The cell membrane is a biological membrane that separates the interior of all cells from the outside environment. It consists of a lipid bilayer with embedded proteins. The basic function of the cell membrane is to protect the cell from its surroundings. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules. In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.
Yes I think they are all examples of solids I hope this helps you
Answer: The elevation of an object is it's height above sea level. Sometimes elevation and altitude are using interchangeable, however, altitude is the vertical distance between an object and the earth's surface.
Explanation:
W. X. Y. Z = (1/2)(1/2)(1/2)(1/2)
= 1/16

Answer: a. express different genes.
Explanation:
The nerve cells is functional for controlling the coordination of the body, respond to the external stimuli, voluntary actions in the body. The muscle cells contract and relax to facilitate the locomotion.
All the somatic cells of a living being have the same genomic make up. However, completely differentiated cells of particular tissue lineages express distinct genes, as required so as to perform specialized functions in the body.
