Cladograms are a way for us to observe and analyze characteristics and evolutionary change between two phylums. Starting out with a character matrix allows us to determine synapomorphies and apomorphies between theses two group‚ allowing us to construct the cladogram (Reece). My cladogram consisted of various phylums from the Animal Kingdom. The outgroup for my cladogram was the Choanoflagellates due to the fact that “they are the closest‚ living‚ unicellular relatives of animals” (Leadbeater).

Animal Phylum Poster/Display Project Each student will select a major group of animals to research and ultimately create a poster or display to help explain the group of animals belonging to each class. Be sure to first read your textbook on the group as well as consult general resources before getting into specific resource materials. Students will be graded primarily on the content of the information as well as the creativity of the poster or display. The entire project is worth 75 points

suspended organs to help them prevent injury‚ enables internal organs to grow and move independently from the outer body wall. Acoelomates‚ though‚ lack a cavity between the digestive tract and the outer body wall. An example of an acoelomate would be a flatworm‚ or planarian‚ While an example of a coelomate would be a rotifer. The differences between protostome and deuterostome development are the characteristics in their cleavage‚ their coelom formation‚ and the fate of their blastopore

ASWAN Dam Project 1843 - A barrage sponsored and completed by the Albanian founder of modern Egypt‚ Mohammed Ali‚ was built. 1882-1890 British engineers helped implement the dam project and began working on the original dam of Aswan. The "low" dam. 1905 – Dam was completed Reconstructed in 1912 and 1933 it was still deemed to be inefficient due to the threats of severe Nile flooding and a second dam was seen as necessary 1948 - Adrien Daninas of Egypt proposed the "high" Aswan dam Financial

eating the ticks. At the same time‚ the carabao gets cleaning of its parasites. Both heron and the carabao benefit from this kind of relationship. 3. a A few examples of parasites are tapeworms‚ fleas‚ and barnacles. Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows‚ pigs‚ and humans. They get food by eating the host’s partly digested food‚ depriving the host of nutrients. Fleas harm their hosts‚ such as dogs‚ by biting their skin

Because they are grouped in the same kingdom‚ the nine animal phyla share the same fundamental characteristics- they are multicellular‚ heterotrophic eukaryotes that obtain nutrients through ingestion‚ they lack cell walls‚ they have nervous tissue and muscle tissue‚ and they reproduce sexually and have a unique embryonic life cycle. However‚ the animal phyla have a great number of differences as well. Some are visible to the naked eye‚ while others are less obvious‚ and still more cannot even be

How Organism Evolved Physiologically Cassi Verkade How Organism Evolved Physiologically Organisms adapt to their environment but what happens when an organism’s surroundings and environment change? Physiological ecology is the study and understanding of that mechanism of living organisms and how living things work. Physiological ecology arises with an understanding of the influence of temperatures. Temperature‚ along with others‚ is one of the most important factors of Physiological ecology
