Explanation:
Oxygen and nutrients from food must be absorbed into the bloodstream to be delivered to cells for respiration. Waste materials such as carbon dioxide must be removed from cells into the bloodstream. Tissues contain capillary networks to allow these exchanges to occur at a cellular level.
Answer: C. Chromosomes
When an egg and sperm cell
unite, fertilization follows. The chromosomes carry the genes that will be
transferred to the offspring. They have threadlike bodies that made up of DNA
and protein that carries hereditary information, which is used to help a cell
grow and reproduce.
Furthermore, humans have 46
chromosomes and 23 in each sex cell and they are found in the nucleus of a
cell.
Here, Genotype of the Purple flower can be determined by "Test Cross", in which Cross will occur between White flower and the given flower.
Case.1) If all the offspring are purple, then the Genotype of that Flower would be: PP
Case. 2) If one of the offspring is White, then the Genotype of that Flower would be: Pp
Hope this helps!
