The answer is T, True. Secondary pollutants are pollutants that we do not directly release, but that are created as a side effect of releasing primary pollutants, such as carbon dioxide, sulfur oxides, and particles such as ash and dust. Secondary pollutants include acid rain, ozone, smog, and CFC's (chlorofluorocarbons).
Answer:
A.) Pollen are well preserved in the sediment layers because they are highly resistant to decay.
B.) Other indicators that can be used to determine past climates are through the analysis of the width of tree rings and the coral reefs formed underwater.
C.Glucose
The stomata of plants will close during hot and dry day. This cause a decrease in concentration of carbon dioxide and increase in oxygen concentration in the plant. Photorespiration occur.
As carbon dioxide in photosynthesis is used to produce glucose molecules, the production of glucose molecule will decrease.
