Compare the structure of the fetal pig kidneys to the structure of the sheep kidneys.

- Both the sheep and fetal pig kidneys are bean-shaped.

- Both the sheep and fetal pig kidneys are reddish-brown colored.

- Both the sheep and fetal pig kidneys have ducts that drain urine into the ureters as a path for urine to leave the kidney.

- One noticeable difference between the sheep and fetal pig kidneys is that the sheep kidney contains more layers of fatty tissue.

The sheep kidneys are lighter in colour and they are found outside of the renal medulla. If we compare the renal pelvis, when in the sheep it is fattier than in fetal pig. Both fetal pig kidney and sheep kidney they have renal vein and renal artery and a section where for ureter which is being attached.

In sheep kidney, the renal capsule in texture it is thicker. The kidney of fetal pig is deeper in colour lets say it is pale brown .

Urine which is being produced in fetal pig it bypasses urethra with elongated bladder and it extends to umbilical cord.

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
