Answer:
Role of nervous system in Parkinson's disease:
Parkinson's disease is a neuro disorder that affects the nerve cells. The neurons responsible for the body movement is affected in this disease. The neurons that produce dopamine, dies in the parkinson's disease and result in the conditions like slowness, tremor and stiffness.
Role of nervous system in Alzheimer's disease:
Alzheimer's disease is a type of dementia that loses the individual's ability to think and memorize the things. The brain tissue is degenerated in this disease. The nerve cell loses its function and the protein beta amyloid get deposited in this disease.
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
Answer:
A. Inhibit FSH secretion.
Explanation:
Inhibin is a hormone secreted by the granulosa cells in the ovaries of women and the Sertolli cells in men. The main function of inhibin, as they name says, is to inhibit the secretion of FSH by the anterior pituitary gland. Inhibin is also produced by the Sertolli cells in the testes of men, and it is released in the blood when the sperm count is too high. FSH causes the Sertoli cells of the testes to begin the process of spermatogenesis in the testes. Therefore, releasing inhibin would cause a negative feedback and stop the production of sperm.
