Answer: 26 chromosomes.
The diploid number is the number of chromosomes required for two
sets of copies of the organism’s genome ( this is the number of chromosomes in the cells except gametic cells). The organism's genome is represented as n, and the diploid number,as 2n (2 x 13= 26).
The answer is A because the subject is responding to something that is going on outside of it, if that makes any sense :)
Hope this helps! Have a great day!
The α-amino group of many amino acids is transferred to α-ketoglutarate to form glutamate, which is then oxidatively deaminated to yield ammonium ion (NH4+).
