Osmosis of Water Across the Membrane. Osmosis is the tendency for water molecules to move from where there is a higher concentration to where there is a lower one. ... The cell membrane helps to regulate and slow down the flow of water into the cell. This is yet another way that the cell membrane helps maintain homeostasis
Answer:
D. Cell signalling which is released by one type of cell and acts upon a different cell
Explanation:
According to this question, adrenal cells near the kidney releases an hormone called ADRENALINE, which causes the cells of the heart to beat faster. This is an example of CELL SIGNALLING because chemical signals released by adrenal glands causes/triggers a response in the heart cells.
The chemical signal released by the adrenal cells is the ADRENALINE HORMONE, which induces a response in cells that are different from the cells of release (adrenal cells).
Answer:
The more newly synthesized peptides had greater levels of radiolabeled H
Explanation:
Using immature red blood cells (reticulocytes), Dintzis showed that polypeptide chains of hemoglobin were created from N-terminal to the C terminus during translation. Dintzis labeled with radioactive amino acids that were being actively translated, subsequently digested the translated proteins with trypsin and finally determined the amount of tryptic protein fragments. From this experiment, Dintzis observed that the radioactive products were concentrated in the C-terminus (i.e., labeled amino acids appeared first in the C terminal tryptic peptides), thereby showing that the direction of protein synthesis is from the N terminus to the C terminus.
