Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
Hydrogen ions are actively transported out of the mitochondrial matrix.
Hydrogen ion concentration is higher in the intermembrane space than in the mitochondrial matrix.
The right option is; B) multipotent
This kind of stem cell is multipotent stem cells
Multipotent stem cells are unspecialized cells that have the capacity to renew themselves by differentiating into multiple specialised cell types that has specific functions. Almost all adult stem cells are multipotent stem cells. Examples of multipotent stem cells can be found in the bone marrow where they differentiate, and develop to all blood cell types but not other cells.
I believe the correct answer among the choices presented above is option C. In the oxygen revolution, C<span>yanobacteria were the first organisms to produce oxygen in water, which then escaped into the atmosphere. They were said to be the first microbes to produce oxygen.</span>
Answer:
Explanation:
Consider the small sphere radius is x1.
therefore the large sphere radius is 3x1
As we know that volume of sphere=
So ,
Volume of the small sphere
=
also Volume of the large sphere
=
On solving the equation
volume of large sphere=27 * volume of small sphere
Hence
The correct answer is true, there has always been some sort of life on Earth whether it be bacteria,plants,animals etc
