it is often useful for scientists to study a population of cells that are all at the same stage of the cell cycle. for example,
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. another method involves gently shaking culture flasks and harvesting the cells that release from the substratum. in what stage of the cell cycle are these cells most likely to be?

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
The tree absorbs light energy from sunlight, converting the light energy into chemical potential energy stored in chemical bonds. The tree uses this energy to build leaves and branches and fruit. When the apple hits the ground, kinetic energy is transformed into heat energy.
