6. some strains of domestic crops have the ability to produce toxins that deter insects. geneticists can isolate the genes that code for this insect deterring toxin and insert it into the seeds used to plant new crops. what is the advantage of planting these genetically altered crops?
a. the seeds are more durable
b. the new plants have the same leaf size and shape as the strains from which the
dna was taken.
c. the plants are more resistant to insects.
d. the plants evolve into a mutualistic relationship with the insects
e. the plants are more susceptible to insect damage

Which of the following is an example of this type of co-evolution

Chinese privet is a plant that is native to china. over 150 years ago, chinese privet was introduced to the united states as a fast-growing shrub that serves as an excellent privacy hedge. with no natural herbivore, chinese privet quickly established itself and spread in natural areas throughout the southeast and eastern seaboard of the united states. its dominance in these areas has jeopardized the survival of native plant species. chinese privet provides evidence that introducing non-native organisms can cause environmental damage integrated pest management strategies will not decrease chinese privet populations american gardeners can easily control the spread of chinese privet non-native plant species have type i survivorship curves
