Chapter 37, Problem 1RQ
What are some reasons a species may be absent from a habitat or region to which it should adapt well?
Expert Solution & Answer
Summary Introduction
To determine: The reasons for the absence of species from a particular habitat or area to which it should adapt well.
Introduction: The geographical distribution of the species can be explained with the help of fossil records. The fossil record indicates that some animals once flourished in the habitats that they no longer cover.
Explanation of Solution
The following are the reasons for the absence of species from a particular habitat or region:
- Some species become extinct through hunting.
- Some species prevent other species from colonizing in a particular region.
- Some physical barriers to the spread of the species are also one of the reasons.
- Environmental changes in a particular habitat also affect the species.

10. Your instructor will give you 2 amino acids during the activity session (video 2-7.
A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids
using the same colors as in #7. Do not color the bonds in the backbone of each amino acid.
B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could
occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds
in the backbone of each amino acid.
C. Position the two amino acids on the page below in an orientation where the two R groups
could bond together. Once you are satisfied, staple or tape the amino acids in place and label
the bond that you formed between the two R groups.
