Four friends were in the grocery store and they wondered which freezer is better at keeping the food cold; an upright freezer wi

th a door or a deep freezer without a lid? Read the following explanations and decide which person you agree with. a: Theresa: “The upright freezers are more efficient because they have doors to keep the convection currents circulating.” b: Kristen: “Actually the deep freezer has a thick layer of ice on the sides for an insulator and when you reach to the bottom things feel colder.” c: Brianna: “I think it is the deep freezer because the cold air stays in the bottom because cold air is denser.” d: Aaron: “The upright freezer is better because it keeps the cold air in. I have seen the cold air fall out when I open the freezer door.”

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon
stellarik [79]

Answer:

  1. Glycine
  2. Ribulose 1,5-bisphosphate
  3. 3-phosphoglycerate
  4. Glyceraldehyde 3-phosphate.
  5. Glucose
  6. Sucrose

Explanation:

The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.  

<u>Calvin cycle</u>

During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.  

During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.

During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.

<u>Cytosol: </u>

Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.

Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.

It is crucial that the process of mitosis is error free. This is because otherwise healthy cells can
kherson [118]

The correct answer is that it becomes cancer cells.  

Mitosis refers to the kind of cell differentiation, which leads to the formation of two daughter cells, and each comprising the same type and amount of chromosomes as the parent nucleus, generally of ordinary tissue growth.  

The process of mitosis should be error free as otherwise healthy cells can turn into cancer cells. Cancer is basically a disorder of mitosis, in this case, the usual checkpoints, which are monitoring mitosis are overridden or ignored by the cancer cells.  

Cancer initiates when a single cell is converted or transformed into a normal cell to a cancer cell and is generally taking place due to a modification in function of one of many genes, which usually work to monitor growth, like p53 gene or tumor suppressor gene.
