Carbon dioxide it should be water oxygen
Answer:
The photosynthesis process is interrupted.
Explanation:
Algae produce energy using the photosynthesis process. The reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate is part of this process. Despite this reduction reaction being light-independent (Calvin Cycle), the precursors of this reaction are synthesized in light-dependent steps.
This is the reason why the reduction is blocked when the algae is placed in the dark.
Dalton's atomic theory was based on the law of conservation of mass which states that the matter can neither be created nor be destroyed but it can only transformed into one form or another. In a chemical reaction, total mass of the reactants will be equal to the total mass of the products.
Taking an example,
Mass of 
= 16g
Mass of 
= 
Total mass on reactant side = 
Total mass on reactant side = 80g
Mass of 
= 44g
Mass of 
Total mass on product side = 
Total mass on product side = 80g
It is seen from the above example that the
total mass on reactant side = total mass on product side.
Answer : The correct option is, mixture
Explanation :
Mixture : It is defined as the substance that is made by the combination of two or more different components.
Pure substance : It is defined as a substance that is made by the combination of only one type of atom or only one type of molecule.
Compound : It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.
Element : It is a pure substance which is composed of atoms of similar elements.
According to the definition of mixture, black powder is a mixture because it is made by the combination of red particles that float to the top, black particles that sink to the bottom and a green color liquid.
Hence, the correct option is, mixture
