8. sea gulls prey on snails on the rocky sea coast. the snails vary in color from solid brown to brown and tan striped. the birds suck the soft snail bodies out of the shells and leave the shells behind on the rocks. scientists picked up 500 empty shells and found that 400 of the shells were solid brown and only 100 were striped. over the years, what would you expect to happen to the snail population?

There would be mostly striped snails.

Explanation:

The snails have a fragile body that is protected by their sturdy shell. However, even with the presence of shells snails are often susceptible to attack by predators, which consume their body and leave only the shells behind.

As you can see from the question above, snail shells range in color from solid brown to brown and striped brown. If scientists take 500 empty shells and find that 400 of them are brown and only 100 are striped, it means that the brown shell snail population is shrinking faster than the striped shell snail population.

This means that in 10 years, there would be mostly striped snails.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
