But all of the F1 should be tall because the tall plants are dominant originally
F2 will have 3/4 to be tall, assuming this genetic case is determined by only one factor, like Aa
Answer:
A. Destruction of terrestrial biota
Explanation:
all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.
Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.
Answer:
B.
artificial selection
Explanation:
Artificial selection is often utilized in crop and animal farming to obtain favorable traits in organisms. Organisms with desirable traits are selected and crossed with each other. Since the selection is done by humans and not by natural processes, it is called artificial selection.
In the given case, the farmers select corn plants with large ears. The selected plants are crossed with each other so that the next generation has the maximum chances of producing large ears. Hence, artificial selection is used here.
