It is often useful for scientists to study a population of cells that are all at the same stage of the cell cycle.
<h3>Why the discovery of cyclins and cdks was enabled?</h3>
The discovery of cyclins and cdks was enabled by studying frog eggs that divided synchronously after fertilization; extracts from the embryos were thus representative of the cell-cycle stage at which the extract was made.
Researchers have devised means to synchronize asynchronous populations of cultured cells. for example, serum starvation deprives cells of mitogens and blocks cells in the g0/g1 phase of the cell cycle.
Therefore, It is often useful for scientists to study a population of cells that are all at the same stage of the cell cycle.

Answer:
El efecto invernadero es el proceso por el cual la radiación de la atmósfera de un planeta calienta la superficie del planeta a una temperatura superior a la que tendría sin esta atmósfera. Los gases radiativamente activos en la atmósfera de un planeta irradian energía en todas direcciones.
Explanation:
Answer:
The answer is adaptation.
Explanation:
If we look at the example from the flower's point of view, this is certainly an example of adaptation because in order to pollinate more effectively and increase the chances of survival of their species, the flowers need the help of insect with their pollination so with time they've adapted their color so that they were noticable by insects.
