Answers
Answer:
1. Bryophytes are distinct from other land plants (the “tracheophytes”) because they do not contain xylem, the tissue used by vascular plants to transport water internally. Instead, bryophytes get water and nutrients through their leaves.
2. All animals are eukaryotic, multicellular organisms, and most animals have complex tissue structure with differentiated and specialized tissue. Animals are heterotrophs; they must consume living or dead organisms since they cannot synthesize their own food and can be carnivores, herbivores, omnivores, or parasites.
3. Arthropods Definition. Insects such as ants, dragonflies, and bees. Arachnids such as spiders and scorpions. Myriapods (a term which means “many feet”) such as centipedes and milipedes. Crustaceans such as crabs, lobsters, and shrimp.
4. Flying birds have: lightweight, smooth feathers – this reduces the forces of weight and drag. a beak, instead of heavy, bony jaws and teeth – this reduces the force of weight. an enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust.
5.Mammals have hair or fur; are warm-blooded; most are born alive; the young are fed milk produced by the mother's mammary glands; and they have a more complex brain than other animals.
