Check all the ways listed below that ensure accurate reading of volume from a graduated pipette. tapping the base of the pipette on the table using subtraction to determine the volume dispensed making sure that you read the volume with the liquid inside the pipette at eye level reading only the final volume of liquid after dispensing ensuring that air bubbles are not in the column of liquid inside the pipette

Explanation:

The pipette is a widely used laboratory material, and its main function is to transport precise quantities of liquid material. They are used, for example, in various medical examinations and in the study of molecular biology. There are several types, such as the graduated pipette, the volumetric pipette, the automatic pipette and also the micropipettes (for very small amounts of liquid). Using a pipette requires careful attention not to use wrong volumes of liquid to be used. For this reason, it is correct to say that when handling a pipette we must:

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
