The cardiovascular system branches from the heart two arteries "pulmonary arteries" they are responsible for the diffusion process that happens in the lungs through the blood capillaries which are rounding the alveoli
Answer:
The correct answer would be C) stem.
Modified stems are used as storage organs in potato plant. They are also termed as stem tubers.
They are formed from thickened stolons or rhizomes.
They help in perennation and provide nutrients and energy for regrowth during the following growing season.
The underground tuber survives the winter until spring and help in regeneration of new shoots.
The new shoot uses the food stored in the tuber to grow.
It would be around super giant
There are five mechanisms involve in diversity of organisms:
genetic drift, mutation, natural selection, gene flow and non random mating.
Explanation:
Genetic drift: It is a mechanism in which frequency of the allele changes within a population due to random sampling. It causes decrease in diversity in organism and can result in new species.
Mutation: Mutation in the genes is the most important reason of diversity.the change in DNA causes introduction of new alleles. Harmful mutations do not le species evolve by delimiting them from reaching sexual maturity.
Gene flow: The allele flow happens when a new gene is introduced into a population either by immigration or random mating. when two populations of same species share genes, variation occurs.
Natural selection: The favourable traits for survival are transferred to the offspring. It allows them to adapt better to the environment. It allows maintenance diversity of organism.
Non random mating: The mating between the individual with varied genotype will result in genetic variation.
G hemodialysis is a procedure that patients who have limited or virtually non-existent kidney function undergo to remove both waste products and extra fluid from their bloodstream. blood from an artery of a hemodialysis patient is diverted into an artificial kidney where the blood enters numerous tiny fibers.
