Ascientist at the polar ice cap was studying an ice sample from hundreds of meters below the surface. while examining the ice, the scientist found some cells from many years ago. using an electron microscope, the scientist identified these cell structures: a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes. what kind of organism did the scientist find?
question 18 options:

animal

bacteria

plant

he did not have enough information.

The correct option is C) Plants

Explanation:

Option A is false because the cell cannot be an animal cell. This is because an animal cell does not possess a cell wall.

Option B is false because the cell cannot be a bacterial cell. This is because a bacterial cell does not have a nucleus. Their genetic material is dispersed inside the cytoplasm.

Option C is correct because all the organelles, a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes, are present inside the plant cells.

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

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
