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.
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.)
Answer: True
Explanation: It is not a single organism, there is a photosynthetic and symbiotic relationship between the algae and the fungus.
I believe it is A because Living things respond to changes, each and every living organism is made up of cell and adapting to changes is same as responding to changes.So, only one left is A.
