Need help with these for biology

C

D

A

Explanation:

The first answer is C is because viruses cannot replicate by themselves. They must require a host in order to replicate.

The second answer is D because it's what the body does in order to counter a viral infection. A virus doesn't even create antibodies, it attaches itself to cells in order to replicate itself.

The last answer is A since in the last phase of a virus replication (which is lysis), the cell bursts to release the viruses that have been stored inside of it. Since the cell has "exploded" it dies.

3. mechanism for genetic replication

4. the host cell generates antibodies to a viral infestation

5. the cell burst, releasing viruses

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

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
