At 20°C the enzyme that catalyzes the breakdown of polysaccharides functions at 1 reaction every 20 microseconds. If this enzyme catalyzes hydrolysis reactions of a very long polysaccharide molecule for 120 microseconds, into how many segments would this long polysaccharide be cut?

Seven segments

Explanation:

As given in the question -  

After every  twenty microseconds one reaction occurs i.e breakdown of polysaccharides.  

This means that after every  twenty microseconds the polysaccharides is broken down  

The total time for this hydrolysis reaction is   micro seconds

Thus , there will be six phases of division each after every  twenty microseconds

After 1st  twenty microseconds , total segments is equal to two

After 2nd  twenty microseconds , total segments is equal to three

After 3rd  twenty microseconds , total segments is equal to four

After 4th twenty  microseconds , total segments is equal to five

After 5th twenty  microseconds , total segments is equal to six

After 6th twenty microseconds , total segments is equal to seven

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
