1. Natural selection causes changes in
populations.
individuals.
genotypes.
phenotypes.
2. Which statement is accurate about natural selection?
Natural selection does not change the alleles an organism has.
Natural selection does not impact reproduction rates.
Natural selection cannot inactivate genes.
Natural selection cannot occur through mutations.
3. Which mutation scenario will always lead to natural selection?
a mutation causes a gene to become inactivated
a mutation causes an inactivated gene to be reactivated
a mutation causes a specific advantage within the population
a mutation causes a specific variation within the population
4. Consider the following scenario:
There are variations in the fur color of mice. Some mice have white fur. Some have dark fur. Foxes more easily catch mice with white fur.
What will likely be a consequence of this scenario?
White fur will become predominant.
Brown fur will become predominant.
Mice with brown fur will be less likely to pass on their genetic information.
Mice with white fur will be more likely to survive and reproduce.
5. What evolves during natural selection?
the proportion of different traits in a population
the phenotypes of individual organisms
entire species
inactivated genes
Scratch what I said earlier. Here's the correct answers:
1. Populations
2. Natural selection does not change the alleles an organism has (even though Google says otherwise)
3. A mutation causes a specific advantage within the population
4. Brown fur will become predominate
5. The proportions of different rates in a population
6. Which of the following describes natural selection?
a process by which organisms purposely change their traits to adapt to their environment
a process by which the strongest individuals in a population survive and reproduce, passing on their advantageous traits
a process by which new species are created through genetic mutations
a process by which organisms mate and produce offspring with different traits
There was no number six, do you know the other answers?
My apologies, I missed that error in numbering. Here are the other answers:
1. Phenotypes.
2. Natural selection does not change the alleles an organism has.
3. A mutation causes a specific advantage within the population.
4. Mice with white fur will be more likely to survive and reproduce.
5. The proportion of different traits in a population.
6. (There was no sixth question.)
