Answer:
c. RrMm x RrMm
Explanation:
A dihybrid genotype is the one that is heterozygous for two genes. Hence, a dihybrid cross is a cross between two individuals that are hybrid for alleles of two different loci.
Among the given examples, the cross RrMm x RrMm is a dihybrid cross. Here, both given genotypes are heterozygous or hybrid for two loci (both genotypes have one dominant and one recessive allele for both the genes under study, R and r; M and m).
This cross explains the inheritance of two loci or two genetic traits. Hence, it is an example of dihybrid cross.
The salt most likely will raise the boiling and freezing points of the solution slightly.

Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
<span>Vasopressin, or the other name Anti Diuretic Hormone (ADH), has the action of causing the opposite (anti) of a diuretic. I.e., it causes the body to retain sodium, thus retaining water. This has many physiological effects, the majority of which focus around enabling the body to maintain homeostasis when water intake or hydration levels drop.</span>
