  <span>The cells all have different qualities. 
A plant cell will have a cell wall (the others don't have these) and so it will be kept in a rigid shape, unlike the others which are free to be blobby. Inside a plant cell, there is also a vacuole containing cell sap. The others don't have this. Plant cells also have chloroplasts, which look similar to mitochondria on a diagram. Chloroplasts contain chlorophyll, and this is used for photosynthesis. </span><span>

1.Mitosis is done by your body cells. What types of cells do not undergo mitosis?

Sperm cells and egg cells do not undergo mitosis. They undergo a different process of cell division called meiosis. The difference between the two types of cell division is that mitosis result in a replication of the parent cell or identical cells. Meiosis contributes to genetic variety, meaning the resulting cells are different from the parent cell in some way.

2.Describe  ways that mitosis is important for your body.

Mitosis is important for growth. Mitosis creates new cells as you grow. If you think about it, where do we get all the extra skin, longer bones, longer hair—they result from the division of cells which create new cells.

Another way it is important is in repair. When you get a cut for example, mitosis helps by producing more cells to repair the gash that was left. New cells fill in the part that was cut. Mitosis also helps with replacing worn out cells.

3. This illustration is trying to demonstrate something that mitosis is not. In mitosis, the cells that are created are identical.

The illustration shows that one type of cell produces a different type, but it is not the case with mitosis. The resulting cells of this type of cell division is identical or twins.

4.Mitosis is just one small part of the cell cycle! Describe what would occur if cells were in mitosis more than they were in interphase.

Interphase makes up most of the cell cycle, it makes up about 90% and mitosis occurs in 10% of the whole cycle.  If cells were in mitosis more than they were in interphase that would indicate an uncontrollable and rapid growth of cells and you can get cancer.

5.When cells are dividing, it is important to understand that they have to move chromosomes equally to both cells. Based on this illustration, describe what a chromosome is made of.

Chromosomes are condensed units found in the nucleus. There are 46 chromosomes each nucleus, or each cell. Chromosomes are made up of protein and DNA. DNA stands for deoxyribonucleic acid and it carries genetic information.

6. In humans, there are 46 chromosomes. They are duplicated during interphase, which in turn duplicates the DNA as well. Chromosomes are counted based on the number of centromeres. The number of chromosomes in living organisms or species differ from each other.

On a backpacking trip, Kenny hikes all day at a steady pace, covering 30 kilometers and burning 4000 Calories. At the school tra
olganol [36]

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.
