<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.
A one in one thousand one chance
Answer:
A plant without fertilizers
Explanation:
A control group is a group where no changes are made so that it can be compared to the group that was tested on, or the independent test variables, to see the difference. So, a plant without fertilizers would be the answer.

Answer:
The correct answer is - natural selection process does not move simply to an optimized endpoint.
Explanation:
Natural selection is a process of evolution that helps in evolving populations that are adapted to successfully reproduce and survive according to the environment.
Natural selection does not march simply to an optimized endpoint. Natural selection works upon individual organisms that have advantageous characteristics in specific environments. If the environment changes the advantages can become disadvantageous.
Thus, the correct answer is - natural selection process does not move simply to an optimized endpoint.
