Scientists have taken genes from a species of bacteria that is pathogenic to several insects and inserted the genes into potato plants. The bacterial genes cause a cell to produce toxins that kill the insects. As the potato plants grow, every cell of the plant contains the toxin-producing genes. This makes the potato resistant to attack by crop pests.
Which of the following is a limitation of this new technology?
A.
There are no foreseen limitations with inserting bacterial genes into crop plants.
B.
The introduced gene will cause more diversity in the potato's genome, thus causing the potato plant to become extinct.
C.
The genetically altered potato plants will kill off so many insects that companies that manufacture pesticides will soon go out of business.
D.
Over time, insects are likely to develop resistance to the bacterial toxin.

Some species of wasps are social. the queen starts a colony from scratch each spring. she builds a small nest, and lays and raises a group of female workers. the workers enlarge the nest while the queen continues to lay eggs. unfertilized eggs become males that mate with newly hatched females. all of the wasps except the newly fertilized females die by the summer. which best describes this behavior? a)it is beneficial only to the males that do not fertilize eggs. b)it is beneficial only to the female workers that are not fertilized. c)it is beneficial to each one of the individual colony members. d)it is beneficial to the whole species, but not to all of the individual members.
