Which of the following statements correctly identifies a way in which prokaryotic cells are different from eukaryotic cells? Prokaryotic cells have flagella, while eukaryotic cells do not.
Prokaryotic cells have chloroplasts, while eukaryotic cells do not.
Prokaryotic cells only have free-floating DNA, while eukaryotic cells have DNA enclosed in a nucleus.
Prokaryotic cells only have cell membranes, while eukaryotic cells have both cell membranes and cell walls.

Prokaryotic cells only have free-floating DNA, while eukaryotic cells have DNA enclosed in a nucleus.

Explanation:

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
