Questions and Answers 100% Pass
Describe an effective experimental design to determine whether an environmental
variable imposes selection on a trait. - ✔✔-need multiple generations
-need a control group
-need different levels of oxygen
-need a small organism that reproduces quickly
-need a confined environment
How does natural selection cause dramatic changes in phenotypes? - ✔✔Different levels
of oxygen can change body size, certain phenotype survives, reproduces over
generations to become popular in populations. Higher oxygen levels means animals can
grow larger and still maintain the supply of oxygen to their muscles.
