Follicle-stimulating hormone (FSH) is a glycoprotein hormone found in humans and other animals.It is synthesized and secreted by gonadotropes of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body.SH is a 35.5 kDa glycoprotein heterodimer, consisting of two polypeptide units, alpha and beta. Its structure is similar to those of luteinizing hormone (LH), thyroid-stimulating hormone (TSH), and human chorionic gonadotropin (hCG).
They are formed from broken down animals and plants that died a very long time ago. ] . Fossil fuels are non-renewable [non-renewable: A resource that cannot be replaced when it is used up, such as oil, natural gas or coal. ] because they will run out one day.
Although fossil fuels are continually being formed via natural processes, they are generally considered to be non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made.ossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms.
