Abacterium called bacillus thuringiensis (b. t.) contains a protein that can kill cotton ballworms and certain other kinds of caterpillars. a different bacterium called agrobacterium tumefaciens has the ability to insert its genetic material into plants. scientists in the late twentieth century took a gene from (b. t.) and inserted it into specimens of agrobacterium tumefaciens. genetic material from the agrobacterium tumefaciens specimens was then inserted into cotton plants. the goal of these tests was to reduce caterpillar infestation in the cotton plants.

This is genetic engineering.

I hope this helps!

genetic modification.

Explanation:

c. is the answer

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
