The correct answer is the Phenotype.
The phenotypic ratio of 9:3:3:1 is the ratio associated with a dihybrid cross. It is a classical Mendelian example of independent assortment. It is a result of crossing two organisms that are heterozygous for two traits.
Answer:
Mitochondria and chloroplasts are much larger than prokaryotic cells.
Explanation:
According to the Endosymbiotic theory, all the components of eukaryotic cells were once individual prokaryotic cells which were able to function on their own.
The mitochondria was independent enough to perform aerobic respiration and produce energy and the chloroplasts were able to independently convert the energy from the Sun to the chemical energy through the process of photosynthesis.
Later, these cells were engulfed by a single cell and these prokaryotes combined to form a eukaryote that was capable of performing all the functions that the independent cells could.
So, the mitochondria and chloroplasts were able to reproduce on their own, had their own ribosomes and had DNA resembling that of bacteria as they were prokaryotic in nature.
However, mitochondria and chloroplasts could not be larger than the prokaryotic cells to support the endosymbiotic theory.
This is because in order to establish a relationship between the bacteria and the mitochondria and chloroplasts, and for these organelles to have developed from bacteria as their ancestors, they must have sizes comparable to bacteria and other prokaryotes.
At the same time, size in itself is not enough evidence to support origin of these organelles from the bacteria.
The symptom that the client is experiencing is consistent with the deficiency in the Vitamin A which is a dietary element. The vitamin A is responsible for causing dryness to the eyes if a person is lacking this type of dietary element as Vitamin A is the one responsible for providing healthy vision for an individual.
