The word that signifies "within the cell" which alludes to the signals moving from one place then onto the next inside the cell is the term "INTRACELLULAR".
Answer:
a. similar environments and specific traits increased their chances of survival
Explanation:
I eliminated b because of the statement "caused exactly the same mutations." Considering that mutations are entirely random, this would be highly unlikely. Choice a. fits better with the concept of convergent evolution and natural selection. If they evolved in different environments, they would have adapted in diff. ways and thus had diff. body structures.

Blood flows through your heart and lungs in four steps: The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve. The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
