Explanation:
Fertilization typically occurs in the ampulla, the widest region of the fallopian tube, where the sperm meets the secondary oocyte. The zygote then travels to the uterus for implantation. The ovary releases the egg, the uterus supports embryo development, the cervix is the lower portion opening into the vagina.
Explanation:
Luteinizing hormone (LH) binds to Leydig cells in the testes, stimulating them to produce and secrete testosterone. FSH stimulates Sertoli cells for spermatogenesis. GnRH from hypothalamus stimulates release of LH and FSH.
Explanation:
Bt brinjal is a transgenic eggplant (brinjal) developed by inserting the cry1Ac gene from the soil bacterium Bacillus thuringiensis (Bt). This gene codes for a crystal protein that is toxic to the larvae of the brinjal fruit and shoot borer (Leucinodes orbonalis), a major pest that causes significant yield loss. When the insect ingests the plant tissue, the alkaline gut activates the toxin, creating pores in the gut lining and killing the pest.
