For Anyone that put A, its wrong, the correct answer is D
The energy discharged at the time of nuclear fusion or fission, mainly when used to produce electricity is known as nuclear energy. Although nuclear energy has become one of the most potent sources of energy in the present time, it also brings some harmful effects along with it, mainly by affecting the surrounding environment like the water bodies present nearby.
Some of the potential problems for the nearby water sources when using nuclear energy are:
1. It contaminates water with radioactive waste.
2. It creates hazardous conditions for the species living in the water.
3. It adds very hot water to cool water environments.
4. It utilizes a resource, which becomes scarce at the time of drought.
D has a total of four significant figures.
I think it would be adaptation and natural selection because both the terms are when an animal adapts to their environment. I hope this helps!
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
65.39 g Zn ( 1 mol / 65.38 g ) ( </span>6.022 x 10^23 atoms / 1 mol ) = 6.023x10^23 atoms Zn
