Answer:
Answer is A. Red due to ionized hydrogen atoms.
Explanation:
Note that nebula color depends on its chemical composition and its degree of ionization. Because of the prevalence of hydrogen and relative low of ionization energy, its emission appears red.
Answer:
Forms of fossil records can inlude the carcasses of animals and the structure of plants. These records can compare the advancements of creatures over a long period of time.
Explanation:
The further an animal or plant is burried underneath the soil, it is most likely that it lived much longer ago than a layer above it. The theory of evolution suggests that animals are always changing and adapting to their surroundings. For instance, millions of years ago, a dog like mamal existed but over time they grew accustomed to the water, developing fins flippers and eventually developed features similar to what we expect in whales today.
Plants, on the other hand, may have been much larger than the size they are today due to the excess of oxygen present in the atmosphere. Therefore, when they are fossilized scientists can realize that plants have come a long way in the tree of evolution.
The presence of sea-dwelling organism fossils indicate that, at one time, the area was under water.
