Answer:
Complex organisms evolved from more simple organisms
Explanation:
<em>Fossil records support the fact that complex organisms evolved from more simple organisms.</em>
<u>Fossils are remains of organisms that have been naturally preserved in rock forms. </u>
The study of fossilized remains of organisms has enabled scientists to establish the fact that earlier organisms are simple types and more complex organisms arose from them through a gradual process of change, otherwise known as evolution. Carbon dating of fossils enables scientists to establish the year the organism existed.
Decomposers include earthworms, small soil beetles, fungi, and bacteria. A food web shows how food chains overlap. The same three types of organisms are in food webs: producers, consumers and decomposers. Good food webs should also include the sun as the initial source of energy.
Answer:
Does not take up the stain.
Explanation:
Negative staining refers to the process wherein the unstained specimen is visualized under the darkly stained background.
One of the examples is capsule staining wherein the capsulated cells are stained with India ink or nigrosin dyes. The particles of these dyes stain the background blue-black but cannot enter the capsule.
Hence, the light-colored capsulated cells are visualized in the midst of the blue-black background.
Peristalsis is the movement of particles through the digestive tract
