BIO 150 Mini Quiz || PASSED!!
An organism's fitness is correct answers relative: it depends on the context/environment the
organism is in
Considering Darwin's observations and inferences, which statement below explains why the
following statement is false? :"Selective pressures cause organisms to better deal with their
environment". correct answers Selection acts on existing variation, it does not cause
individual organisms to change
What is incorrect about this statement: "Evolution and natural selection are the same thing"?
correct answers Natural selection is a process that explains evolutionary patterns.
Mutation is a random process. correct answers agree
Natural Selection is a Random process correct answers disagree
Which of the following is not one of Darwin's postulates about the process of natural
selection? (note: wording does not have to exactly match lecture slides, just the "gist").
correct answers
Which one of the following statements is accurate? correct answers Natural selection works
on variation already present in a population.
Some head lice are now resistant to all commonly used pesticide shampoos used to kill them.
Which is the better explanation for this observation? correct answers Some lice carried genes
for resistance to the pesticide before contact with the shampoos and their numbers increased
after lice shampoos became common.
Which statement describes the swallow (it's a type of bird) with the greatest evolutionary
fitness? correct answers A swallow that lives to be 2 years old and has four offspring, all of
which survive to reproduce themselves
Only the strongest and healthiest individuals in a population will survive to reproduce correct
answers disagree
A chef sprays antimicrobial cleaner on her counter top. At the first, the bacteria population
declines significantly. However, even though she continues to spray in following weeks, the
number of bacteria begins to increase again. Why did this happen? correct answers Some
bacteria had traits that allowed them to survive the initial antimicrobial application. They
produced offspring also carrying those traits.
evolution correct answers change in the genetic composition of a population from one
generation to the next (modification)
pattern of evolution correct answers observed evolutionary change
process of evolution correct answers mechanisms that produce observed patterns of change
