Answer:
The Idaho giant salamander is the darkest and most intricately blotched of the giant salamanders.[2] They vary between brown, purple, tan, grey, and a copperish color. Tiger salamanders and Idaho giant salamanders have superficial resemblance pertaining to size and shape, but the costal grooves and foot tubercles are significantly different between the two species. This salamander has a defining thick head and body and a fourth toe on the hind foot with only three segments. Adults are typically 20 cm in length[3] but may vary between 7 and 11.75 inches long, but can be observed around 13 inches.

Answer:
The answer is D.
Explanation:
The given situation in the question where an Adenine nucleotide is swapped for a Thymine nucleotide, which as stated are complimentary of each other just like guanine and cytosine, can cause all three types of mutations, frameshift nonsense, frameshift missense and silent because the situation is not specific to either of them. There is no information whether the change resulted in a change in the amino acid structures or not. In this case the best answer is D.
I hope this answer helps.
Answer:
High Temperature, X-rays, Radiation, Some Chemicals
Explanation:
In general, mutations happen due to some error in the DNA duplication process, however, there are certain factors in the environment that can increase the incidence rate of these genetic errors. Excessive exposure to x-rays, substances present in smoke, ultraviolet light, excessive temperature, nitrous acid and some dyes present in food, for example, can favor the appearance of mutations. In general, we can say that mutations can be caused by high temperature, X-rays, radiation, some chemicals.
