Skin colour in humans is determined by more than one gene pair, whereas Rh factor in blood is controlled by one gene pair. Which

would show more variability in the human population? Why?

Answer:

Well...

Explanation:First of all skin color is determined by how much melanin you have and the one thing that would show more variability in the human population is probably the one that uses less genes, because of how we come from only two genes which makes us different.

Why do enzymes act upon energy of activation
riadik2000 [5.3K]

In the presence of an enzyme, the Activation energy is lowered. thus the reactions reaches the activation energy and the reaction is initiated faster and therefore completes faster than the reactions without enzymes. Enzymes lower activation energy, which allows a reaction to occur at a faster rate.

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.
