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:
b. The overall amount of energy in the bowl will neither increase nor decrease.
c. The ice cream will increase in energy.
Explanation:
b. The total amount of energy in the container will not increase or decrease. Since the energy is transferred from one element to another, the energy that dissipates is negligible.
In this case the energy of the pie is transferred to the ice cream, melting it.
c. The ice cream will increase in energy. As the heat is transferred from the pie to the ice cream. the movement between the particles of the ice cream increases, increasing its kinetic energy

One result of a loss of ground water would be that the freshwater on earth is 98 percent stored in the ground, therefore we would lose 98 percent of the very little amounts of freshwater we have
