Answer:
When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell or a brain cell. There are three characteristics of all stem cells.
Explanation:
Answer:
Cell respiration requires oxygen and glucose. Cellular respiration can be described as a process in which organisms convert sugars such as glucose and oxygen into water and carbon dioxide. A huge amount of energy in the form of ATP is generated through this process. This ATP is used by almost every cell of an organism to carry out its normal activities like metabolism, growth etc.
The oxygen used in cellular respiration usually arises from the atmosphere. Glucose comes from the food that an organism eats.
Answer:
The diagram is attached below.
Explanation:
when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.
Both atoms bonded together through ionic bond.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.

Explanation:
Metamorphic rocks underground melt to become magma. When a volcano erupts, magma flows out of it. (When magma is on the earth's surface, it is called lava.) As the lava cools it hardens and becomes igneous rock.
