Plants typically absorb carbon dioxide and give off oxygen during the day. However at night this tends to be the opposite and plants will absorb oxygen and give off carbon dioxide. Please expalin:
A) What are the names of 2 processes are happening in plants that cause this
B) when each process happens
C) why each process happens when it does
(this is science)

It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out

Explanation:

process: respiration, and photosynthesis

when: as soon as sun rises

why: Plants and animals, in turn, convert the food compounds by combining it with oxygen to release energy for growth and other life activities

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
