Cellular respiration occurs in the mitochondria, the double membrane organelle. It occurs when the cells need energy, storage molecules like glycogen are rapidly broken down from being a polysaccharide to its monomer units which undergo reactions once transported to the cells requiring energy and broken down to release its energy.

Yes, there is a situation where living cells are not respiring. For example in the microbial cell that lives in anaerobic environments in specific environments will use fermentation instead of respiration to produce ATP. The example of this is the yeast cells in beer mash.

Explanation: Another name for gene frequency is the allele frequency. It is the percentage of any chromosomes in the population that contains that particular gene or allele. It also shows the genetic diversity that can present in a species.

Answer:

Biological evolution

Explanation:

Biological evolution is defined as the formation of complex organisms from single ancestral type over a large time period. Evolution believes that all living organisms descended from a common ancestor but not without modification.

There are several evidence to support the theory of evolution including morphological evidence, paleontological evidence, biochemical evidence, among others.

The similarity in the structure and components of DNA of all living organisms is one of the evidence pointing to the fact that living organisms might truly have been from a common ancestor. In addition, all living organisms tend to use ATP largely as their source of energy, giving further credence to evolution theory.
