BIO 150 Mini Quiz Question and answers
rated A+ (6 pgs)
Mutations are changes in the sequences of - correct answer ✔
An organism's fitness is - correct answer ✔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 answer ✔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 answer ✔Natural selection is a process that explains
evolutionary patterns.
Mutation is a random process. - correct answer ✔agree
Natural Selection is a Random process - correct answer ✔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 answer ✔
Which one of the following statements is accurate? - correct answer
✔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 answer ✔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 answer ✔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 answer ✔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 answer ✔Some bacteria had
traits that allowed them to survive the initial antimicrobial application. They
produced offspring also carrying those traits.
evolution - correct answer ✔change in the genetic composition of a
population from one generation to the next (modification)
pattern of evolution - correct answer ✔observed evolutionary change
process of evolution - correct answer ✔mechanisms that produce observed
patterns of change
natural selection - correct answer ✔process in which organisms with certain
inherited traits are more likely to survive and reproduce than those without the
trait
