The answer is the axillary artery. In human anatomy, it is a large blood vessel that carries oxygenated blood to the side aspect of the thorax, the axilla (armpit) and the upper limb. Its source is at the side margin of the first rib, before which it is called the subclavian artery. After momentary passing the lower margin of teres major it goes to the brachial artery.

Answer:
The correct answer is
(b)-Chromosomes are made up of protein and nucleic acid.
(c)-Genes are located on chromosomes.
(d)Chromosomes are found in the nucleus.
Explanation:
DNA coils around a protein molecule present inside the nucleus to form a compact structure called chromosomes. These histone proteins have a positive charge and it neutralizes the negative charge of the DNA.
By 1940 it was known by scientists that chromosomes are made up of protein and nucleic acids and chromosome carries the genetic material but at that time it was thought that protein part of the chromosome is the genetic material.
Then Hershey and Chase experiment in 1952 proved that DNA is the genetic material. Mendel first discovered that traits pass from one generation to another as separate factors. Later the word factor converted into gene in 1909 by Wilhelm Johannsen.
So by 1950, it was known that Chromosomes are made up of protein and nucleic acid, Genes are located on chromosomes, and Chromosomes are found in the nucleus.
The correct answer for this question is this one:"Blood flows through capillaries relatively slowly, allowing sufficient time for diffusion or active transport of materials across the capillary walls. In this way, the histological structure of capillaries permits a two-way exchange of substances between blood and interstitial fluid"
Hope this helps answer your question and have a nice day ahead.
