What component of amino acid structure varies among different amino acids? a. the glycerol molecule that forms the backbone of the amino acid b. the location of the carboxyl group c. the long carbon-hydrogen tails of the molecule d. the components of the r group?

The components of the r group of amino acid structure varies among different amino acids

Explanation

As the functional group for amino acids is as:

R-CH-COOH

  I

NH2

only R differs so amino acids also differs. If R is “H” then amino acid is glycine and if R is “CH3” then amino acid is alanine. Hence, R is different for different amino acids. Other components as alpha carbon ( C ), carboxyl group ( COOH ) and amino group ( NH2 ) is fixed for every amino acid.  

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

i won't lie i don't know so go online and ask google thats what i do
