Answer:
Because different cells are under different pressure. The most frequently replaced cell would be skin cells while on the opposite scale we have neurons. Skin is under constant pressure so we have to replace it as quickly as possible where as neurons must be replicated only once so we can maintain a stable brain.
Explanation:
An instrument used for measuring rate of Transpiration occurring from lower surface of leaf.
This is my opinion but based on the connotations of the words I would say that an observation is the information you gather from something indirectly, like you're not asking someone a specific question. For example, if I see that someone eats everything on their plate except their carrots, i can observe that they do not like carrots.

I believe it would be a because your body is stimulated to drink water when you are dehydrated
Answer:
Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre. Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. A chemosensltive area is situated adjacent to the rhythm centre to make necessary adjustments in the respiratory process. Receptors associated with aortic arch and carotid artery also can recognise changes in CO

and H+ concentration and send necessary signals to the rhythm centre for remedial actions. The role of oxygen in the regulation of respiratory rhythm is quite insignificant.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
