What four characteristics are shared by both sponges and humans?
Yes, since it has a backbone, it is a vertebrate. All vertebrates are chordates
A biologist discovers a new species of animal. It does not have a notochord, but it does have a backbone. Can she classify it as a chordate? Explain
Temperature goes up, feed back inhibition causes body to sweat, cools you sin as evaporating, body gets cold, stop sweating, starting to shiver generates heat
Explain how feedback inhibition helps you maintain body temperature
Bilateral, imaginary plane divides the body into 2 equal halves, segmentation, and appendages, cephalization-sense organs
Describe the characteristic of bilateral symmetry in animals. How does this body plan help an animal carry out essential functions
Outermost is the ectoderm which makes skin, nerves, and sense organs, Mesoderm, middle, makes muscle, circulatory, reproductive and excretory system, endoderm, innermost, which makes digestive and respiratory system
How is the arrangement of the three germ layers in an embryo related to the organ systems and tissues in an adult vertebrate?
Different phyla share the same pattern of development, but diff body plans, scientists only considered one, then unrelated animals would be grouped together, Echinoderms- Invertebrates, radial symmetry, no segmentation, no cephalization, chordates, vertebrates, bilateral symmetry have segmentation and cephalization, both deutrosomes
Why should scientists consider both the adult body plan of an animal and its pattern of embryological development when classifying an animal? Use an example to support this
Systems allow animals to survive and reprodce and successfully win its environment, fish with simpler brains couldn’t live on land, while mammals with more complex brains cant live in water
Should the development of a more complex body system in vertebrates be considered an improvement over the simpler body systems of invertebrates? explain
