Answer:
B
Explanation:
Both of the original DNA strands act as templates during replication. This option is correct.
Answer: The given statement is true.
Explanation: Ionization energy is defined as the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.
General equation of ionization energy is given by:

- If the outermost electron is loosely bound to the nucleus which means that the electron can be easily removed form an atom, it will require less amount of ionization energy.
- And if the outermost electron is tightly bound to the nucleus which means that the electron cannot be removed easily from an atom. And hence, it will require more ionization energy.
Hence, the given statement is true.
Darwin believed in evolution through natural selection; organisms that were the most well adapted to their environment would pass on their genes to their offspring (which the organism would have inherited at conception).
Lamarck on the other hand believed that organisms passed on traits that they had acquired during their lifespan to their offspring.
We know now that Darwin was correct, and that Lamarck was wrong.
Veins carry deoxygenated blood from the body to the heart so it can be sent to the lungs, pulmonary veins takes oxygenated blood from the lungs to the heart.
