Answer:
when G1/S cyclin-CDK is activated. Expression of G1/S cyclins is regulated by E2F proteins
Explanation:
I've found this on Google
Commitment to cell division occurs at Start when G1/S cyclin-CDK is activated. Expression of G1/S cyclins is regulated by E2F proteins in conjunction with pRB proteins.. Mitogens stimulated cell division by increasing the amount of G1 cyclins.
You can infer that the birds once had a common ancestor but became separated. Mutations in copying their genes stacked and caused changes in the beaks so the birds could be more well off or better adapted in their new environment.
These secondary compounds are primarily adaptations that is inhibit herbivory.
Option D is correct.
What is meant by herbivory?
Herbivory may be a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that prey on autotrophs in general are known as primary consumers. Herbivory is typically limited to animals that eat plants
What is the herbivory effect?
Herbivory can affect the expansion form of plants by terminating shoot growth and initiating branching and by affecting shoot-to-root ratios. Changes in survival, productivity, and growth of individual plant species affect vegetation structure and community dynasty.
<h3>Why is herbivory important?</h3>
Herbivory can have substantial impacts on habitat health, the structure and variety of plant and soil invertebrate communities and the productivity of economically important crops. The positive impact of herbivory is widely debated within the scientific literature.

Answer: Ectotherms depend on external heat sources. Their body temperature changes with the temperature of the environment. Endotherms generated heat internally to maintain body temperature.
