Well, whales have special physical attributes that help them keep afloat. for example, it has a special liver filled with oil that helps it to swim. it also uses movement and its fins to keep from sinking. we weigh a tad more than a brick and we still float because we have special adaptations that stop us from sinking - we can swim! can a brick swim? does a brick have these special physical attributes? no! we are alive - bricks aren't.
Webbed feet .
They have webbed feet to help them swim.
To determine the total length of 3 courses of brick, each measuring 10 feet long, you simply multiply the number of courses by the length of each course. Therefore, 3 courses x 10 feet = 30 feet. So, 3 courses of brick at 10 feet long equals 30 feet.
This is a question of evolution. The difference is that in the first case, 'has webbed feet because it needs them to swim' speaks to how the web feet may have come to be. The second case, is ablt to swim because it has webbed feet' speaks to current evolutionary capability.
