Answer:
it’s more likely due the brown alele is dominant.
But it depends on the genotype, because she can be a carrier of the blue gene. In the simplest models of eye color, there are two genes involed (this is a simplified model).
Gene 1 there are two possibilities brown or blue. The brown version of the gene 1 is dominant over the blue one. Dominant means is if a least 1 of your copies is brown. then you will have brown eyes.
Gene 2. there are two possibilities, green or blue. Green is dominant over blue,
Answer:
oxygen
Explanation:
cells use to produce energy during cellular respiration
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain when they gain electrons.
As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water. Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur. Only oxidative phosphorylation uses oxygen directly, but the other two stages can't run without oxidative phosphorylation.).

I think it is beneficial for the brain to be connected to the contralateral side of the body because of the position and connection to the brain that our eyes have. Because light from the right visual fields strikes the left side of the eye and light from the left side strikes the right side of the eye, the connections allow visual information from both sides of the body to reach the brain.
