When a molecule is made up of one sugar unit, its called a monomer.

<u>Answer:</u>
"The birds have different mating seasons" piece of evidence supports the second student's argument.
<u>Explanation:</u>
The precise timing for bird sets to successfully match varies, and the timing for distinct species develops to give the consequent chicks the best chance of survival. Speciation is the mechanism through which new species are produced. This happens when classes within an individual are separated and diverge reproductively.
Organisms contribute to the same group as per the biological species definition if they can reproduce in order to create healthy, fertile offspring. Group are divided by prezygotic and postzygotic restrictions which prevent mating or producing viable, fertile offspring from each other.
