During streak plate technique: Why is it necessary to flame the loop in between streaks?A. To grab bacteria from previous streaked area going into new streaked areaB. In order to count colonies from streaked areas based on previous areasC. To reduce number of bacteria from previous streaked area going into new streaked areaD. to kill bacteria and avoid contamination

Option C, To reduce number of bacteria from previous streaked area going into new streaked area

Explanation:

A loop is sterilized by flaming the loop in between streaks. A streak plate method is used to isolate discrete bacterial colonies so that the number of organisms in the inoculums is reduced. During the procedure, microorganism get deposited in the initial region. This would cause growth of culture across the streaked area and hence the loop is sterilized.

In order to sterilize the loop, it is kept between the blue flame of the Bunsen burner after every section so that the number of depositing microorganism reduces.

Hence, option C is correct

the sun d the answer is sun

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
