1.

Bt maize has been genetically modified to

resist herbicides only
produce a toxin that kills insect pests
make more vitamin A
grow without water
2.

Herbicide-resistant crops such as GM soya allow farmers to

stop using fertiliser
spray herbicide to kill weeds without harming the crop
avoid insects
grow crops in the dark
3.

A concern about herbicide-resistant crops is that

they are poisonous
they cannot be eaten
they grow too slowly
the resistance gene may transfer to wild relatives, producing resistant weeds
4.

A concern about Bt crops is that

they need more pesticide
insect pests may evolve resistance to the toxin
they kill all plants
they do not flower
5.

GM salmon have been modified to

resist herbicides
make insulin
live on land
grow faster by producing growth hormone throughout the year
6.

An advantage of insect-resistant crops is

reduced use of insecticide sprays
increased use of insecticides
lower yield
more weeds
7.

GM crops may reduce biodiversity if

they are grown in glasshouses
they out-compete wild plants or reduce food for wildlife
they produce vitamins
they are sterile
8.

Golden rice was developed to

resist insects
reduce vitamin A deficiency
resist herbicides
grow faster
9.

A social implication of GM crops is

that seeds are free
that no testing is needed
that yields always fall
the cost of seed, which farmers may have to buy each year
10.

The purpose of genetically modifying crops is generally to

reduce yield
improve yield, quality or resistance to pests, disease and herbicides
remove all genes
make plants sterile only
