Paramecium is a single-celled protist from the Alveolate clade. They live in wet environments like lakes, ponds, streams, rivers, and puddles. The wet environment can even be inside of animal bodies and in moist soil. Paramecium are heterotrophs, meaning they eat other living or non-living things. They eat by trapping food inside of their oral grooves, which are basically mouths. They use cilia on their body to not only move, but also help capture their prey. When the food gets into the oral…

things. All organisms are composed of one or more cells and have an outer layer of a plasma membrane (or cellular membrane), which acts as a barrier that divides the cell from its surrounding environment. The plasma membrane of a cell acts as a physical barrier and regulates the exchange of materials with its surroundings. It is a permeable membrane that surrounds the cytoplasm. The contents held within the plasma membrane are called cytoplasm. In prokaryotes, or single-celled organisms, it is…

Ethologists group all the behaviors into two categories: learned behaviors, are those behavior acquired through experiences, and innate behaviors, do not require any experiences, is part of the genetic endowment. In this Lab, the specific eukaryotic organism Porcellio Scaber is being studied. Porcellio Scaber is an animal, which obviously…

The concept of possibly being able to resurrect long extinct creatures have been around for decades and has now after years of research just received the spark it needed to bring that concept to reality. In early 2003, fossils of a T. Rex were discovered and although this was not very uncommon, the realization of what was within those fossils were the real surprise. Scientist discovered that one of the bones within it was very much intact and interweaved to it was what looked like to be a system…

Scientific experiments and observations have led to many discoveries, which in turn have allowed scientists to develop a better understanding on the way diseases originate in humans. Molecular biology in particular has allowed scientists to discover the way in which domains, found in proteins impact a genome. Domains are autonomous folding units that carry out specific functions and mechanisms in a certain protein. These functions consist of being responsible for interactions in the cell, which…

INTRODUCTION Being able to identify an unknown specimen in microbiology is vital in the laboratory. The goal of this experiment was to isolate bacteria on a nutrient agar (NA) plate to obtain pure colonies of the unknown specimen. This study was done by applying the methods learned in Professor Sprenkles microbiology lab in determining the unknown bacterial growth present with use of pure culture colony morphology, cell morphology and arrangement, and Gram reaction. MATERIALS AND METHODS The…

have 10 or less genes. But organisms such as the meme virus, mega virus and the Pandora virus prove us wrong. In some cases, some of these controversies to the change of biological evolution is in heredity by accident, natural in nature or caused by mutation. Before 2003 there only two kinds of living things on earth which were cellular life and viruses; the cells were considered humans and any other living organisms that could grow. (3:06) then viruses were organisms made out of genetic…

Earth through its birth. If humans were around we each would have witnessed the birth and death of the mountain ranges, and the ice ages that comes and goes like the storms we have today. Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of Earth. During the investigation of Evolution two scientist by the names of Charles Darwin and Alfred Russel Wallace, and their contemporaries were forced…

Physical rather than biological; not derived from living organisms. Biotic - Relating to, or resulting from living things, especially in their ecological relations. Explain each of the following: organisms, populations, communities, ecosystems, and biomes. Organisms - An organism is a living thing. It is easy to recognise a living thing, but not so easy to define it. Animals and plants are…

Inquiry Question: Module #6 Chapter 11 Books cited: Becker’s world of the cell: J. Hardin, G. Bertoni, and L. Kleinsmith: 8th edition; pgs.298-299 & 301-307. Question #2 from D2L: The endosymbiont theory attempts to explain the evolutionary origin of eukaryotes. Describe this theory in a paragraph. Be sure to use these terms: semiautonomous organelles, symbiotic relationship, protoeukaryote, purple bacteria, cyanobacteria, mitochondria, and chloroplasts. Through research it was…
