(05.05 MC) Primary production is limited in much of the open ocean by low levels of iron, which is a necessary phytoplankton nutrient. It has been suggested by some that pumps could be placed in these areas that would move iron-rich sediments from the deep into the well-lit euphotic zone, thus stimulating phytoplankton blooms. What problem (human impact) do you think scientists would be trying to address with this biotechnological approach? (3 points)

Reduction of the human impact on marine species diversity

Reduction of bycatch

Reduction of the greenhouse gas carbon dioxide in the atmosphere

Reduction in iron pollution in oceanic sediments

Suggest why placing wheels under a heavy box reduces the neccessary force required to push it along at a constant speed.

Which of the following is the best definition of aerobic respiration? o a. the cellular process that releases energy by breaking down glucose o b. physical activity that involves the repeated motion of large muscle groups o c. physical activity that increases heart rate and breathing rate o d. the cellular process that converts solar energy to chemical energy

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
