To solve this question, think about which one of these options is a DIRECT effect of sea levels rising.
Choice A: If sea levels rise, they would start to cover up land that's at sea level, areas like beaches or coastal cities for example.
Choice B: Fossil fuels cause global warming. This is about the effects of global warming, not the causes.
Choice C: Not relevant. It doesn't mention alternative energy at all in this.
Choice D: Again, effects, not causes (see Choice B explanation).
The correct answer is... CHOICE A
The answer to “most of the energy released by nuclear fission in the form of _____ rays.” is GAMMA RAYS
Answer:
No
Explanation:
The mass fraction is defined as:

where:
- wi: mass fraction of the substance i
- mi: mass of the substance i
- mt: total mass of the system
<u><em>The mass fraction of two substances (A and B), will be the same, ONLY if the mass of the substance A (mA) is the same as the mass of the substance B (mB).</em></u>
An equimolar mixutre of O2 and N2 has the same amount of moles of oxygen and nitrogen, just to give an example let's say that the system has 1 mole of O2 and 1 mole of N2. Then using the molecuar weigth of each of them we can calculate the mass:
mA= 1 mole of O2 * 16 g/1mol = 16 g
mB=1 mole of N2 *28 g/1mol=28 g
As mA≠mB then the mass fractions are not equal, so the answear is NO.
Answer:
I'm pretty sure the answer is C.
