Answer: Oxygen

Explanation:I hope it helps . i have breifly explained it .

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,  

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.

Differentiated cells in a multicellular organism tend to behave differently from stem cells. The process of differentiation alte
anzhelika [568]

Given what we know, we can confirm that the process of differentiation alters the cells by changing the expression of genes in a cell.

<h3>What is differentiation?</h3>
  • differentiation is when a cell becomes specialized.
  • This is the case with heart or digestive cells.
  • Since all cells carry the same DNA, this does not account for differentiation.
  • Instead, this is achieved by changing the expression of genes in a cell.

Therefore, we can confirm that differentiation is what we refer to as a cell becoming specialized in one way or function, such is the case with heart cells or digestive cells, and since all cells in the body carry the same DNA, this is done by changing the way in which the cells express their genes in the DNA.
