When a cold front happens when speaking gusty, there is a sudden drop in temperature, and there is heavy rain. When warm front approaches, The air becomes noticeably warmer and more humid than it was before.
<em>When water is abundant:</em>
-Temporal regulation of stomata is used:
Open during the day
Closed at night
- At night, there is no photosynthesis, so no demand for CO2 inside the leaf.
- Sunny day = demand for CO2 in leaf is high = stomata wide open.
- As there is plenty of water, plant trades water loss for photosynthesis products.
- If the leaf's CO2 concentration is low, the stomata will stay open to continue fueling photosynthesis.
- High temperatures will also signal stomata to close.
- When limited water is available in the soil, plants try to prevent water loss.
The answer is "because water is produced as a by-product"...the word dehydration should also be a major clue because that means water loss.
I would say energy myself, and this is because energy plays a key role in all of these. With trophic levels energy is being transferred amongst the levels. Food chain's is a map of how the energy is passed along the chain. Food web is a web of how energy is transferred, and this is why I would say energy is a keyword.
Answer: I thought I have answered this question before. Yes emzymes are sensitive to PH and temperature.
Explanation:
if the temperature is above 60 - 70 degree celcius, it looses it's ability to catalyse as such emzymes are kept within the normal body temperature to function effectively. Emzymes are also sensitive to PH changing the pH of its surroundings will also change the shape of the active site of an enzyme and also changing the pH will affect the charges on the amino acid molecules.
