Answer:
Genetic information is bundled into packages of DNA known as chromosomes.
Explanation:
Chromosomes can be described as thread-like structures made up of genes. A genes can be described as a hereditary molecule which is made up of a segment of DNA. Hence, a chromosome contains genetic information packaged into bundles of DNA.
The number of chromosomes vary for each organism. For example, the number of chromosomes in each somatic cell of the human body is 46. These chromosomes occur in the form of homologous pars.
These changes occur due to increased heart rate (measured by taking pulse) without maintaining his normal blood pressure is suggestive of reduced stroke volume. Both drop in blood volume and a weakened heart could cause this, however, the chest pains suggest heart damage.
