Plants on land or algae in the water and even some bacteria.
An autotroph or producer is a life form that produces complex natural mixes from basic substances present in its environment, for the most part utilizing vitality from light or inorganic compound responses. They are the makers in a natural way of life, for example, Plants on land or algae in the water and even some bacteria.
Answer:
(E) present the two sides of the debate concerning the development of the vertebrate skeleton
Explanation:
In the paragraph, the author talks about two sides of view in the subject of vertebrates evolution. On one hand, he/she says that the first idea of vertebrates development is that the skeleton evolved as a defensive character and that many researchers rely on soft-bodied vertebrates to conclude it. On the other hand, he/she says that other researchers postulate that some vertebrate features (as paired eyes and adaptation in some muscles) could not have evolved if the first vertebrates were not depredators.
radiometric dating of rocks
fossil evidence
comparative anatomy
molecular clocks
gradual processes of rock formation
Answer;
Explanation;
Radiometric dating confirms that Earth is ancient and explains how extremely slow processes can result in major changes to Earth’s surface. Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place.
-The ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.
