Maddie and raul were looking at samples of pond water using the class microscope. they saw some things in the water. they thought the things might be alive, but were not sure. they did a search on-line and found this image. it looked like what they were seeing through the microscope lens. were the students correct? explain. a) yes, it is moving in the water. b) yes, it has cell structure with a membrane and nucleus. c) no. there is no sign that what the students are seeing is living. d) it is hard to say. the students must be able to see if this eats anything. 17 points to the 1st correct person. brainliest to the 1st correct person.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

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
