Its cells are not thought to contain mitochondria but do contain genes that are similar to the genes of muscle proteins. state and explain the domain into which these organisms should be classified.

In the human body, for example, most cells contain mitochondria because they allow for the synthesis of ATP (energy) fueled by the breaking down of sugars (glucose).

Some cells, such as red blood cells, contain zero mitochondria because it is not necessarily beneficial or efficient for them to have any.

In contrast, muscle cells contain more mitochondria than other body cells because more energy is needed for muscles to function, especially during vigorous aerobic and anaerobic activities.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
