These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the farmer relies on
manually removing the weeds, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are
herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the weeds but does not harm the crop. For many years
this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been
sprayed with herbicide.
Which of the following is likely the reason the weed has remained?
A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
O The weed needed to be resistant in order to survive, so it became resistant

Which of the following is likely to happen if that weed stays in place?
The weed will survive long enough to reproduce.
In time, the herbicide will no longer be effective on that field.
The trait will spread to nearby weeds.
