Answer 2

Answer:

1. Unlike most birds, their flat breastbones lack the keel that anchors the strong pectoral muscles required for flight. Their puny wings can't possibly lift their heavy bodies off the ground.
2. Herbivores have long and strong legs which help them in finding food. in addition to this they also choose their food very slowly which helps them to break down plants that they consume. Hence they have long and strong legs which enabled them to to find their food and to utilize it properly.
3. The cockroach life cycle is comprised of three developmental phases, the egg, nymph and the adult stage. Most cockroaches are oviparous — their young grow in eggs outside of the mother's body. In these species, the mother roach carries her eggs around in a sac called an ootheca, which is attached to her abdomen.
