Which of the following is not one of the body's chemical buffering systems? a) hydrochloride b) protein c) bicarbonate d) phosphate

A

Explanation:

Buffers are molecules that  resist fluctuations in pH by donating or accepting electrons  with the introduction of more  acids or bases to a solution.

Their  general function in all living organisms  is to maintain relatively constant  blood plasma pH  for effective biochemical reactions.

In living cells  examples  are;

Carbonic acid bicarbonate;  buffer system to neutralise elevated hydrogen ion from high blood carbon dioxide

Protein buffer system;  mopping of excess hydrogen ions by haemoglobin

Phosphate buffer system ;, for neutralisation of excess  hydrogen ions   by releases of hydrogen phosphate  ions  

Therefore A is odd.

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
