Answer:
The answers are :
Explanation:
A. Hidrolyisis- deficient RAS mutant :1. Continual activation of the MAP kinase pathway even in the abscence of signaling molecule, 5.Change in the expression of genes in the absence of the appropriate signaling molecule
C. High GDP affinity RAS mutant: 2.Failure to activate MAP kinase pathway following ligand binding to receptor kinase, 6. Target genes are not expressed even in the presence of signaling molecule
B. Neither: 3. Failure of receptor kinase to dimerize in the presence of ligand, 10. A continuously activated receptor in the absence of ligand
Aldosterone stimulates the reabsorption of Na+ and secretion of K+ in the the kidneys. Aldosterone is classified as a steroid hormone that is being produced and secreted in the adrenal cortex. It stimulates the reabsorption of these ions by increasing the activity of the sodium and potassium pumps and the leakage channels of the sodium and the potassium ions. This hormone would activate the electrogenic channels of these ions located in the apical membrane increasing the synthesis of the channels. The secretion of this hormone is being stimulated by the low plasma sodium ion concentration, high plasma concentration of the potassium ions and the angiotensin 2.

Cloud 1 is a cumulus cloud which is large and carries storms.
Cloud 2 is cirrus cloud because they cover the sky all of the way and can bring light rain, sleet, or snow.
Answer:
The structures that are found in both eukaryotic and prokaryotic cell are-
Explanation:
ribosomes, DNA, cytoplasm.
Ribosomes are biomolecular complex, composed of RNA and protein and act as the site for protein synthesis in all the cells of the living organisms.
DNA (deoxyribonucleic acid) is considered.
