Figure 15.3 Which of the following statements is false? a. Eumetazoa have specialized tissues and Parazoa do not. b. Both acoelomates and pseudocoelomates have a body cavity. c. Chordates are more closely related to echinoderms than to rotifers according to the figure. d. Some animals have radial symmetry, and some animals have bilateral symmetry.
Propliopithecids vs. Parapithecids. Adapids and Omomyids. Dryopithecus and Oreopithecus. With the exception of Gigantopithecus, many students struggle to differentiate between the various fossil primates. So, let's write about them, have a little fun, and help embed them in our brains. Create an original comic or storyboard that illustrates one of the fossil primates. Unlike the Primate Profiles, this is NOT meant to be a research project! This is meant to be a study tool for you. You should build comics primarily, if not exclusively.
Cephalopods a small group of highly advanced and organized, exclusively marine animals. The octopus, squid, cuttlefish, and chambered nautilus are familiar representatives. The extinct forms outnumber the living, the class having attained great diversity in late Paleozoic and Mesozoic times. The extinct cephalopods are the ammonites, belemnites, and nautiloids, except for five living species of Nautilus. Questions to answer: What effect does the food industry have on Cuttlefish? What impact does global warming have on the Cuttlefish?
The protostome developmental sequence arose just once in evolutionary history, resulting in two main subgroups–Lophotrochozoa and Ecdysozoa. What does this finding suggest? Group of answer choices The lophotrochozoans are monophyletic. The protostomes are a paraphyletic group. Division of these two groups occurred after the protostome developmental sequence appeared. These two subgroups have a common ancestor that was a deuterostome.
Which of these does not pertain to a protostome?a. spiral cleavageb. blastopore is associated with the anusc. coelom, splitting of mesodermd. annelids, arthropods, and molluscse. mouth is associated with first opening

You are trying to identify a living organism which you are observing closely. Which one of the following would convince you that the organism is acoelomate? It responds to food by moving toward it. It is triploblastic. It has bilateral symmetry. It possesses sensory structures at its anterior end. Muscular activity of its digestive system distorts the body wall. The flatworms have a true coelom a pseudocoelom radial symmetry tissues derived from the three basic germ layers (i.e. they are triploblastic) need help with both questions for my HW please thank you!
TRUE OR FALSE 1. The fossil record provides a sweeping overview of the history of life over geologic record 2. A change in the regulation of a developmental gene may have fewer harmful side effects than a change to the sequence of the gene. 3. Synapsids possess an opening known as the occipital fenestra behind the eye socket 4. In some very late cynodont the articular and quadrate bones migrated into the ear region, where they functioned in transmitting sound 5. Fossils contain isotopes of molecules that accumulated in the organisms when they were alive.
