Explanation:
Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source.
In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes. So, our cells carry 46 total chromosomes, in two copies. However, each homologous chromosome can provide a different version of each gene. Two versions of each gene create more variety, lower the detrimental effects of negative mutations, and generally stabilize a population.

Answer:
Number of protons plus the number of neutrons.
Explanation:
Most of an atom's mass is in its nucleus. The nucleus is made up of protons and neutrons.
The correct answer is option A
A person that is having an allergy with pollen grains should take antihistamines.
When there is an allergic reaction in the body then the body releases histamines which evokes immune response.
As a result of this the person starts sneezing, runny nose, hives et cetera.
So, one should take antihistamines to prevent the action of histamines on the body.
The best answer would be:
A. DNA is being transcribed into mRNA.
If you'd like to know why:
In the image shown, you can see the <u>BLUE </u>strands and the <u>RED </u>strand. The Blue strand is DNA and the Red strand is mRNA. What is happening in the picture is TRANSCRIPTION. It is the process of making an RNA copy of the DNA strand to create proteins based on the DNA strand.
The <u>GREEN</u> blob is most likely RNA polymerase. Its job is to synthesize or make a complementary RNA strand of the DNA by assembling nucleotides to form an RNA strand based on the DNA template.
