The second farmer used Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn. What is a likely impact on the farmer of growing such a variety of corn? A) The financial costs for the farmer would be lowered since LESS crops would be lost to pests.

B)The financial costs for the farmer would be lowered since MORE crops would be lost to pests.

C) The farmer may be held responsible for increasing chemical pollution.

D) The farmer's expenses for pest control would increase due to an increase in bee population.

A) The financial costs for the farmer would be lowered since LESS crops would be lost to pests.

Explanation:

Planting of variety with a resistance strain to pest is one of the gene modification that occurs in plants, this has greatly help farmers improve on productivity, reducing the amount of money spent on controlling insect pest invasion on their farm.

Because the crop is resistant to pest no extra cost of purchasing chemicals to control pest on the farm and the number of damage to crop will be reduce in turn reducing the amount of plant lost to pest invasion this will lower the financial cost of the farmer and also an increase productivity.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
