So the unit test is coming up on the 28th. I have no idea what date that is, but it's going to be on all the invertebrates. We've learned all of the invertebrates so far except for which we'll learn next week. So um here's what you need to know for multiple choice. There'll be 24 multiple choice questions and then there's going to This is a little different. Two matching sections. One of the matching sections you will need to match the fila names to common animals in the fil. So for example, if I said jellyfish, you'd match that to Nidaria. If I said clam, you'd match that. The second matching section is going to be matching fila to their characteristics. So if I said soft segmented bodies, you'd match that tool. If I said joint appendages, you'd match that to arthropod. So to do well onction you need to know not only what animals are commonly found in a film for the first matching but for the second matching you need to know what the key characteristics are of that file. Okay. So, if I said muscular foot, what biome would that be? Alaska. Good. Um, next section is a little different from the other test. We haven't had this before. There's going to be two diagrams that you need to label. One of them, it seems only fair, is going to be the grasshopper. It will be some of the most obvious se like parts of the grasshopper that you have to uh label and I will later in this class like point out some of the key ones. The other one last semester was the earthworm. We haven't we didn't look too closely at the parts of the earthworm. So I figured it would be nice to put on the sea star which we are going to look closely at on Monday. Um we're going to look at all the parts of the sea star. So the two diagrams you need to label are the uh grasshopper and the sea star. Also in the multiple choice there's about two or three questions on the squid. So, you should spend some time studying the squid, grasshopper, and sea stars, the parts of their bodies. Okay? I will not ask obscure things. They'll be things that are important for the animal to survive. Okay? Um, the next thing is the short answers. Uh, the short answers will be explained two major trends in animal evolution and give examples. So that was back when Miss Love Nikki when she talked about some of those major trends in animal evolution like segmentation, a movement from no germ layers to two germ layers to three germ layers, specialization of uh tissues and organs. And for each of those whichever you pick to talk about as a trend, you want to give an example. So say you want to talk about symmetry as a trend. You could say sponges have very little symmetry or asymmetrical. Some sponges are symmetrical. Nidarians are have radial symmetry uh and then things like arthropods or adelids have bilateral symmetry. Okay. When you animal evolution. It might be helpful to use invertebrate examples. Question two, describe two ways that a specific invertebrate has adapted to a particular environment. I feel like you had a really similar question on the evolution test. There is a way to get this wrong and that is to not describe an invertebrate animal. You tell me about adaptations of a polar bear. You will not get this right. It must be an invertebrate animal adapted to their environment. Question three, describe one cessile and one motile invertebrate found in British Columbia. So you need to know those two words. What do you think cesile means? All right. So let's start with the easier one. What do you think motile means? What does it sound like? It sounds like mobile. What does mobile mean? Able to move. Yeah. So, a motile invertebrate is an invertebrate that's able to move around. Aile invertebrate is an invertebrate that as an adult stays very still. Can you think of adult invertebrates that stay very still would be a cessile invertebrate. Sponges, corals, anemmones would all be considered cesile interpret. Anyways, because I'm giving you this heads up, I'm expecting an actual description of a specific species that lives in Some of the things you'll need to know in the multiple choice. You will need to know the character of all animals. How do you spot an animal? What key characteristics do all animals share? You will need to know some key characteristics about periphera. The role of periphera in an ecos. You will need to know about the different parts of an animal. An anterior, posterior, ventral, dorsal. You'll need to know the general body plan of nidarian both medusa and nar. You will need to know the parts the internal anatomy of a squid. We have to finish the squid lab and get back to you. You will need to uh know some things about platforms. Really, you just need to know how they fit into the ecosystem. Like what roles do they play? Um, you will need to know some classes of phytola. You will need to know how different mollisks eat. It was in your notes. And you will need to know which organisms have open and closed circulatory systems. You will need to know how einoderms move around. You'll need to know the types of cells that make up sponges. You will need to know what things are. Uh you'll need to know what things are. You will need to know what arthropods have their exoskeleton made out of. You will need to know what kind of animals invertebrate animals have endoskeletons. You will need to know the general body plan of a grasshopper. Notice how that keeps coming up. You will need to know the difference between You need to know what it's called. When an arthropod changes from a larva to an adult, you need you'll need to know how different organisms reproduce, especially and I have a crayfish question on it. I suspect I'm going to switch for another organism question. One of the questions is going to be we're just not um so that's what's on the test.
