Viral infections are common in babies and children and often cause a minor rash of the skin. These rashes are usually harmless and will go away on their own. Different viruses can cause different rashes, and sometimes different viruses can cause rashes that look the same.
receptors for both lipid-soluble and lipid-insoluble hormones are found within the cell and usually within the nucleus. receptors for lipid-soluble hormones are on or in the cell membrane, whereas receptors for lipid-insoluble hormones are inside the cell.
Lipid soluble hormones... require a membrane receptor protein to enter the cell. B) diffuse through the cell membrane. enter the cell through active transport. D) work as ligands on the surface of the cell membrane. require specific gates to pass through the cell membrane.
