The answer is B :),this sentence has to be longer LOL
Answer:
Man's genotype: XᴮY
Woman's genotype: XᴮXᵇ
Daughter's genotype: XᵇXᵇ
The daughter is not the man's child.
Explanation:
Color blindness is a sex-linked trait caused by a recessive allele located in the X chromosome (Xᴮ=normal vision; Xᵇ-color blind).
Women have two X chromosomes, while men have an X and a Y chromosomes. For that reason, women need to have two recessive alleles to be color blind, while men only need one Xᵇ to be colorblind.
Since the man has normal color vision, his genotype would be XᴮY.
If the daughter is her father's, she would have inherited his dominant Xᴮ allele, so she would have normal vision. However, she is colorblind, so her genotype is XᵇXᵇ. She is not the man's daughter.
The mother also has normal color vision, but her daughter inherited a recessive allele from her, so her genotype is heterozygous XᴮXᵇ.
The organelle that provides evidence for this theory is the mitochondria and the chloroplast.
<h3>What is the endosymbiotic theory?</h3>
The endosymbiotic theory is the theory which describes how the eukaryotic cells arose from simple prokaryotic cells.
In the endosymbiotic theory states that when two prokaryotic cells with several abilities came together, one engulfed the other and existed in a symbiotic relationship that enabled the cells to meet their needs for survival an growth.
The mitochondria and the chloroplast provides evidence for the endosymbiotic theory.
In conclusion the endosymbiotic theory describes how eukaryotic cells arose from simple prokaryotic cells.

Answer: B. Water breaks down into oxygen molecules for respiration.
Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.
This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.
