A Sertoli cell (a kind of sustentacular cell) is a "nurse" cell of the testicles that is part of a seminiferous tubule and helps in the process of spermatogenesis; that is, the production of sperm.
It is activated by follicle-stimulating hormone (FSH) secreted by the adenohypophysis, and has FSH receptor on its membranes. It is specifically located in the convoluted seminiferous tubules (since this is the only place in the testes where the spermatozoa are produced). Development of Sertoli cells is directed by the testis-determining factor protein.

The phenotype of an organism is a collection of its observable traits or characteristics. The term describes the physical form and structure of an organism as well as its physiological and biochemical traits, behavior, and results of that behavior. The blood clots incorrectly as a result of hemophilia, a genetic bleeding disorder. Both spontaneous bleeding and bleeding after an injury or surgery may result from this. Numerous clotting proteins found in blood can help to stop bleeding. Blood clotting is impaired by a rare disorder called hemophilia. It happens as a result of the body not producing enough of a protein called a clotting factor. Clotting aids in stopping the bleeding after an injury or accident. In the absence of coagulation, bleeding may be excessively simple or prolonged. There is currently no known cure for hemophilia, despite the fact that treatment for those with the condition has significantly improved over the past few decades.

Answer:
Explanation:
metal can become magnetic if they have many spinning electron. When the majority of atoms spin in the same direction the strong magnetic field is produced the direction of electron spin determine the direction of magnetic field

Explanation:
This is because the acceleration due to gravity on the moon is a third of that on earth
