DNA Replication occurs during the S synthesis phase.
Clown fish do reproduce sexually because there are both female and maleparts involved to it and spern and a egg unite.
If modern animal fossils were ever found in a very ancient geologic period, it would have changed the whole evolutionary theories.
Option B.
<h3><u>Explanation:</u></h3>
Evolution as an event, is very slow and gradually progressive movement. It took millions of years for the unicellular bacteria to evolve and finally make the modern day humans. But the process isn't a haphazard and the evolution processes are well understood by humans. A scientist can clarify how the cell systems became complex to eukaryotic cells, the tissues began to develop, and then the organs and the organ system. The systems like circulatory system, nervous system, muscles, everything slowly grew to evolve animals into a superior one. This is the theory in present days and this is supported by Fossils and different other proofs.
But if one day, a fossil is found which is actually the fossil of a modern animal in very ancient time, its not collaborative with the theories. Modern day animals are born as a result of huge evolutions and presence of them in very ancient times is impossible. So this finding can wipe out present day theories of evolution.
Answer:
"In order to work as an environmental scientist, in entry level job it requires a bachelor degree in environmental science but for the more research type, a person should have a master degree."
Explanation:
In order to work as an environmental scientist, in entry level job it requires a bachelor degree in environmental science but for the more research type, a person should have a master degree. Also with bachelor in biology, engineering, chemistry and physics will be acceptable to begin a career as an environmental scientist. Basically their work is to conduct research, control as well as remove the pollutant source which are affecting the environment as well as the public health. They generally fix the environmental problems.
