol is one of the problems common in women approaching menopause. Optimal level of estradiol in the body helps improve fertility in the body as symptoms such as such as vaginal dryness, burning, itching that are associated with menopause are reduced to the barest minimum.
The supplement taken by Priya in order to thin the mucus and allow sperm to get through the mucus to the uterus most likely works to benefit the body by increasing <em>estradiol.</em>
Gene regulation in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription. Any step of gene expression may be modulated, from the DNA-RNA transcription step to post-translational modification of a protein. The following is a list of stages where gene expression is regulated, the most extensively utilised point is Transcription Initiation: Chromatin domains.
Renal medulla
The renal medulla contains the renal pyramids, where urine formation takes place. Urine passes from the renal pyramids into the renal pelvis. This funnel-shaped structure occupies the central cavity of each kidney and then narrows as it extends out to join the ureter.
Answer:
