The skeletal system since the brain is apart of the skeletal system.
Water vapor , you need a liquid to have acid rain-(rain is water btw)
When cells become unable to regulate the cell cycle, tumors can develop.
When the organism dies in a moist or wet area the organism gets covered in mud and the mud hardens like a rock.
Explanation:
-the specific binding of a region of the protein to solutes or a substrate
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers or function as receptors.
These include receptor proteins that bind specifically to molecules called lingands; some also use channels which respond to chemical signals by modifying solute-specific regions that aid in regulating ion exchange, through the hydrophobic layer of the plasma membrane.
