Acorn plant has been genetically engineered. it produces pollen that can make its own toxins. these toxins protect the corn plant against pests. what is a likely impact on the environment around the corn plant?
a. bird and butterfly populations around the area may increase.
b. the concentration of pesticides in a nearby lake would increase.
c. newer strains of pesticide-resistant pests may develop.
d. the carbon dioxide level would increase in the area.

The answer is Newer strains of pesticide-resistant pests may develop.

Explanation:

The plants having their DNA modified through genetic engineering are called genetically modified plants. These genetic modification are done to introduce new traits in plants for example, rapid growth, bigger size, drought tolerance, pests resistance etc. However, there are some concerns related to genetic engineering of plants. When a corn plant will be genetically modified to produce certain toxins that can protect it from pests there will be some negative impacts on the environment. The horizontal gene transfer mechanism can gradually increase the adaptation to that toxin and new pesticide-resistant pests will develop.  

a- multicellular

b-eukaryotic

c-no cell wall
