Put the enzymes in the urea cycle in the correct order, from first to last.

A cycle of biochemical processes, which generates urea from ammonia is known as the urea cycle. This takes place in ureotelic species. The urea cycle transforms the highly toxic ammonia into urea for excretion. The urea cycle occurs mainly in the liver, and to some extent in the kidneys as well.  

The following are the enzymes that take part in the urea cycle are:  

1. Ornithine transcarbamoylase: It transforms carbomyl phosphate to citrulline.  

2. Arginosuccinate synthetase: It transforms citrulline and aspartate into arginosuccinate.  

3. Arginosuccinase / arginosuccinate lyase: It transforms arginosuccinate to fumarate.  

4. Arginase: It transforms arginine to urea.  

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
