Natural selection is basically when organisms with the best traits survive and pass on their good traits to their offspring so that they will adapt easily and survive. Organisms who do not have ‘good traits’ that help them adapt and escape predators will be killed or eaten before they reproduce.
So in the end, natural selection is a form of evolution that allows the ‘fittest’ animals to survive and reproduce, while weeding out the unfit.
It is transplanted routinely to treat a variety of blood and bone marrow diseases, blood cancers, and immune disorders. More recently, stem cells from the blood stream (called peripheral blood stem cells) and umbilical cord stem cells have been used to treat some of the same blood-based diseases
Answer:
speed up the rate of virtually all of the chemical reactions that take place within cells.
Answer:
200 ATP molecules
Explanation:
Yeast is a fungus that undergoes fermentation instead of cellular respiration when there is an absence of oxygen. In the fermentation process undergone by yeast, which produces an alcohol as product (alcohol fermentation), two (2) ATP molecules are produced as net ATP.
However, if a yeast cell undergoes fermentation and uses 100 molecules of glucose, the yeast cell will generate a net ATP of 2 × 100 molecules = 200 molecules.
