Natural selection is basically nature choosing desired traits in an animal that give it a survival advantage, for example mice with padded feet are not detected by predators as much because they don't make as much noise, they can then keep passing on that gene to different generations

<span>Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

When trying to determine the rate of cellular respiration (an aerobic process), why is oxygen measured and not carbon dioxide
dusya [7]

Since both aerobic and anaerobic processes can result in the production of CO2, we couldn't be certain that cellular respiration was occurring.

Carbon dioxide:

Carbon dioxide is released during cellular respiration as a waste product. Cells that are capable of photosynthesis can utilize this carbon dioxide to create new carbohydrates. Additionally, oxygen gas is necessary to act as an electron acceptor during the process of cellular respiration.

There are two types of cellular respiration: aerobic (occurring when oxygen is present) and anaerobic (in absence of oxygen).

Now, carbon dioxide is emitted as a byproduct in both types of respiration.

Therefore, determining the rate of aerobic cellular respiration by measuring the amount of carbon dioxide emitted is impossible.

Therefore, to obtain the precise rate, we monitor oxygen rather than carbon dioxide.

Therefore, the correct response is that CO2 is created during both aerobic and anaerobic processes; we were unable to confirm if cellular respiration was occurring.

What are the products of aerobic respiration?
bixtya [17]
I am confused as to what your question is specifically asking but the chemical formula for aerobic respiration is:

Oxygen + Glucose --------> Carbon Dioxide + Water
O₂ + C₆H₁₂O₆ --------> CO₂ + H₂O

Hopefully this will aid you in answering your question :)
