Answer:
''Stem cells makes copies of itself whereas differentiated cells can't.''
Explanation:
stem cells function differently from differentiated cells because the stem cells divide and make copies of itself. It has the potential either to remain a stem cell or become another type of cell such as a muscle cell, a red blood cell, or a brain cell if the body needed while on the other hand, differentiated cells are specialized cells which performs specific functions and unable to divide.
Answer:
protons /H+
thylakoid membrane of the chloroplast
acid.
Explanation:
This is chemiosmosis. And the ultimate aim is to synthesis ATPs. Proton Motive Force generated from the electron transport chain continuously pump protons(H+) from the stroma into the thylakoid membrane of the chloroplast,
The build up of protons/H+ generated electrochemical gradients between this space and the stroma.
Therefore proton/H+ diffused down the gradient into the stroma. The energy generated from the downwards diffusion is used by the ATPase synthase to synthesize ATPs from ADP and inorganic phosphate (Pi), to be used in Calvin Cycle for CHO, productions.
The protons/H+ pumped by PMF and concentrated in the thylakoid memebrane is obtained from the split of Hydrogen atoms to electrons(e-) and H+. since pH is negative Log of [H+], therefore the space will be acidic from large concentration of H+/protons.
Embryonic stem cells have the potential to produce regenerated tissues, such as skin. They could provide means of healing diseases such as type 1 diabetes where a particular cell has been lost or is malfunctioning.
