In a fox population, the allele frequency of a gene for red fur changes from 20 percent to 30 percent.What can be concluded abou
Leni [432]

Answer:

The correct answer would be B. the population is evolving.

It can be explained with the help of natural selection. It is a natural phenomenon by which organisms which are better adapted to the changing environment have better chances to survive and reproduce.

It leads to a change in the allele frequency of that trait in a population.

For example, in the given population, the allele frequency of red fur increases from 20 to 30 percent. That means the population is evolving to adapt to the changing environment.

Roles of bones in bony fish include which of the following?
Rina8888 [55]

Answer:

D All of the above

Explanation:

Like our bones, bones in fish can provide general protection and support to their body.

(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)

The bone is also where the muscles will attach to, which allows for movement.

(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)

Bones can also protect the fish's brain.

(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)
