Polar bears live in the north pole, and they rely heavily on the large slabs of ice for many aspects of their lives.
For example, they often hunt for animals in the ocean, and these chunks of ice serve as resting points for the bears when they tire of swimming.
If these ice blocks are melting, the polar bears will have to swim farther distances. Many become tired and don't make it, dying in the process. Therefore, the change in climate negatively affects polar bears.

Explanation:
Mutation rate is largely known as changes that occur in the frequency of a particular gene over an extended period of time
So given that;
the mutation rate of a particular gene = 1 × 10⁻⁶
The expected mutations after 500 million sperm are examined will be:
= (1 × 10⁻⁶)×(500,000,000)
= 500
Thus, The expected mutations = 500
