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.
I don’t see any labels, but remember that humans are a great example of a k-selected species. High rates of parental care leads to high survivorship of offspring, and thus negates the need to have large amounts of offspring.
R-selected species are quite the opposite. They produce large amounts of offspring at many intervals in an attempt to maximize survivorship, as they don’t have strong parental involvement with their young. Think of insects.
