Answer:-
Which of these groups is more closely related to vertebrates: Mollusks, Echinoderms, Sponges, Cnidarians, or Nematodes
1. Why are both sponges and corals hardened? What benefit does this give the organisms? 2. Compare and contrast the different morphs in Cnidaria in terms of movement, shape, complexity, etc. 3. Sponges and cnidarians have no lungs or gills. How do they exchange gases with the environment? Are humans better off having lungs? Why/why not?
Question 45 1.3 Rather than mesoderm, sponges have and Cnidarians have mesohyl, mesoglea O a second ectoderm layer, nematocysts O amoebocytes, medusae O spicules, a gastrovascular cavity 1.34 pt Question 46
Question 1 1 pts Compared with sponges, cnidarians have a wider array of cell types, permitting more sophisticated tissue functions. These functions include: Select all that apply. secretion of digestive enzymes. epithelial muscle contraction/movement. the ability to perform coordinated filter feeding. the ability to sense the environment via a network of nerve cells.

29.3 Cnidarians Pre-Lab Which specialized cells give cnidarians their name, and what is their function? Cnidarians (phylum Cnidaria) are tubular or bell-shaped animals that live in shallow coastal waters, exce the oceanic jellyfishes. Two basic body forms are seen among cnidarians. The mouth of a polyp is ac upward, while the mouth of a jellyfish, or medusa, is directed dow usa, is directed downward. At one time, both body forms may have been a part of the life cycle of...

For each of the structures below, define the term AND state the group of animals where you would find the structure. radula: spicule: nematocyst: scolex: complete digestive tract: HOX genes: proglottid: hermaphrodite: mantle: corona: 15. We have discussed several animals/groups of animals that are important from a medical standpoint. List and describe some of these medically-important invertebrates. (this includes animals from at least 3 phyla discussed so...
what health monitoring in research is good in animals and why?
1/ a/ Describe the characteristics of true multicellularity in animals. Your answer should include: collagen (what is it, what does it do, etc.), gap junctions vs tight junctions, cell differentiation, totipotency and more. b/ To what extent are the characteristics of multicellularity given in part a shown by Volvox, sponges and cnidarians?
1. Since sponges have a sessile lifestyle, how are they able to protect themselves from predators? What type of spicules do the sponges you use for cleaning posses? 2. IN cnidarians that possess both polyp and medusa forms, why is it advantageous for the reproductive stage to be the medusa form? 3. Explain how the lifestyle of the box jellyfish differs from that of the true jellyfish.
