Nematode identity card. How are nematodes characterized according to examples of representing beings, basic morphology, type of symmetry, germ layers and coelom, digestive system, respiratory system, circulatory system, excretory system, nervous system and types of reproduction?

Name three disadvantages of sexual reproduction (relative to the asexual alternative). Name one advantage. Diagram the life cycles of a typical scyphozoan (e.g. Aurelia), a trematode, and a monogonontan rotifer, then compare and contrast the features of these life cycles. Be sure to emphasize where and how sexual reproduction, asexual reproduction and dispersal take place. Relate where sex and asex occur in the life cycle to the first part of the question.

Explain the interaction of cuticle, body-wall muscles, and pseudocoe-lomic fluid in locomotion of nematodes.

Compare and contrast the body coverings of a free-living turbellarian, a monogenaen fluke, a cestode, and a nematode. Which problems does each solve or create? Be sure to consider locomotion, permeability, ciliation, and habitat, and to think of the entire life cycle.

D. Describe why we consider the Heterophyids the most invasive parasites among the trematodes.

Amphibian identity card. How are amphibians characterized according to examples of representing beings, basic morphology, skin, respiration, circulation, nitrogen waste, thermal control and types of reproduction?

Fill in the blank. What is the correct sequence of stages in the life cycle of the Chinese liver fluke? To answer - write the numbers with a space in between - e.g. 1 2 3 4 5 6 7  1. adult 2. egg 3. metacercariae 4. miracidium 5. cercariae
