Exercise 5_Brachiopods Bryozoans-2

Activity 2 (10-15mins) Drawing animal body plans to compare features: Draw a cross-sectional diagram comparing the animals below labelling: tissues derived from the ectoderm, mesoderm, and endoderm, as well as the coelom. (a) Acoelomate (fatworms) ) Eucoelomate (anelids, () Pseudocoelomate (roundworms) Flatworm: Pseudobiceros bedtordi Annelid: Glycera Nematode: Heterodera glycines

able 11.1. Comparison of some representative specimens of cnidarians. Genera Observable stage (medusa, polyp or both) Other distinctive characteristics (solitary or colonial; symmetry; with or wlo deposits) Acropora Aurelia Fungia Hydra Table 11.2. Comparison of the main body regions and appendages of arthropods. Class Body Regions Attached appendages based on body regions Diplopoda Chilopoda Insecta Arachnida XISMATER

Briefly describe:A. cnidarian adaptations that illustrate their major evolutionary advancements past spongesB. the differences between cnidarians and ctenophores and  why ctenophores are evolutionarily more advanced than cnidarians

Question: All members of Chordata have true vertebrae.   True or False?

Page < 3 of 7 4. Using forceps or tweezers, gently pull the 4th or 5th pereiopod to examine its motion. Do so without tearing the appendage off from the body. How would you describe its maneuverability? What are the limitations to motion of these walking legs? Given their small size and limited capacity for muscle attachment, how is it that this animal can use these appendages for motion? 5. Describe the structural differences between the pleopods and the pereiopods up the prawn. What hypothesis can you make regarding the functional use of pleopods by comparison? Pleopods of prawns are far larger in comparison to body size then crayfish (see drawings below). What might this tell you about their use between the two closely related animals? 6. Compare the overall body plan of the prawn to that of an insect like a grasshopper (see drawings below). Provide a complete side-by-side analysis of the two groups that would include body regions, and appendages. Focus your comparison on how the…

Clam I need help with the following questions about Clam When dissecting a clam, what functions of the parts are observed? What is the general feeding strategy of the clam, and how does the digestive system allow it to behave in that way? What is the nature of the circulatory system (open or closed) and is the clam acoelomate, pseudocoelomate, or true coelomate? How does the clam reproduce, obtain oxygen, and get rid of waste?

The legend on the bottom left reflects three basic conditions that describe the character that pertains to body covering (or integument). The conditions that pertain to the specific taxa at the top of the tree are shown by the numbers. Dinosauria Trace the integument character along the tree (you may want draw it out on a separate sheet of paper). Once you have done that step, consider the ancestor of all dinsoaurs.

Weekly Activities: Using body diagrams to compare Protostomes, Deuterostomes, and phyla. You can draw these and insert a picture of your drawing in this doc. Comparing Protostomes and Deuterostomes: Biologists traditionally distinguish protostomes from deuterostomes using developmental characteristics such as the embryonic development of the mouth and coelom. Draw a diagram of coelom formation and the blastopore during embryonic development protostome and deuterostome – labelling the differences in each. The differences between the two are highlighted at the start of the chapter, but you might have to look to google to get inspiration for how to represent these developmental differences via diagrams.
