The comet is visible above the horizon just after sunset, so the sky is still bright. Does anyone have suggestions on which apperture and speed settings for my camera? I want to catch the comet without having the sky overexposed.
Thanks

Why does the sun go on shining
Why does the sea rush to shore?
Don't they know it's the end of the world?--
When you don't love me anymore.

Why does my heart go on beating?
Why do these eyes of mine cry?
Don't they know it's the end of the world?--
It ended when you said goodbye.

I wake up in the morning and I wonder
Why everything's the same as it was.
And I can't understand, no I can't understand
Why life goes on the way it does.

Why do the birds go on singing?
Why do the stars shine above?
Don't they know it's the end of the world?--
It ended when I lost your love.

Don't they know it's the end of the world?--
It ended when you said goodbye.

I can't even understand the question, let alone answer it..any help?thanks!

You are given four test tubes containing purified biological macromolecules. The test tubes are unlabeled except for a number between 1 and 4. You are told that one test tube contains a protein, one contains a lipid, one contains a carbohydrate, and one contains a nucleic acid. You then perform some tests on the macromolecules and collect the following information:
a. Test tubes #2 and #4 contain nitrogen, but the other tubes do not.
b. The contents of test tube #3 are not soluble in water, but the contents of the other test tubes are soluble in water.
c. The contents of test tube #1 can be broken down into subunits that are all exactly identical to each other.
d. The macromolecule in test tube #2 is found to have a globular shape.
What are the identities of the macromolecules present in the four test tubes? Explain how you arrived at your decision.
