Question 10 of 31

Certain drugs can be used in plant breeding to make polyploid plants. These drugs

Select one of the following:

change the number of chromosomes found in cells.

Explanation

Question 12 of 31

Which statement below might be used by someone who is arguing against the use of GM crops?

Select one of the following:

GM crops reduce the amount of land and energy that need to be devoted to agriculture because they have high yields.
GM crops need more insecticide to be used than other crops because they grow faster.
The patents for the seeds of GM crops are held by big companies, which may raise prices and force small farmers out of business.
No studies have shown that GM crops are dangerous to human health.
