Answer:
Type O- blood is the universal donor
Type AB- blood is the universal recipient
Answer;
A. if water moves into a cell by osmosis it is moving into an area of higher solute concentration.
Explanation;
-Movement of water from a dilute to a more concentrated solution through a partially (semi) permeable membrane that allows the passage of water but not solute molecules is called osmosis.
-Osmosis describes the movement of water (not the solute) across a selectively permeable membrane until there is an equal concentration of water and solute on both sides of the membrane.
Receptors in the cell surface bind to their specific ligand and thus trigger a signaling pathway such as a phosphorylation cascade.
<h3>What are cell receptors?</h3>
Cell receptors are specific proteins within the cell membrane of the cell that binds to ligands and trigger signaling pathways, thereby mutations in the receptor sequence or problems associated with this process may produce a failure in the pathway.
The possible results of cellular response that could be disrupted include the inactivation of the signaling pathway, which might be a cause of a change in the production of a transcription factor that shapes gene expression patterns.
The types of ligands depend on the cell receptor (i.e., ion receptors, GPCRs, enzyme-based linking).
In conclusion, receptors in the cell surface bind to their specific ligand and thus trigger a signaling pathway such as a phosphorylation cascade.
