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.
Because they have to go through the non-polar, hydrophobic tales of the phospholipid bilayer. Polar and non-polar do not like to be together

Explanation:
Carbon dioxide is a type of colorless gas that is present in the atmosphere in a very trace amount. This gas plays an important role in the process of photosynthesis that occurs in green plants. There are many sources that increase the percentage of carbon dioxide in the atmosphere that has an adverse effect on nature and causes global warming. Car, trucks and many other machines are responsible for the production of carbon dioxide gases directly or indirectly.
Sharks, whales, and dolphins share similar features such as body shape and the position of fins. However, sharks have gills for breathing, while whales and dolphins have lungs. Sharks and dolphins are similar in construction because they need their parts to complete many of same functions.
For example:
The dorsal fins that are found in both shark and dolphin are due to convergent evolution and they are actually not from common ancestor.
