<span>A heterozygous individual is if a mutation occurs in just one copy of the gene.
If both copies of the gene are mutated than the individual is homozygous</span>

Answer:
the correct answer D please give me brainlyest
Answer:
The correct answer is- facilitated diffusion
Explanation:
In facilitated diffusion molecules(solutes) are moved from area having a high concentration of solute towards the area having low solute concentration through a semipermeable membrane with the help of specific proteins is called facilitated diffusion.
As molecules move along the concentration gradients so no energy consumption is required in facilitated diffusion. Transport proteins like channel proteins are used to transport the molecules across the cell.
The rate of transport is higher in facilitated diffusion than simple diffusion. Polar and charged molecules can be diffused by facilitated diffusion.
The mitochondria is a double membraned organelle, the inner of these membranes is invaginated to form structures called cristae. The fluid inside is called the mitochondrial matrix. The mitochondria has a pivotal role in the creation of ATP in aerobic cellular respiration. Glycolysis occurs outside the mitochondria, producing pyruvate and ATP, the pyruvate endures the link reaction on its way into the mitochondrial matrix and turns into acetyl co enzyme A. This acetyl group is used in the matrix in what is called Krebs cycle, where the oxidation of acetyl groups is coupled with the reduction of hydrogen carriers. The products of Krebs cycle are then transported to the electron transport chain on the cristae where the reduced NADH and FADH are then oxidized. The remaining hydrogen electrons are transported down the chain where an oxygen molecule is reduced to water. Chemiosmosis also occurs at the electron transport chain, in which hydrogen protons move down the concentration gradient (from the inner mitochondrion membrane) through an ATP synthase where ATP is generated. The multiple folds inside the mitochondria which are the cristae, mean that there is plenty of surface area for cellular respirations to occur at.
