Your local senator is calling for an immediate ban on all animal studies proposing that all experiments should be done using cell cultures. Explain to the senator why cell culture may not be adequate on their own and why it may be necessary for researchers to continue using experimental models like small rodents and fruit flies (Drosophila melanogaster) to fully understand human biochemical processes and diseases

b. regulated is the actual answer to your question.

c

explanation:

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
