The answer to this one is true
Heredity<span>, </span><span>the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring. The concept of heredity encompasses two seemingly paradoxical observations about organisms: the constancy of a </span>species<span> from generation to generation and the </span>variation<span> among individuals within a species. Constancy and variation are actually two sides of the same coin, as becomes clear in the study of </span>genetics<span>. Both aspects of heredity can be explained by </span>genes<span>, the functional units of heritable material that are found within all living </span>cell<span>s. Every member of a species has a set of genes specific to that species. It is this set of genes that provides the constancy of the species. Among individuals within a species, however, variations can occur in the form each </span>genetic<span>s, providing the genetic basis for the fact that no two individuals (except identical twins) have exactly the same traits.</span>
Answer:
In the adult heart, blood in the right chambers of the heart cannot enter the left chambers without passing through the lungs. (Ans. A)
Explanation:
In heart, heart muscle cells is responsible for the circulating the blood throughout the body. The heart contains four chambers, two upper called as atrium and two lower called as ventricle, 1 atrium and 1 ventricle present on both right and left sides of the heart.
Blood which is returning from other parts of the body and is no longer oxygen rich, enters from the top right chamber of the heart. Than this blood is pumped into the right vertical and through the pulmonary artery into the lungs for absorb more oxygen.This oxygen rich blood is then pumped into the top left chamber present in the heart, and then into the lower left chamber before being pumped out into the body from the aorta.
So, the answer is A.
Remove individuals from a population
