AndrewGuerrero BIO 125 Lab Due November 14‚ 2012 Practical Exam 1. a. The symbionts (Paramecium) of the termite belong to the kingdom Protista b. Paramecium living in the intestines of termites breaks down the cellulose walls of wood fibers releasing proteins that are absorbed by the termites’ digestive system. Paramecium benefit by having an environment to thrive and they ingest the wood fibers for their own nutrition as well. 2. c. An important ecological effect

BI108 Animal Biology Lab Report Practical 6: Osmoregulation and Excretion of Vertebrates and Invertebrates Title: Osmoregulation and Excretion of Vertebrates and Invertebrates Abstract: In every aspect of an environment‚ there is a variance in the concentration of fluids present in the environment and the bodies of organisms. Osmoregulation is the regulation of water and ion concentrations in the body. Keeping this regulation precise is critical in maintaining life in a cell

Organ Systems Project (Digestive‚ Excretory‚ Circulatory‚ Reproductive‚ Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus‚ are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free

Compare and contrast Oligochaetes and Caecilians Oligochaetas are earthworms which belongs to phylum Annelida while Caecilians are amphibians that look like earthworm or snakes belonging to phylum Chordata order Apoda and both have similar appearances. Both classes belongs to Eumetazoa having similar characteristics like organ system level of organization‚ increased cephalisation ‚ bilaterally symmetry‚ triploblastic tissue development and coelomate development. The difference is that Oligochaeta

A study of the osmoregulatory capabilities in Nereis virens and Phascolopsis gouldi: osmoregulators vs. osmoconformers Introduction Water is essential for life as we know it on this planet‚ and according to Campbell et al. (1999)‚ water is the major constituent of cells. Reactions vital to life occur under aqueous conditions in the body and cells of all organisms‚ and the concentrations of reactants necessary for these reactions depend upon the amount of water present (Pough et al. 2004)

Most animal phyla originated in a relatively brief span of geological time‚ however the diversity among them is extraordinary. Every organism is very unique a detailed in certain ways‚ comparisons of certain types of organisms can be very difficult. The class in which will be compared is that of the invertebrates. The main difference between coelomate and acoelomate body plans are that coelomates have a true coelom‚ which is a fluid-filled body cavity completely lined by tissue which is derived
