Answer:
B. oxygen and carbon dioxide.
Explanation:
During cellular respiration, organisms uses oxygen for breakdown of food molecules such glucose and carbondioxide gas is released in the atmosphere. Respiration is a process in which energy is produced in the form of Adenine tri phosphate (ATP) and releases carbondioxide by the chemical combination of glucose and oxygen molecules. The type of respiration in which oxygen is used is known as aerobic respiration.
<span>The two main sources that lead to increased genetic variation are:
</span>1. Gamete mutations
2. Recombination.
Gamete mutations:
Gametic mutations are the mutations that occur in germline cells (sperm and egg). Due to this, the mutations are able to be passed on from one generation to another. One of the most famous gametic mutations<span> is hemophilia.
