Answer:
The correct answer is - stem cells.
Explanation:
Stem cells can give rise to all tissues and organs in the body. These cells can differentiate into any form of cells, which allows them to repair tissues that have been damaged by various physiological or natural ways
There are two types of stem cells: Adult Stem Cells and Embryonic stem cells.
Cells that are present in the bone marrow or umbilical cord of a newborn baby and can be divided as Hematopoietic, a cell that can form blood cells and the immune system, and mesenchymal that form the body's cartilage, bones, muscles and other.
Embryonic stem cells are found on at blastocyst stage of embryo. These cells can transform into any type of tissue in the human body, which increases their treatment potential.
Answer:
Before they replicate the two DNA strands need to separate from each other.
Explanation:
You would use the graduated cylinder to find the volume of the object (usually in mL).
So, the answer is Option C: volume.
Answer: B, C and D
Explanation:
Option A is wrong because protons are not pumped into the matrix of the mitochondria, but rather protons are pumped from the mitochondrial matrix to the inner membrane space.
Option B is correct. The NADH dehydrogenase, cytochrome b-c1, and cytochrome oxidase complexes are all protons pumps and pump protons across the membrane.
Option C. Is correct. The pH inside the mitochondrial matrix is higher than in the innner membrane space.
Option D is correct. The mitochondria use the proton gradient to synthesize ATP by the enzyme ATP synthase.
