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'.

What are two ways in which the value of soil can be reduced?

Dovator [93]

Fertile soil is valuable because there is a limited supply. Less than one eighth of land on Earth has soil that are well suited for farming.

The thick, fertile soil of the prairies took many thousands of years to develop.

The two ways that the value of soil can be reduced is help use soil correctly, peanuts were once a corp to help soil, and still can be. The soil value recycle rocks and bedrock.

The value of soil is reduced when it loses its fertility and when topsoil is lost due to erosion. Soil can be conserved through contour plowing, conservation plowing and crop rotation. The thick mass of tough roots at the surface of the soil.

Cells can conduct many task, including which of the following

julia-pushkina [17]

Answer option:

1. duplicate themselves

2. convert energy

3. selectively exchange materials

4. all of the above

Answer:

4. all of the above

Explanation:

Cells carry out many functions. They are able to replicate their DNA and divide into two identical daughter cells in order to proliferate.

They can convert glucose into cellular energy (ATP) through respiration in the mitochondria

They can exchange materials with the outside environment via the selectively permeable cell membrane, endocytosis and exocytosis and active transport via membrane proteins.

Therefore, all of the above is correct.
