Answer:
B
Explanation:
facilitated diffusion requires an ATP, which means it DOES take up energy
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:
They would all have a chance of getting it because most people who have hemophilia are born with it and It almost always is inherited (passed down) from a parent to a child. But its unlikely for the dad to get it.
Explanation:
Try researching the discovery of microscopes and their impact on scientific discoveries, including cells!!!
