Because less animals means less energy that can be used.

When food is consumed, most of the energy goes to the organism that eats it. And so, as another organism eats the other, it will only get a small portion of the energy that is left and so on.

denis-greek [22]

Answer:

The correct answer is - 2 genes.

Explanation:

The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:

suppose there are only two gene - TT dominant over tt and CC dominant over cc

then the cross would be - RRCC - rrcc

gametes - RC and rc

Cross F1: RrCc

Self cross in F2:

offspring by Punnet cross are:

RRCC  -->1/16  

RRCc,  RrCC .---> 4/16

RrCc, RRcc, rrCC--->6/16

rrCc, Rrcc--->4/16

rrcc ----> 1/16

thus, the correct answer is 2 genes

I am trying to determine reactants going into the electron transport chain. Is this right?
irina1246 [14]

Answer:

Yes, this is correct.

Explanation:

  • In each glycolytic pathway, glyceraldehyde 3-phosphate dehydrogenase produces 1 molecules of NADH as a result of reduction of NAD+.
  • Pyruvate dehydrogenase converts pyruvate to Acetyl CoA producing 1 molecule of NADH per pyruvate oxidized.
  • In Kreb's cycle, isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, and malate dehydrogenase reactions produce 1 molecule of NADH each. Furthermore, succinate dehydrogenase reaction produces a single molecule of FADH2 per FAD reduced.
  • Since, we began with 2 molecules of glyceraldehyde 3-phosphate, we  multiply the above figures by 2 and get a total of 10 NADH and 2 FADH2.
