Answer
Most of these techniques, including microarray analysis and reverse transcription polymerase chain reaction (RT-PCR), work by measuring mRNA levels. However, researchers can also analyze gene expression by directly measuring protein levels with a technique known as a Western blot.

B
Explanation:
The more the soil absorbs water the less space there is for the soil to absorb more therefore it runs off.
If a cell’s nucleus has 55% adenine bases it also has 55% thymine bases, so the percentage of cytosine bases is 45% as same as guanine bases.
This is known as Chargaff's rule which states that DNA should have a 1:1 ratio of pyrimidine and purine bases (the amount of guanine should be equal to cytosine and the same thing with adenine and thymine).
DNA molecule globally has percentage base pair equality: %A = %T and %G = %C.
Since ponds are typically shallower than lakes, this allows more sunlight to reach pond plants than lake plants. By getting my sunlight, these pond plants can photosynthesize more efficiently.
