Question 1 ) muscle cell maintains homeostasis is not an example of the <span>intracellular communication.
Question 2 ) </span>intracellular receptor goes into action <span>When non-nerve cells become involved in response to signals.</span>
Explanation:
if solute is 43% inside the cell then water is 57% (100%-43% = 57%)
outside; 100% - 60% = 40% water
it is hypertonic because water concentration is high inside the cell than outside, hence water flows to the outside of the cell.
So the simple answer would be evaporation is slow and can only occur through the surface of a liquid and it cools it down, while boiling is fast and produces bubbles ( evaporation does not ) and it occurs throughout the liquid and doesn’t cool it down. A similarity between the two would be water vapor is given off
Both the processes of evaporation and boiling result in a change from liquid to vapor.
hope this is what u we’re looking for and this helps !! :)
Answer:
The modified hemoglobin with free imidazole cannot be expected to show cooperativity in oxygen binding. The movement of iron ion takes place up in the plane of heme when binding of one subunit of hemoglobin takes place with oxygen. One of the iron's and oxygen's axial ligands comprise the proximal histidine's imidazole ring.
With the movement of iron into the hemoglobin ring, the pulling of proximal histidine takes place along with it. Therefore, when binding of oxygen takes place with one subunit, a modification also takes place in the intersubunit associations, this also comprises displacement of the alpha helix. This phenomenon plays an essential role in modifying the hemoglobin's tensed state to the relaxed state. The withdrawal or mutation of the imidazole ring from the histidine residue does not further permit the cooperative binding as it is not associated physically with the alpha-helix.
