mRNA will serve as reference book that contains information as the DNA and its sequence is complementary to the DNA template.
The transfer of information in a DNA strand to a new molecule
of messenger RNA is known as transcription. Thus, the process of transcription
is carried out by an enzyme called RNA polymerase and a number of accessory
proteins called transcription factors. However, DNA is copied into mRNA because mRNA will serve as
reference book that contains information as the DNA and its sequence is
complementary to the DNA template.

May not
Explanation:
Adaptation is made possible as a result of an organism being exposed to different environmental conditions. These exposure makes it adopt different techniques for its survival which eventually results in it being adapted to the condition and is then passed on as traits to its offsprings. They are then able to survive when met with such environmental condition.
When an organism is exposed to the same conditions all the time then there is lack of genetic variation and adaptation may not occur.
The right atrium receives blood returning from others parts of the body through the superior vena cava and the inferior vena cava.
Explanation:
The pathway of circulation begins in the right atrium which receives the carbon dioxide-rich deoxygenated blood returning through the systemic circulation.
The deoxygenated blood from regions superior to the heart, i.e., the head, neck, shoulder areas are collected through the superior vena cava and that from the parts inferior or lower to the heart like visceral organs, extremities, trunk, hip etc are brought through the inferior vena cava.
Both these venous systems (superior and inferior) fill the right atrium.
The right atrium then pumps the deoxygenated blood to the right ventricle via the tricuspid valve.
The right atrium is filled with blood during diastole.
