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.
This is in contrast to non-renewable fuels such as natural gas, LPG (propane), petroleum and other fossil fuels and nuclear energy.Renewable fuels can include fuels that are synthesized from renewable energy sources, such as wind and solar.hen this process draws its power from renewable energy sources like wind turbines or photovoltaic cells, the production requires little consumption of non-renewable resources. Hydrogen fuel, when produced by renewable sources of energy like wind or solar power, is a renewable fuel.
