Answer: Option C.

High-energy waves like UV light or radiation physically damage the DNA

Explanation:

Mutation is the change or alteration that occur in the DNA sequence or nucleotides sequence of an organism which is caused by mistakes when the organism is copied or environmental factors such as UV light.

Ultraviolet light cause mutations by activating the SOS repair systemof which is a part of i a new DNA polymerase that has no power to edit e but has the ability to move past the thymine dimer and synthesize DNA, This lead to cells able to replicate but with a high frequency of mutations.

The distant ancestors of tigers may have had bodies without stripes. Use the theory of natural selection to explain how tigers m
Degger [83]

The tigers have stripes because it is advantageous for them because they are an ambush predator and need good camouflage. The stripes are excellent camouflage for places that are shady, so the tiger can easily get close to its prey and attack it.

There's a very big possibility that the distant ancestors of the tigers did not had stripes. The reasons for that are different environment, but also that the stripes are actually a very rare type of pattern among the felidae family members.

As the environment started changing, the tigers needed to adapt to it, so they also needed a different camouflage. As some tigers in the population started to develop stripes, they were better hunters, thus were stronger, and seen as suitable mates for the females, as it would provide an offspring with the advantage that the male tiger has. Through this selection in the breeding process of mates that have advantageous camouflage patterns, the stripes were becoming more and more present, to the point where they totally pushed aside and eliminated the previously dominant camouflage pattern.

These question all about ice storms!!!!!!!! answer them in complete sentence
Arisa [49]
The scale used to measure the intensity of ice storms is called the Sperry–Piltz Ice Accumulation Index, <span>based on the expected footprint of an ice storm, the expected ice accumulation as a result of a storm, and the expected damage a storm inflicts on human-built structures.

Meteorologists use Dual Polarization Radar, and the Q2 a mix of sensors and algorithms to predict precipitation.

Yes ice storms can be predicted by weather agencies, and it depends how fast it is detected and how severe it is.
