Answer:
Proteins are macromolecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs
Too bad there's not the options, but the answer must be the hydroxyl and carbonyl group.
The solubility of sucrose in water as well as organic solvents is very high. In non-aqueous solvents is generally lower. On the other hand, sucrose is not soluble in nonpolar solvents. This solubility in the polar solvent as well as the water is due to the hydroxyl (-OH) and carbonyl (-C = O) functions creating hydrogen bonds with the solvent molecules making it easier to dissolve.
The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane
According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.
The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.
Components of the cell membrane include:
• Phospholipids – Form a bilayer
• Cholesterol –improves stability and reduce fluidity
• Proteins –integral (transmembrane) or peripheral
• Sugars-usually attached to proteins.
Answer:
The Carbon Cycle. The Earth's Carbon Cycle is the biogeochemical exchange of carbon between the earth's five main physical “spheres”—atmosphere, biosphere, pedosphere, hydrosphere and lithosphere.
