If there is an environmental or selective pressure it will contribute to the evolution of an organism by giving an adnantage to the organisms of a population who have a trait which allows them to survive that change. The advantageous genes will be passed on and the number of organisms with the desirable feature will increase over time, however the number of organisms that lack the characteristic will decrease over time. This is evolution by natural selection.
Because you need your legs to carry your whole body, so, essentially, your legs have to have bigger bones and muscles.
<span>Asxual resproduction takes place by only one organsim. There is no fusion, no chnage in the chromosome numbers. Thus, an asexual reproduction produces offspring by the process of mitosis, where each cell divides and form two daughter cells, which are similar to each other.</span>
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.
