You have isolated a small-molecule toxin from a mushroom. When you feed this compound to mice they develop signs of neurological dysfunction consistent with ammonia toxicity. After extensive biochemical characterization, you find that most PII protein is uridylated after treatment with this compound. Which models best explains these observations?

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

hope this !

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

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition
