The process, primary succession, would best describe the series of photographs when all of the topsoils were destroyed after the eruption. There is just one thing to remember about this, that the primary succession occurs on the land that has nothing and is the soil building process.
<span>All cells use oxygen to convert raw food products into energy they can use for health. In the process they make a bi-product which is carbon dioxide and waste material. If there was no cellular respiration the cell would die, because they would be lacking the oxygen needed for food conversion, and they would have no means of getting rid of their waste products.</span>
Answer:
Muscle cells can continue to produce ATP when oxygen runs low using lactic acid fermentation. However, this often results in muscle fatigue and pain. Many yeast uses alcoholic fermentation to produce ethanol.
Yeast food is sugar and its concentration affect yeast’s growth and activity. The process by which yeast metabolize sugar is called fermentation. A sugar concentration that is not very high (up to 3%), increase the fermentation rate. But, with over 3% sugar, the fermentation rate no longer increases. Above 6%, sugar actually decreases the rate because it begins to dehydrate the yeast cells. This effect is called crenation.
