Q-1: Locomotion on Land

On land most types of animals move from location to place a means of legs. Legs work against the drag of gravity by raising and carrying the heaviness of the body to carry it forward. For rapid locomotion over the ground, a few pairs of longer legs seem better than lots of short legs (Reece, Campbell, 2006). A spider can move across the table much quicker than a millipede can and a mouse can move much quicker than a spider. The less and longer the legs are, however, the better the body must be balanced. In a bug, the body must be mindfully balanced so all its legs support the middle part of the body. A bug moves only three legs at a time because the other three legs are utilized for support. And a bug has its heaviness identical in both the front and behind of the body. Although this is good for balance, this placement is not as good for fast localized shift as in vertebrates.

Many aquatic animals are weightless in water. The buoyancy of the water precisely balances their weight. However, these animals should still use muscular effort to initiate motion. Because water has substantial pull, muscular effort is furthermore required to sustain motion. Some animals have contradictory buoyancy. They sink to the base if they halt swimming. Animals with contradictory buoyancy must consume muscular energy to remain at a granted grade in the water. An animal with positive buoyancy floats to and rests on or near the surface and must expend muscular energy to remain submerged (Reece, Campbell, 2006).
