Nitrogen Bases of DNA – These are rather complex single or double ring structures containing nitrogen and are attached to the carbon of the sugar. Nitrogen bases are of two types based on the number of rings. Purines Purines are double ringed nitrogenous bases which are linked to sugar by using nitrogen present at 9' …

## Write the expression in terms of sine only help?

sin(x) + cos(x) = sin(x) + sqrt(1 – sin^2(x)) Well the first term is already sin(x), so we just need to express cos(x) in terms of sin(x). You know the identity sin^2(x) + cos^2(x) = 1, right? Well solving this for cos(x) and substituting it into the original expression gives sin(x) + ±√[1 – sin^2(x)], …

## How many strands of icicle lights can I plug together without blowing a fuse? I only need 4, is that to many?

You should be fine, we hung ours up this weekend and did 4 strands together & haven't had any problems. If you use the new LED lites you'll be OK. There usually is a warning on the lights "do not string more than 3 sets together" or similar. I have done 4 and nothing has …

## Converting g/cm3 to lb/ft3?

So I have surfed and surfed the net and read and read through my chem and physics books and there is no clear conversion factor for g/cm3 > lb/ft3. Everytime I try to do the conversion I get different numbers. Its driving me CRAZY!!!! If someone could clearly write out the conversion factor for me …

## What characteristics do all eukaryotic cells have in common?

All Eukaryotic Cells Have nucleus, endomembrane system …. etc. read your textbook, it's not a difficult question at all They all hold prisoners? I don't know, I'm just a democrat. Eukaryotic cellscellscells are a sort of telephone greater suitable puzzling than their opposite numbers, prokaryotes. Prokaryotes comprise the simplistic bacteria and archaea, on the comparable …

## How much does 8 quarts of water weigh?

There are 4 quarts to a gallon, so that's two gallons of water. One gallon of water weighs about 8 pounds, so two gallons is about 16 pounds. 16.7 lbs, approx We would also need to know the temperature of the water and amospheric pressure. Think of it this way: Imagine 8 quarts of ice …

## Where are the ionization nebulae predominantly located in the galaxy M51?

A)distributed evenly throughout the galaxy B)within or on the edges of the spiral arms of the galaxy C)in the central bulge of the galaxy D)in the wide spaces between the spiral arms I know its not D, I kind of think its C but I am not sure Why are the ionization nebulae so bright? …

## What is the number of moles in 9.63 L of H2S gas at STP?

1 mole of any gas occupies 22.4 L at STP. Therefore, (9.63 L) / (22.4 L/mole) = 0.43 moles of H2S. Safely & Permanently Remove Moles, Warts and Skin Blemishes

## What molecules make up the sides(backbone)of the dna ladder?

sugar and phosphate its as simple as that! 1. phosphate and sugar adenine bonds with thymine, with the exception of copying it onto mRNA. cytosine bonds with guanine. Adenine – Thymine Guanine – Cytosin think of it as AT & GC lol Deoxyribose (a sugar) and phosphate form the backbone. Adenine bonds with Thymine (and …
