The pulmonary vein differ from the other veins in the body because it carries oxygenated blood whereas other veins carried deoxygenated blood
Which means that the pulmonary vein carried out the blood to the entire body as a source for metabolism
hope this helps
Looking at the second cross, a 2:1 phenotypic ratio (instead of the typical 3:1) usually indicate a lethal homozygous genotype. Based on the question, it’s sensible to assume that a snapdragon homozygous for the aureal allele, which should have a even lesser chlorophyll count than the heterozygote, can’t even make it to the birth of the plant, thus the GAGA type never existed in reality. Under this assumption, we can deduce that the 2/3 aurea is of genotype GAG and the 1/3 green offspring of genotype GG. If a punnet square was pulled including the lethal genotype, it will be easily seen that the aureal allele is the dominant type. The first cross of genotype GG x GG conform to this conclusion. And the third is therefore a test cross between the homozygous recessive GG and the heterozygous GAG (aurea), with the result abiding our theory. Correct me if I was wrong, the GA allele is termed dominant negative as a single copy of it results in a deficit in chlorophyll amount. But anyway, the explanation above should give you an answer to the relationship between the G and GA allele.
Answer:
The cytoskeleton protein will be synthesized in the organelle called ribosome. Ribosome is a part of a cell which is responsible for the production of all the proteins needed by the cell.
Explanation: Cytoskeleton protein is a type of protein which helps to maintain the structure of the cell. It also helps in the transportation of materials in the cell and movement of the cell.
