Mitosis is important for a number of reasons. It's a form of reproduction for some organisms that reproduce asexually, it's needed for growth and development, and also for the repair and replacement of cells. If we didn't do mitosis dead cells wouldn't be replaced, and that would cause some massive problems. For example, if we weren't capable of doing mitosis and you cut your hand, the cut wouldn't heal up because the cells wouldn't be getting replaced.
Question 4
Which of the following would be considered a form of active transport?
o the movement of oxygen molecules from high concentration in the blood to low concentration in the cell.
O the movement of carbon dioxide from high concentrations in the cell to low concentrations in the blood.
o the movement of glucose into the cell down its concentration gradient,
o the movement of sodium atoms from low concentration in the cell to higher concentrations outside the cell.
Hey!
So for the first answer, neither Fungi or Bacteria contains the given protein.
For the second answer, I'm pretty sure that I think that Fungi can reproduce asexually or sexually, while Bacteria can only do it asexually.
For the fourth answer, bacteria can be both, but fungi scavenges nutrients from dead organic material.
That leaves answer three, which is true.
I hope this helped! I'm sorry if I'm wrong.

Answer:
A. If the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt."
C. After about 90 seconds of intense exercise, the muscles become depleted of oxygen, and anaerobic respiration can no longer function to produce ATP, resulting in "oxygen debt."
Explanation:
There are two sources of carbohydrates in the human's body for energy (ATP) production. 1) Creatine phosphate and 2) Glycogen. Creatine phosphate metabolizes easily and yields ATP quickly. Whereas glycogen is stored form of carbohydrate which yields energy more slowly. Therefore, initially, our bodies use creatine phosphate and then shift to glycogen. Within 60-90 seconds, the creatinine phosphate in the body is mostly utilized and then energy is produced by the use of glycogen in aerobic pathway. During areobic pathway, oxygen supply is sufficient and per cycle, it produces 32 molecules of ATP. However, when oxygen supply is limited or absent, the body will metabolize glycogen to lactic acid via fermentation and produce only 2 molecules of ATP.
Now consider the example: Kenny hikes all day at a steady pace therefore the supply of oxygen is sufficient for aerobic cellular respiration for ATP production. In this scenario, the oxygen debt is minimal and Kenny relies on aerobic respiration pathway to obtain energy. On the other hand, Janelle runs fast (100 meters in 13.5 seconds) and her cellular respiration would be on the compense of aerobic pathway initially which will be shifted to anaerobic pathway after the supply of oxygen is reduced/minimum. Janelle will heavily rely on the anaerobic pathway because running fast needs energy which cannot be provided via aerobic pathway easily. Therefore, Janelle's body will produce lactic acid and suffer from oxygen debt.
