Answer: B (GTP serves as the energy input for AMP synthesis from IMP)
Explanation:
In the de novo synthesis of purine nucleotide, IMP represents a branch point for purine biosynthesis. IMP can be converted to either AMP or GMP.
The formation of AMP from IMP requires GTP; similarly formation of GMP requires ATP. The conversion of IMP to either AMP or GMP is highly regulated – AMP and GMP inhibits their own formation by feedback inhibition of adenlyosuccinate synthetase and IMP dehydrogenase.
The sweet pea plants having a diploid 2n chromosome number of 14 produces F1 offspring with 14 chromosomes by the process of fusion of gametes each having n number of chromosomes.
<h3>What are diploid organisms?</h3>
Diploid organisms are organisms having two copies of each chromosome or 2n number of chromosomes
Diploid organisms undergo meiosis to produce haploid cells having n chromosomes.
Two haploid cells from each parent combine to produce offspring with 2n number of chromosomes.
Therefore, the sweet pea plants having a diploid 2n chromosome number of 14 produces F1 offspring with 14 chromosomes by the process of fusion of gametes with n number of chromosomes.

Answer:
b. Feedback response
Explanation:
Homeostasis is the ability of the system to preserve a constant state despite external inputs. Homeostasis requires the constant monitoring of internal environmental conditions in order to keep the balance of the system. Conversely, a feedback response enables to maintain a change observed in the internal conditions of a given system (for example, a living organism). This change is regulated by the interaction among different elements in the system including effectors, sensors and stimuli, which work together to maintain the feedback state.
Cell walls, which are found in plant cells, maintain cell shape. Some animal cells dont need to maintain shape. Such as muscle cells, they are constantly moving.
