- Please Elaborate your answer In the evolutionary development of organisms, what synapomorphic characteristic body plan is first observed or has first appeared with the annelids? And how is this important to the annelids or the other organisms that have it?arrow_forwardHow are the body plans differ between vertebrates and invertebrates and how is this difference in body plans relate to the survival of the animal in their specific environments? And how do the size and shape of the animal relate to their movement and energy requirement?arrow_forwardFigure 28.21 Which of the following statements about the anatomy of a mollusk is false? Mollusks have a radula for grinding food. A digestive gland is connected to the stomach. The tissue beneath the shell is called the mantle. The digestive system includes a gizzard, a stomach, a digestive gland, and the intestine.arrow_forward
- Figure 27.9 Which of the following statements about diploblasts and triploblasts is false? Animals that display radial symmetry are diploblasts. Animals that display bilateral symmetry are triploblasts. The endoderm gives rise to the lining of the digestive tract and the respiratory tract. The mesoderm gives rise to the central nervous system.arrow_forwardFigure 29.22 Which of the following statements about the parts of an amniotic egg are false? The allantois stores nitrogenous waste and facilitates respiration. The chorion facilitates gas exchange. The yolk provides food for the growing embryo. The amniotic cavity is filled with albumen.arrow_forwardWhich of the following is not a feature common to most animals? a. development into a fixed body plan b. asexual reproduction c. specialized tissues d. heterotrophic nutrient sourcingarrow_forward
- Morphological analogs are structures having similar functions but different origins. For example, the wing of an airplane and a wing of a bird are analogous but certainly have different origins. Name and explain the comparisons of THREE ideas that humans have borrowed from plants and animals to use in building structures and making materials.arrow_forwardBilaterally symmetrical animals have________embryonic tissue layers, known as________ ,___________, and________ . Radially symmetricalanimals have_____________ tissue layers; they lack the___________layer.arrow_forwardYou have received a number of embryos of a bilaterian animal from a colleague, who has asked for your help in determining the specific body plan of this animal. Name four specific characteristics that you will be looking for during the early development of these embryos, in order to classify this animal into the correct group in terms of body plan development.arrow_forward
- Most insects have wings. Which is the other animal phylum that contains creatures with analogous organs?arrow_forwardTOPIC: Vertebrate zoology How are anatomical structures modified from their original form?arrow_forwardBirds are unique because they have modified forelimbs which serve as wings and a body covered in feathers. However, just having wings and feathers does not mean that an organism can fly (look at the ostrich and penguin!). Please discuss at least 3 of these additional characteristics/adaptations that are required in order for birds to fly.arrow_forward
