Mitochondria. This is where cellular respiration takes place.
In terms of energy converters, efficiency most commonly refers to how much power was lost in the conversion from steam to heat, or from outlet to shone charger. Some systems 'leak' energy, meaning more energy is going out one way than going in the other. The energy source transfers more power than the energy recipient receives. The more efficient the converter, the less power is lost.
There are three types of DNA Mutations: base substitutions, deletions and insertions.
Base Substitutions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease.
Deletions. ...
Insertions.
Answer:
Cell wall
Explanation:
The presence of a cell wall is a feature of some specific cell types. Prokaryotes such as bacteria possess the cell wall made of peptidoglycan. Cell wall makes outer most covering of their cells in these organisms.
Likewise, archaeans are also the prokaryotes that have cell walls to make the outer most covering of their cells. Among several functions, cell walls in these organisms impart them the mechanical strength and prevent the bursting of cells in a hypotonic environment.
Mitochondria are double-membrane organelles present in the cells of eukaryotes only. They are the powerhouse of these cell types and serve as a site of ATP production by the process of cellular respiration.
Mitochondria are semi-autonomous organelles and have a circular DNA. However, they do not have a cell wall around them.
