Answer:
See details below
Explanation:
We know for sure that PK2 activates PK1 in a significantly signaling pathway. This is mainly because PK1 is permanently activated as a independent response which is observed in the status of PK2, by indicating that PK2 is fully activated downstream of PK1.
In the case that based on observation and experience, a setup were modified in a such a way PK1 was mutationally inactive and PK2 carried an activating mutation, we would not find any response observed since PK2 would not be able to activate PK1. The most importantly is that the logic is whether you discuss that PK1 activated PK2, I responded to this question part mainly based on this sequence.

a) Nitrogen is an essential part of biological molecules such as proteins and nucleic acids (DNA).
Explanation:
- Nitrogen is an essential component of building blocks of life that are DNA, RNA and Protein. It is also needed for the production of chlorophyll. We can say there would be no life without nitrogen.
- Air we breathe is 78% nitrogen but that is in inert form (N2) and we can't use it.
