Question
i know the answers for each question below is correct. Can you tell me why they are correct and why the others are not?
can you tell me why population is the correct answer over the other ones?
which of the following evolve?
a. kingdoms
b. population
c. phyla
d. individuals
e. genera
ANSWER is d but why over the others?
An insect that exhibits resistance to a pesticide ...
a) developed resistance in response to exposure to the pesticide
b) mutated when exposed to the pesticide
c) inherited genes that made it resistant to the pesticide
d) is less likely to pass on the allete to the next generation
e) none of the above
can you tell my why the others are incorrect and genetic drift is the ansnwer?
When a population goes through a bottleneck,
a. genetic drift is likely to occur.
b. mutation rates increase.
c. extinction rates decrease.
d. natural selection decreases in intensity
e. mutation rates decrease
Explanation / Answer
Please find the answers below:
Answer 1: Kingdom is the largest phylogenetic class, genera are the types of specific organisms existing in a species and individuals undergo mutations but not evolution. Population represetns a set of similar kind of organisms which undergoes evolution)
Answer 2: Development of antibiotic resistant is a non-genetic event and usually does not pass through generations since it arises from random mutations. Hence, non-gametic mutations are mostly associated with antibiotic resistance)
Answer 3: Bottleneck effect arises due to cutting off of a set of populations from the mainland and its rehabilitation at another location, leading to genetic drift. The mutation does not help in this evolutionary force and hence does not help in genetic drift.
