Enzymes can be best described as catalysts in living systems. This is because enzymes accelerate chemical reactions without being used up in the process.
Adults spend about 20% of their time asleep in rem sleep. Hope this helped, have a great day! :D
Answer:
a. Oxygen performs an essential role in the mentioned microbial cell in a manner that it takes part in the procedure of glycolysis, Krebs cycle, and electron transport chain, which eventually assists in the production of energy from food substrates and this generation of energy helps the cell to survive.
In the existence of oxygen, sugar gets dissociated through glycolysis to generate pyruvate, which again in the existence of oxygen is transformed into acetyl CoA. This moves into the Krebs cycle and gets dissociated to water and carbon dioxide generating ATP through ETC. This generation of ATP helps the cell to survive.
In low oxygen surrounding or in the absence of oxygen, some of the aerobic microbes can switch their respiratory pathway and carry on the process of fermentation and anaerobic respiration to produce energy and thrive. However, the mentioned microbial cell, which when it comes in contact with the low oxygen environment cannot carry out fermentation process and would die eventually.
b. This organism can be classified as obligate aerobes as they always need oxygen and do not possess the tendency to carry out the process of anaerobic respiration or fermentation under the absence of oxygenic environment.
Answer:

So I think it's C
4 cells would be created after meiosis and each cell would have 7 chromosomes.
<h3>Meiosis</h3>
Meiosis is the division of non-vegetative cells. It is a reductional division during which the ploidy level of the parent cell is halved in the daughter cells.
Thus, a cell with 2n = 14 that undergoes meiosis will produce daughter cells with n = 7.
Usually, 4 daughter cells are produced at the end of meiosis.
