Cultures of a bacterial species were incubated on the shelf of a refrigerator, out on a lab bench top, on the shelf of a 37â°c incubator, and on the shelf of a 50â°c incubator. after incubation, there was no growth at 37â°c and 50â°c, very slight growth out on the bench top, and abundant growth at refrigeration. what term could be used for this species?

The term which can be used for this species is psychrophile. Psychrophilic bacteria are the bacteria which love to grow at low temperature. The optimum they like to grow is 15°c and the highest temperature they grow is 20°c.  

The minimal temperature a psychrophile grows is zero degree Celsius so a psychrophile can grow easily at refrigeration temperature which is 4°c. Phychrotrops are bacteria which can grow at cold temperature but tends to grow well above 15-20°c.

Therefore according to this question, there was no growth at 37°C and 50°C, very slight growth out on the benchtop, and abundant growth at refrigeration which determine that the species is a psychrophile.

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

meiosis is the correct answer
