<span>The correct answer should be C. Public land can be protected and unprotected. This means that it even though things belong to the public they can either be protected by for example military and have forbidden access to people, or they can be unprotected and people can freely visit and do what they want as long as it's not destruction of property in any way.</span>
Whales are closely related to hoofed mammals with an even number of toes, such as horse, because they evolved from them. Before whales were what we know them as today, they were relatively similar to horses. They used the water to flee from predators, and they evolved slowly to heighten their swimming ability, eventually becoming modern day whales. Fish have always been aquatic animals that have gills. Whales cannot breathe underwater, so they take in oxygen the same way a horse does. Also, both horses and whales are mammals that give birth to their offspring and are warm-blooded. Fish lay eggs and are cold-blooded.
