How is the matter different before and after photosynthesis?

Carbon dioxide and water are combined to give glucose in the presence of sunlight and oxygen is given off.

Explanation:

In science, matter is neither created nor destroyed but is changed from one form to another.

Photosynthesis has to do with the combination of water and carbon dioxide in the presence of sunlight to form glucose in the light phase of photosynthesis. The glucose undergoes further reactions in the dark phase of photosynthesis to form complex carbohydrates.

The major changes in matter during photosynthesis are; water and carbon dioxide combine to form glucose and secondarily, complex carbohydrates. Oxygen is given out in the process.

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
