The large object in the picture above is a single bacteria cell. The many small structures attached to it are viruses called bacteriophages which are attaching to the receptor sites on the bacteria cell. Which of the following is one important
difference between a virus and a bacteria cell?

Answer Options:

a. a virus is much larger in size than a bacterial cell

b. a virus always causes more severe disease than a bacterial cell

c. a virus can never reproduce on its own, but a bacterial cell can

d. a virus does not contain genetic material, but a bacterial cell does

c. a virus can never reproduce on its own, but a bacterial cell can

Explanation:

a. a virus is much larger in size than a bacterial cell - this is false, a virus is much smaller than a bacterial cell

b. a virus always causes more severe disease than a bacterial cell - this is false, both can be deadly pathogens

c. a virus can never reproduce on its own, but a bacterial cell can - this is true. Viruses are not cellular and need a host cell to reproduce, but bacteria do not.

d. a virus does not contain genetic material, but a bacterial cell does - this is false, viruses contain either a DNA or RNA genome

im back lol i heard you where asking for me

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
