Answer:
Ozone
Explanation:
In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen.
Answer:
Sunlight stimulates the growth of phytoplanktons which belong to the first trophic level in an aquatic ecosystem pyramid. If these do not exist, aquatic ecosystem would also disappear.
Body fossils include molds and casts. A mold is the imprint left by the shell on the rock that surrounded it. Molds of the underside of shell may be left on the surface of rock that formed when sand or mud filled the inside of the shell.
All amino acids have a center carbon. The center carbon has four different molecules attached to it, these are: AMINO GROUP [NH2], CARBOXYL GROUP [COOH], AN R GROUP [R] AND A HYDROGEN ATOM. There are twenty different amino acids in existence, each amino acid differ from another one based on their R groups. The R group is specific and unique to each amino acid. The center carbon in amino acid structure is also called alpha carbon.
