Succession‚ the process of a community changing over time‚ can be broken down into sub groups such as ecological‚ primary‚ pond‚ and secondary. Ecological succession being the most basic. In the Succession Lab‚ we observed a community in a ecosystem. As we recorded the data each class‚ we observed that succession takes place with rapid speed for in each observation‚ a new specimen is identified. A niche is how the organisms live‚ what their role in the community is. For example‚ an ecological

SAMPLE DESCRIPTIVE LAB REPORT Examination of Protozoan Cultures to Determine Cellular Structure and Motion Pattern Abstract Protozoans are unicellular eukaryotes with either plant- or animal-like characteristics. Through careful observation‚ we analyzed various protozoan cultures in order to identify characteristics associated with cell structure and movement of these one-celled organisms. We found that Protists exhibit certain characteristics that allow them to be categorized into different groups

IN ANIMALS There are so many types of animals such as unicellular‚ small‚ medium size and very large size animals all show movements either they are aquatic‚ arboreal or terrestrial. MICROSCROPIC ORGANISMS Microscopic animals such as Amoeba‚ Paramecium and euglena show following types of movements. (A) Amoeba: Amoeba is found in water. It shows creeping movements. Locomotory movements of amoeba are brought by the formation of finger like projections called pseudopodia (false feet). Several pseudopodia

Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change

1. You are looking at a Euglena using the x10 objective lens. You rotate the nosepiece around to x40 but the specimen is not visible. Describe what you should do next? Start by using the fine adjustment to attempt to focus on the Euglena. However‚ if it is still not visible‚ return to the x10 objective lens and use the fine adjustment to ensure the Euglena is as sharply focused as possible. Then‚ use the stage control to re-position the slide so the Euglena is directly in the centre of the lens.

Week 9 Introduction * Objective * To gain an understanding of the Fetal Pig Anatomy I. External anatomy * The body of fetal pigs is divided by three main parts‚ such as the head‚ neck‚ and trunk. They have also the tails which is located in the posterior end of the trunk. The trunk can be separated two divisions. First one is the anterior

Why do some researchers believe that the Kingdom Protista should be split into more than one kingdom? In the early days of biology‚ all organisms were classified as either plants or animals. Single-celled eukaryotic organisms such as algae and Paramecium were assigned to one of the kingdoms according to whether they are photosynthetic or not. Fungi and prokaryotes were grouped with plants‚ because fungi are sedentary and prokaryotes have cell walls. A five-kingdom scheme was devised because some

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
