Technically, there are an infinite number of possible amino acids, though we've found only 20 common ones that many organisms use and at least half a dozen obscure ones that specific organisms use. We focus only on the 20 common ones unless we're in a college level biochemistry course.
The three categories are nonpolar ones, polar ones, and charged ones. The nonpolar ones have non-polar side chains (no oxygens or nitrogens), the polar ones have polar side chains (most contain an OH group but no COOH group), the charged ones are either acidic or basic (has COOH group or a basic nitrogen).
And what are the compounds?
Answer:
See explanation
Explanation:
In this question, we have to remember that in all combustion reactions we will have <u>Oxygen</u> as reactive (
) and the products are <u>Carbon dioxide</u> (
) and <u>Water</u> (
). Additionally, for the states, we will have (l) for the <u>liquid state</u> and (g) for the <u>gas state</u>. So, we can analyze each reaction:
<u>Part A.</u>
The formula for nonane is 
, with this in mind we can write the combustion reaction:
When we balance the reaction we will obtain:
<u>Part B.</u>
The formula for 2-methylbutane is 
, with this in mind we can write the combustion reaction:
When we balance the reaction we will obtain:
<u>Part C.</u>
The formula for 3-ethyltoluene is 
, with this in mind we can write the combustion reaction:
When we balance the reaction we will obtain:

I hope it helps!
Answer:
R selected species are better equipped to survive environmental change because their quick population turnover can quickly adapt.
