Answer:
<u>Uranium</u> is the inner transition metals is critical to the nuclear power industry.
Explanation:
Uranium is a common transition metal found in rocks and is used for nuclear fission reactions. In a nuclear fission reaction, a neutron atom is hit on a uranium atom. As a result, the uranium atoms breaks down releasing huge amounts of energy. Also, more neutrons are released by the breakdown and hence the this neutron hits other uranium atoms and the cycle continues. The most active radioisotope of uranium being used in nuclear fission reactions is U-235.
the basic unit of life is the cell
The answer is A. Excretion I hope this helps
Your answer would be D, because these are all relating to how the actions of the scientists will affect the environment and/or organisms.
