What was the environmental factor MAINLY responsible for the changes which were seen in the graph in Figure 3?

my answer

Explanation:

the sun is rusing in noon and at it's very height, carbon-dioxide levels are LOW because the more sunlight plants get, THE MORE PLANTS CONVERT SUNLIGHT WITH CARBON DIOXIDE INTO OXYGEN AND REMOVE CARBON DIOXIDE FROM ATMOSPHERE

it seems that there aren't any factors that can really support it but i would say that the percent seems to lower because of the temp change

Explanation:

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
