Answer:

The red blood cell shrinks

Explanation:

According to the question, the solution the red blood cell was placed in has a concentrated salt solution, this implies that the solution is hypertonic i.e. high solute concentration in relation to the blood cell, or otherwise the red blood cell's content is hypotonic i.e. low solute concentration in relation to the extracellular solution.

Due to this difference in concentration between the cell and the external solution, an osmotic flow occurs. Osmosis is the movement of water from a region of low solute concentration/high solvent concentration to a region of high solute concentration/low solvent concentration through a semi-permeable membrane, which in this case is the membrane of the red blood cell. This osmotic gradient causes water to flow out of the red blood cell (where the solute concentration is low) to the extracellular solution (where the solute concentration is high).

Hence, the red blood cell loses water and shrinks or reduce in size.

A group of mutations, known as MT-ND1 , have been identified in mitochondrial DNA . These mutations are associated with a number

Doss [256]

<h2>Production of mitochondrion DNA </h2>

Explanation:

The cell is not capable to complete reaction related to ATP production and electron transport.
This is because the electron transport chain and ATP production are combined with the association of protein in the inner membrane of mitochondrion DNA.
Mitochondria are the powerhouses of the cell. In all eukaryotes that don't rely upon photosynthesis, the mitochondria are the primary wellspring of adenosine triphosphate (ATP), the vitality rich intensify that drives central cell capacities.
These capacities incorporate power age (for instance, in muscle compression and cell division), the biosynthesis, collapsing and debasement of proteins, and the generation and control of membrane possibilities.

Identify mitochondria in an illustration of a cell.

Svetach [21]

<em>Answer: Mitochondria are found in all body cells, with the exception of a few. There are usually multiple mitochondria found in one cell, depending upon the function of that type of cell. Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.</em>
