Question

Genetically engineered crops have been created which are more resistant to insect infestations than ordinary crops. Which of the following is a likely impact of the introduction of these crops? A. Crop yields will decrease. B. Insect populations will increase. C. More sources of water will be available. D. Fewer pesticides will enter the environment. 2. Cloning of organisms would allow scientists to complete experiments without having to account for genetic variation. Which of the following is an ethical boundary scientists must take into account in these experiments? A. Whether human cloning is acceptable in any form. B. How cloned animals are affected by their environments. C. Whether cloned plants have the same needs as other plants. D. How the genetic code of cloned organisms differs from other organisms.

Answer 1

Which of the following is a likely impact of the introduction of these crops?
D. Fewer pesticides will enter the environment - because the crops are genetically modified to prevent insects from consuming them, therefore the need for pesticides will lessen.  

2. Which of the following is an ethical boundary scientists must take into account in these experiments?
D. How the genetic code of cloned organisms differs from other organisms - scientists must ensure that codes of genetically modified organisms are totally different from the original organisms they are cloning.
