The answer is D.
When one is exposed to large doses of X-Rays, this can cause cell damages or even cancer.
I found a similar question, so I think this can be taken as our problem because you seem to forgot including the picture. So, for letter a, the answer is: they represent different compounds. As you can notice, the CH₂CH₃ and CH₃ are both on the top side for the left figure, while the CH₃ and CH₃ are on the top side of the right figure. They are cis-trans isomers. The left figure is trans-2-pentene while the left figure is cis-2-pentene.
Water has high specific heat. So its temperature will not easy to change. Then can help cells keep an even temperature despite temperature changes in the environment.
Answer:
According to Boyle's Law, an inverse relationship exists between pressure and volume. Boyle's Law holds true only if the number of molecules (n) and the temperature (T) are both constant.
Answer:
Honestly, I'm not even sure what the incorrect student was trying to do. The correct answer is:
( ) = the number of elements
(1)N2 and (3)H2
I think the student added the N2 and H2 to "balance" the chemical equation when instead they should have tried the balance the equation by making sure the atoms on the reactant side are equal to the atoms on the product side. You do this by multiplying the atoms on the reactant side until they equal the product side (not by adding them, as the student did).
