Over long periods of time, some species have become extinct, while new species have
descended from earlier species. These changes are known as:

Evolution

Mutation

Natural selection

Adaption

Adaption

The reason why its adaption is because some species become extinct due to not adapting to world changes, while newer species can adapt to world changes.

Hope this helps!

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
