Answer:
The dependent variable would be B, whether or not the men develop baldness.
On the 12th day the Follicle Stimulating Hormone reach its peak concentration.
The Follicle stimulating hormone stimulates the growth of the egg-bearing follicles in the ovaries. The levels of Follicle stimulating hormone vary during the menstrual cycle and are best measured at its peak or baseline level. FSH levels level vary during the menstrual cycle, reaching their peak prior to ovulation. It is best to measure FSH on day three of the period via a blood sample which is called the baseline level. It provides the most accurate predictions of ovarian reserve.

Answer: Interventricular foramen
Explanation:
<u>The cerebrospinal fluid is a fluid that covers the brain and spinal cord. It circulates through the subarachnoid space, the cerebral ventricles and the ependymal canal</u>. Several diseases alter its composition and its study usually detects meningeal infections, carcinomatosis and hemorrhages. Some of its functions are:
- Hydropneumatic support against local pressure for the encephalon.
- Eliminates metabolites from the central nervous system.
- Protects the central nervous system from trauma.
This fluid also fills the ventricles, which are large open structures deep within the brain and help keep the brain buoyant and cushioned. The lateral ventricles are the largest ventricles and connect to the third ventricle through the intraventricular foramen. This third ventricle is a narrow, medial cavity located between the diencephalic masses. <u>Then, the interventricular foramina are channels that connect with the ventricles of the lateral walls and with the third ventricle</u>, at the level of the midline of the brain. Like these channels, they allow cerebrospinal fluid to circulate through the rest of the ventricular system of the brain. The walls of the foramina also contain choroid plexuses, responsible for the production of cerebrospinal fluid, which continue in both the lateral ventricles and the third ventricle. After reaching the third ventricle, the cerebrospinal fluid travels through the median aperture into the subarachnoid space at the base of the brain.
