Answer: heres the 3 main functions.
Explanation:
membranes have three primary functions 1) they keep toxic substances out of the cell 2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment and 3) they separate vital but incompatible metabolic processes conducted within organelles.
Answer:
Withering is a process in which a rock gets broken down into small and large fragments which are displace other location by the action of wind, water and ice. There are three types of withering: mechanical ,chemical and biological. Mechanical withering is a process which brings changes into physical structure of rocks like large rocks are converted into small rock. Chemical withering is a process which brings changes in the chemical composition of rock. This withering process can change minerals content in the rock. Biological withering is a process in which living beings uses rock for their survival like plants, animals and microbes causes disintegration of rock.
Highly withered and unwithered rock can be distinguished by following characteristics:
1. Physical structure: There will be no change in the structure of unwithered rock but structure of highly withered rock will change after the withering process.
2. Chemical composition: The withering process will remove surface and internal minerals present in rock. In unwithered rock the surface and internal mineral composition will remain unchanged but in highly withered rock the surface and internal minerals present in rock will be removed, which change the overall chemical composition of the rock.

Answer:
Linings of hollow organs
Explanation:
Smooth muscle cells are usually found in the lining of hollow organs such as all arteries and veins, wall of stomach, uterus, urinary bladder, digestive system etc. The cells of these linings are spindle shaped and consist of a nucleus at the center which lacks striations.
They work as a housekeeper and are under involuntary control except the heart. They lack striation because of irregular arraying of actin and myosin filament along the length of the cell.
