Question

PLEASE.I really need help with this.

Answer 1

1. The largest animal group are the invertebrates, as they include insects as well, which are the most populous.
2. Animal cells are eukaryotic, multicellular and heterotrophic lacking cell walls.
3. A dichotomus key is used to identify and name organisms.
4. All vertebrates have a backbone or spinal column. Examples of vertebrates are mammals and birds.
5. A sponge is an organism that belongs in the phylum porifera.
6. Humans have bilateral symmetry, meaning there is a vertical axis of symmetry through the center of our bodies.
7. False, a phylum is a larger taxon than a class.
8. Domain is the largest taxon, there are three domains, bacteria, archaea and eukaryota.
9. Animals fall under eukaryota.
10. Reproduction is not a part of homeostasis, because homeostasis is the maintenance of constant body conditions.
11. The animal is likely to belong to the phylum chordates.
12. The concentration of sensory organs at the anterior end of an organism is known as cephalization.
13. Radial symmetry allows organisms to move and obtain food in any direction.
14. Insects are more than 70 percent of all known species on the planet.
15. Cnidarians rely on stinging tentacles to rupture their food.
16. Endothermic organisms must eat more food and produce more ATP to maintain their body temperatures.
17. Learned behaviors are taught by parents. Innate behaviors are instinctual, and they do not need to be taught. Learned experiences are gained by organism by experience.
18. All of the above. Binomial nomenclature uses both Latin and Greek names, to make a two-part name with the first part being the genus name with its first letter capitalized and the second part being the species name.
