Answer:
b. the rate at which the mRNA is degraded.
Explanation:
DNA is transcribed into mRNA which then joins ribosomes present in the cytoplasm to serve as a template for protein synthesis. Regulation of gene expression occurs at several levels.
One such regulatory mechanism is the stability of mRNA and the rate of its degradation which in turn affects the availability of template for the process of protein synthesis and thereby keeps a check on the total amount of protein being formed in a cell.
For example, a very short life span of bacterial mRNA (few minutes) allows them to regulate the pattern of protein synthesis quickly in response to the changes in surroundings.
Photophosphorylation is a process that occurs during photosynthesis in plants. It is the conversion of ADP (Adenosine Diphosphate) into ATP (Adenosine Triphosphate) using light energy. ATP (Adenosine Triphosphate) is the energy currency of life of all living organisms. Without ATP, cells will not be able to perform their proper functions.

Through the process of phosphorylation, light energy is used to create electron donors and electron acceptors that move spontaneously through the process of electron transport chains. </span>
Only 1- the experiment can not show a cause and effect relationship if there are more than one factors contributing to the outcome.
Answer:
The three domains are the Archaea, the Bacteria, and the Eukarya.
Explanation:
Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
Because as natural selection occurs and species mate and create offspring this leads to a change in DNA which can lead to new species or evolutionists versions of that species
