Monomers form to combine polymers, in this case a nucleic acid. The monomer of a nucleic acid consists of a nitrogenous base, a phosphate group, and a sugar. The monomers are bound together by phosphodiester bonds. With that information, you should be able to find the answer.

What spectra are you referring to? Mass spectroscopy, NMR, and IR are all referred to as spectra. In addition, you could be talking about fluorescence spectroscopy. How they do it varies, but they are mostly used for identification.

Ok, given the volume and density, you can determine the grams of each compound present. That leaves you with needing to find the moles of acetone in the solution of 85mL, or 0.085L. Now, what quantity can you calculate that would relate grams and moles? Think periodic table. O...

I believe I answered this elsewhere are well, but... Weight and mass are two different things. Mass is a measure of the amount of matter contained in something, weight is a measure of force (F-ma). Doubling the gravity would certainly affect the weight, but do you think it wou...

Mass and weight are two different things. It is true that the object would weigh twice as much, but the mass would remain the same, as it is independent of gravity. Think of mass as a measure of the amount of matter in an object. Weight is a measure of force (F=ma). I agree on...

Say you have two gallons of water in one bucket and one gallon in another. They would weigh different, the volume is different (1 gallon vs 2), and the mass would differ. However, they are the same substance. However, if you boiled the water in these buckets, they would both b...

This question is testing your knowledge of the order of life: Atom Molecule Organelle Cell Tissue Organ Organ System Organism This order starts small and simple and grows to larger and more complex systems. With this in mind, which do you think a plant is?

A trick to solving this type of problem is to reduce all of the ratios to either their simplest form or a percentage. Ex. 3C/6H => 2C/4H => 1C/2H = 50% C 1/2 is the simplest form, and the molecule is 50% Carbon. With this in mind, you should look over your options once m...

Think of the organisms that use diffusion for gas exchange. Most of them have a very high surface area to mass ratio. I'll give you a big hint, there's a relationship between speed of diffusion and the distance over which something is being diffused.

A car starts from rest on a curve with a radius of 140 and accelerates at 1.20 . How many revolutions will the car have gone through when the magnitude of its total acceleration is 3.50 ? If someone could just get me started. Im new to this stuff. I dont understand how if some...
