<span>Aerobic respiration uses oxygen while anaerobic respiration does not. In aerobic respiration, it occurs in most cells. It releases High amount of energy at 36-38 ATP molecules and it reacts with glucose and oxygen. It produces carbon dioxide, water and ATP. While in Anaerobic respiration, it occurs mostly on prokaryotes. It releases lower energy between 36-2 ATP molecules and it reacts with glucose and electron acceptor which is not an oxygen. It produces carbon dioxide, reduced species and ATP. The site of both respiration is in the cytoplasm and mitochondria. -ahnnahly</span>

MArishka [77]

Answer:

Yes

Explanation:

A high quality DNA sample will have a 260/280 ratio of around 1.8. This value means that the DNA is sufficiently pure and free from other contaminants that could affect downstream experiments and analysis.

The ratio for this sample is 0.489/0.257 = 1.9

This is close to 1.8, and therefore the sample is of sufficient quality ot use downstream.
