Because freezing will often burst the cell walls and destroy tissue. The crystals of ice are very sharp and hard to control AFAIK. Note what happens to a banana or many types of fruit after you dethaw — it becomes all mushy and not of the same structure, fiber and cell form as before, like a bad beam up in Star Trek.
<span>A nerve is a bundled unit of nerve fibers located in the ide peripheral nervous system of the brain and spinal cord, connecting various parts of the body. These are the axons and are cable-like bundles which provide a way for all the electrochemical signals. They are of 3 types: afferent, efferent and mixed nerves. </span>
For many common cancers, such as breast cancer, bowel cancer and prostate cancer, radiation therapy is highly effective in reducing the risk of cancer recurrence after surgery or helping the surgery be more successful.
Some of the organisms have evolved in such a way that they remain inactive when the predator populations are active.
Adaptive theory of sleep suggests that the prey population prefer to sleep when (in this case, at night) the predators are most active. The prey population use this time in taking rest and restoring energy for other works. As the prey population is inactive and remained protected in safe places, they are less likely to be predated.
Hence, the correct answer is adaptive theory of sleeping.
The study of how food interacts with genes is known as Nutritional Genomics, that encompasses nutrigenomics, which explores the effects of nutrients in the genome, proteome and metabolome, as well as nutrigenetics, whose main goal is to elucidate the effect of genetic variations on the interaction between diet and disease.
