Question

A gene for disease resistance in fir trees is transferred to pine trees using modern DNA technology. How might this be economically helpful to tree farmers?
A) Abnormal pine tree growth would be eliminated.
B) Erosion of topsoil would no longer be a concern.
C) Pine trees would be safe from pine beetle attacks.
D) More pine trees would live to maturity, increasing lumber output.

Answer 1

do you have an idea maybe?

Answer 2

I mean, be reasonable here.

Answer 3

a guess maybe?

Answer 4

For this question, I think the answer would be C. In the question, it is eluding to a gene for disease resistance is transferred to another tree specimen. Therefore, due to GMO or genetically modified organisms can be designed to be disease resistant to insect pests. If the gene is transferred through insertion, translocation etc., then the pine tree would now have the ability to resist an insect pest as well. Letter C is the only answer that implies this fact. Looking forward, even though the plant or tree becomes disease resistant, there can be complications that the pest can become immune or not destroy a balanced predator/prey relationship. Further complications can ensue.
