Drosophila Genetics predictions exercise-L113 (25 pts.) Part I. Meiosis and Punnett Squares Remember, whenever you use Punnett Squares to solve genetics problems, be sure you are completing each of the following steps: 1) Identify the genotypes of the parents. 2) For the specific traits of interest, figure out what kinds of haploid gametes each parent can make. In each gamete, there should be one allele for each trait of interest. If there is more than one trait, make sure all...

Question 1: Homeostasis, Common Ancestry, and
Divergence
a) One problem that all respiring organisms share is the
need for biological structures that allow efficient uptake of
oxygen and removal of carbon dioxide. Two types of structures that
have evolved for carrying out gas exchange are gills and lungs. The
table below lists organisms according to the type of structure they
use for gas exchange.
Describe the general process of gas exchange that occurs
between a gill or lung and the...
