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.

Genetic engineering is preferred because a desired gene to crops may not exist in their species, so conventional agriculture could not be applied. B. Conventional agriculture is preferred because they're natural, and don't have interference in their genome, so they're healthier. C. Genetic engineering is preferred because through it, we can create new species of plants resistant to pests. D. Conventional agriculture is preferred because they produce more crop compared to genetic modifications.arrow_forward

D.Are genetically modified crops typically more expensive?arrow_forwardJenny wanted to know whether the type of fertilizer she used affected how well her tomato plants grew. She wanted to test 3 fertilizers: Fertilizer A, B, and C. Jenny split up her garden into 3 sections and planted the same number of tomato plants in each section. When planted, all of the plants were the same height and all sections of the garden received the same amount of sunlight each day. Jenny used Fertilizer A in section 1 of the garden, Fertilizer B in section 2, and Fertilizer C in section 3 of the garden, ensuring that she used the same amount of fertilizer on each plant in each section of her garden. She watered the plants at the same time of day with the same amount of water for 3 months and then she measured how tall each of the plants in each section were. Which of the following is a confounding variable that could affect the results of the experiment if it is not controlled? Choose all that apply.
