Long answer short- to reproduce cells.
Answer:
This nucleus then acquires <u><em>one </em></u>electron to become electrically neutral.
Explanation:
Fusion :It is nuclear reaction which two or more than smaller nuclei combines together to form heavy nuclear.
A neutron combines with proton in order to make heavy electron that is fusion reaction is taking place.
The overall charge in the nucleus will be +1.And in order to neutralize this positive charge the nucleus will acquire single electron to become electrically neutral.
Factories, cars and cigoretes.
All of these things are polluting the air cuasing it to heat up more which is cuasing global warming
Answer: a. Stomata open at Night
Explanation:
As a tactic to minimize photorespiration in warm regions, many water-storing plants such as cacti and pineapples modified its method of carbon fixation. This process is called Crassulacean Acid Metabolism (CAM), following the plant family Crassulaceae, in which it was first identified. In these plants, the stomata (singular, stoma), specialized openings in the leaves of all plants through which CO2 enters and water vapor is lost, open during the night and close during the day. This model of stomatal opening and closing is the opposite of that in most plants.
The continued presence of vestigial structures suggests that these structures do not have a great impact on fitness, like in the whale, because even with these structures, the whale has been able to survive and reproduce.
