Question

5)
A population of lizards lives in an isolated area where local rocks contain a high concentration of radioactive elements. A study of this population would MOST LIKELY show
A) a lower than average mutation rate.
B) a higher than average mutation rate.
C) a higher survival rate than other lizard populations.
D) an increase in size compared to other lizard populations.

Answer 1

B) higher concentration of mutation because they're dna would mutate and then they would reproduce passing down the mutation in the genes

Answer 2

Answer: B) A higher than average mutation rate.

Explanation:

• A mutation occurs whenever there is a permanent change in the nucleotide sequence of the genome of any given organism.

• There are several intrinsic and external factors that can cause mutations, one of them being exposure to radiations.

• A radioactive element undergoes radioactive decay and in this process emits radiations that can cause mutations.

• Therefore, the lizards living in the area where there is a high concentration of radioactive material in the rocks will have a higher rate of mutations.
