Do you see a body cavity aside from the intestinal cavity? You may also look at dissected Ascaris and earthworm. Is there a mesentery that suspends the intestine from the body wall in these animals?

- What's different about digestion in sponges compared to digestion in Cnidarians? (Group of answer choices) A. Cnidarians have a complete digestive tract while sponges have an incomplete digestive tract B. sponges have a complete digestive tract while Cnidarians have an incomplete digestive tract C. Cnidarians have a cavity where food is digested, but sponges digest in each individual cell D. Sponges have a cavity where food is digested, but Cnidarians digest in each individual cellarrow_forwardThe rocks and sediments in a gizzard that break apart food mechanically play a role similar to what structures in vertebrates?arrow_forwardYou are investigating a new kind of flatworm and give it food attached to charcoal pieces so that the digestive system can be seen under a microscope. When you look, you can see what you think is a mouth but cannot see an anus. What kind of digestive system would this worm have? -a hematocoel system -a closed digestive system -none of these choices are correct -an incomplete digestive system -radially symmetricalarrow_forward
- Unlike the turbellarians earthworms have a complete digestive system. This means that; The earthworms do not have a typical stomach like other animals do The earthworms have a digestive system with only one opening The earthworms feed similar to fungi; by absorbing materials across the body wall The earthworm digestive system has both a mouth and an anusarrow_forwardUngulates Ungulates, such as deer, reindeer, and elk, are hoofed mammals. These animals have keen hearing, clear vision, supple, well-conditioned muscles, and razor sharp reflexes. The evolution of the four-chambered stomach in ungulates developed as a result of a need to eat quickly in the open and chew later in the safety of cover. This process is called ruminating or "chewing the cud." In other words, ungulates regurgitate and then re- chew their food. Which of the following would be considered a physiological adaptation of ungulates? A) their four-chambered stomach B) their long legs, which help them outrun predators C) their ability to stand perfectly still, which helps them avoid predators D) their ability to hibernate to avoid cold wintersarrow_forwardWhich of the following not only increases surface area for nutrient absorption, but also slows down passage of food through the digestive system to allow for a longer time for absorption? the glomerulus the endostyle the amphibian typhlosole the spiral valve the columella O the pneumatic ductarrow_forward

- If all animals with a circulatory system have a "pump", then what can we say about the genes that code for the development of that structure? OThe genes are analogous. The genes are from aliens!
