Herbicides are chemicals that kill plants by interrupting important biological processes. Different herbicides affect different
plant processes. The herbicide atrazine prevents the chemical reactions that use energy from sunlight. A plant is sprayed with atrazine.
Exposure to atrazine causes an immediate decrease in the production of two substances in plant. Select the substance.
A. DNA
B. Carbon dioxide
C. Oxygen
D. Phospholipids
oxygen because that's one of the substance that plants produce.
You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.
Answer 1 will be vestigial and answer 2 will be dolphins evolved from organisms with legs. Vestigial organs are those which are not in use but were once used by our ancestors for example an appendix
