Scientists have discovered a galaxy at a distance of 600 billion kilometers from earth. what is the distance, in au, between the galaxy and earth? 400 au 600 au 4000 au 6000 au

I believe the answer is 4000 AU (NOT 400 AU)

Explanation:

I put 400 AU on my test and got it wrong.

Also try this in calculator:

600,000,000,000 (600 bil) divided by / 150,000,000 (150 mil) = 4000 AU

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
