    Just like pores on human skin which absorb elements of the world around us, the holes all over the sponge’s body as essentially pores as well. The function of the holes all over the sponge’s body is to allow water to be absorbed into the sponge’s body. Through the absorption of water, the sponge also absorbs food and oxygen to ensure survival. There is no one set type of symmetry for sponges. Therefore, not all sponges have the same type of symmetry. Sponges can range from asymmetrical to…

At some point, members of that group share the same body plan during their development process.

    To start off the exhibit is the Precambrian period. The Precambrian period lasted for 4 billion years. Scientists believe that this period where 90%of earth's history was discovered. Life first started evolving, and progresses and changed the planet. Scientists discovered the truth about organic compounds, the first prokaryotic cells and the first meteorites to hit the earth. Scientists believe that some of these meteorites gave rise to organic compounds, or life's building blocks. The Cambrian…

    Murine Typhus caused by Rickettsiae typhi. This bacterium is spread most commonly by the bite of an arthropod insect such as lice, fleas, mites, and ticks. When an arthropod feeds on a human host or rodent who has the typhus disease, the insect then contracts the bacterium. It then is able to grow and reproduce inside the intestinal cells until it is released in the fecal matter of the arthropod. Even if the insect is killed by the disease before it can feed on another host, the infection is…

    embryos undergo spiral cleavage, which mean micromeres between micromeres. The cells that formed are determinate, which means that the blastomere fate is established during the early stages of development. Animals like Platyhelminthes, Molluscs, and Arthropods are examples of some protostomes. Deuterostome development means that an organism develops anus first near the blastopore…

    Locomotion is the movement of a body from one place to another. There are various ways in which species of organisms in the 9 major phylum classes of the kingdom Animalia adapted unique muscle systems and how they use them. A phylum class includes organisms that are different but share important characteristics that resulted from evolutionary relationships among major groups of animals that allowed organisms to adapt in terms of the way they locomote. The Phylum Porifera is made up of sea…

They are multicellular, heterotrophic, invertebrates with an irregular shape and no distinct pattern of symmetry (Myers, 2001a). Overall, they are the simplest of animals; thus, lacking any true tissue and/or germ layers (Myers, 2001a). Furthermore, they are known to be highly sessile,…

    habitats (Ginsberg and Ewing 1988). One type of trapping methods to use is the dry ice baited tick trap. This method can be accomplished by inserting dry ice into a container that has a slight opening to allow the carbon dioxide gas to exit, and the arthropods will be trapped by a layer of masking tape around the container. Because the ticks and other hemophagic vectors are attracted to the carbon dioxide emitted by humans and animals, thus the dry ice is effective in stimulating their host…
