Question
Chapter 38, Problem 6A
Summary Introduction
Introduction:
For the recognition of the pathogens, the plants and the animals have developed certain receptors, which recognize the patterns present on the surface of the pathogens. The recognition of the molecules induces the innate immunity.

Which letter is correct
A. 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.

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 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.arrow_forward

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 resistantarrow_forwardMany concerns have been raised about the safety of GMOs. These are all concerns that have been raised EXCEPT A. Genes that offer herbicide resistance will be passed on to weedy species making "superweeds". b. GM crops will cross with non-GM crops and move the recombinant genes into crops where farmers don't want them. c. Genes added to crop plants can negatively affect the health of people who eat the crops. d. Genetically modified crops increase the use of fossil fuels and therefore increase the production of carbon dioxide.arrow_forwardHow would a scientist introduce a gene for herbicide resistance into a plant?arrow_forward
