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
Answer:
Classifying stars according to their spectrum is a very powerful way to begin to understand how they work. As we said last time, the spectral sequence O, B, A, F, G, K, M is a temperature sequence, with the hottest stars being of type O (surface temperatures 30,000-40,000 K), and the coolest stars being of type M (surface temperatures around 3,000 K). Because hot stars are blue, and cool stars are red, the temperature sequence is also a color sequence. It is sometimes helpful, though, to classify objects according to two different properties. Let's say we try to classify stars according to their apparent brightness, also. We could make a plot with color on one axis, and apparent brightness on the other axis, like this:
Explanation:
Coefficients, you can’t change the subscripts but you can balance the equation by adding coefficients to both sides
Do u have a picture if so post it please
Answer:

Explanation:
Hello there!
In this case, since the reaction for the formation of ammonia is:

We can evidence the 1:2 mole ratio of nitrogen gas to ammonia; therefore, the appropriate stoichiometric setup for the calculation of the moles of the latter turns out to be:

And the result is:
