Glycolysis uses 2 ATP and produce 4ATP. So the net gain is true.
Oxygen is used in the Electron Transport Chain as the final electron recipient from complex 4 cytochrome a₃.
Explanation:
Glycolysis is the process which is common in all forms of respiration where glucose is metabolized into pyruvate. This process is very essential to continue the next steps of different respiration. Glycolysis requires 2 molecules to process substrate level phosphorylation to convert glucose to glucose 6 phosphate and fructose 6 phosphate to fructose 1, 6 bisphosphate. But it produces 4 ATPs. Thus net gain is 2ATP.
In ETC, the hydrogen carriers NADH and FADH gives off the hydrogen to reduce the complex 1 and 2 respectively and itself gets oxidized. Thus the electron given off is transferred between 4 complexes to finally give off to oxygen to form water.
The answer is directional selection
It is the mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. The advantageous allele increases in frequency independently of its dominance relative to other alleles; that is even if the advantageous allele is recessive, it will eventually become fixed, changes the average value of a trait. Occurs most often under environmental changes and when populations migrate to new areas with different environmental pressures.
The most important difference between primary and secondary
groups is that, primary groups are being referred to a family in which every
person has while the secondary group is being referred to the society or the
sociology class in which every person partakes to.This group has to do with the relationships that exist
amongst them.
Answer:
Explanation:
You can get 1/4 tortoise female; 1/4 black female; 1/4 yellow male; 1/4 black male.
IT IS NOT possible to obtain a tortoise-shell male primarily because to have tortoise shell one has to be heterozygous. In case of males, they are hemizyogous so they only get one chromosome with the gene because they have XY and we know this disease is linked on X chromosome because different combinations give us different colors.
I say they are hemizygous because For example, most of the genes of the X chromosome and Y chromosome in human males are hemizygous since males have only one X chromosome (and one Y chromosome) (unlike females that has two X chromosomes).
