A charity group wants to give away insect-resistant corn seeds to farmers in poor countries. One of the main insects that harms corn crops in these countries is the corn rootworm. To decide which type of corn to give away, the charity group tests 4 types of corn to see which one the corn rootworms like least.

Data from Rootworm Test

Corn Sample
Name Plant Height
(in feet) Attacked by
Rootworm? Ear Length
(in inches) Pounds per
acre
A 7 yes 8 650
B 4 no 4 2400
C 6 yes 5 1260
D 5 yes 7 450

Some of the farmers receiving the seeds want to grow the corn with the biggest ears because they think this corn will produce the most food per acre. Other farmers think that the tallest plants will produce the most food per acre.

Based on the group's research, which type of corn resists the corn rootworm best and therefore produces the most corn per acre?
A.
Sample B
B.
Sample A
C.
Sample C
D.
Sample D

Sample B

Explanation:

The rootworms don't attack it

4.) metal

"-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."    

i believe the answer would be b. hope it : )
