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.
Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits.ossil fuel (primary non-renewable fossil) sources burn coal or hydrocarbon fuels, which are the remains of the decomposition of plants and animals. There are three main types of fossil fuels: coal, petroleum, and natural gas.
