(A) The percentage of corn grown that was genetically engineered increased and the use of insecticides decreased.
(B) The percentage of corn grown that was genetically engineered increased and the use of insecticides increased.
(C) The percentage of corn grown that was genetically engineered decreased and the use of insecticides decreased.

▶️Answer/Explanation
Ans : A
Question
What is a description of genetic engineering?
A cross breeding individuals with different important characteristics
B cross breeding individuals with recessive alleles
C inserting a gene from one organism into another
D selecting random mutations to produce new varieties
▶️Answer/Explanation
C
The correct answer is C: inserting a gene from one organism into another.
Genetic engineering involves the manipulation of an organism’s genes by inserting specific genes from another organism to achieve desired traits or characteristics. This process allows scientists to transfer genes that code for particular traits or functions from one organism to another, resulting in the expression of those traits in the recipient organism. This technique has a wide range of applications in fields such as agriculture, medicine, and biotechnology.
