Organism

selection is when organisms that are most suited to the environment survive and reproduce more successfully. Certain colored bead bugs would survive longer, because they blended in. The bead bugs that are a more prominent color stood out more and were eaten right away. This experiment displays how the population of bead bugs changes over the generations, due to the amount being eaten and the amount of bead bugs that were reproduced. Theory Evolution is “the process by which organisms have changed over

deepest hyper-saline lake of the Dead Sea to the hydrothermal vents along mid-ocean ridges in the Pacific and even the nuclear radiated wastelands of Chernobyl. In these extreme environment where humans generally can’t live or would die there, organisms known as extremophiles flaunts life’s ability to exist inside the harshest of environments. In mankind’s quest to venture deep into the harshest of geophysical and geochemical environments which would seem detrimental to most life on earth, research

The energy sources an organism’s uses can also be determined to classify the metabolism of the unknown organism. For instance, the ability to use citrate as the sole carbon source can be assessed by growing cells in a medium with citrate as the only carbon source and a pH indicator that which changed color when the pH increases as a result of citrate metabolism (7). Similarly, the indicator methyl red can be added to a medium containing the unknown sample and various carbon sources. If the sample

this class we have learned lab technique and how to do a variety of different tests on bacteria. Microbiology is not only an academic understanding of microorganisms but learning how to practically use lab procedures to properly identify and test organisms. There are several reasons one might need to identify a bacteria. It could be to find out the causative agent in a patients disease or to figure out the antibiotics that need to be administered. This project was for students to use the knowledge

to individual due to differences in diet, genetic factors and environment. The organisms that exist in a gut microbiome within a certain organism plays many roles, such as aiding with food digestion, gut barrier function and wound recovery. While diet has been believed to play a large factor in internal microbiome composition, we do not have the evidence to support this fully. Thus using non-human model organisms could help address the question at hand by altering diets and looking at subsequent

contain organisms called protists. Most Protists are often described as simple organisms; however, their cellular organization and metabolism are as complex as other higher organisms (McGraw Hill, 2017). Therefore, comparing between three of these supergroups will make us understand their classification in that specific group. Paramecium, Amoeba, and Euglena are three eukaryotic organisms that can be interesting to compare them for several reasons. One of them is that these three organisms cause the

What is Evolution? Evolution is the modification of characteristics of living organisms over generations (StrangeScience.net, 2015); it is the gradual process of development by which the present diversity of living organisms arose from the earliest forms of life, which is believed to have been ongoing for at least the past 3000 million years (Hine, 2004). Common ancestry are groups of living organisms that share the most recent common ancestor, by which scientific evidence proves that all life on

What is ageing: According to the oxford dictionary, ageing is the process of change in the properties of a material occurring over a period, either spontaneously or through deliberate action. In biology, the term Senescence is used, which describes biological ageing. Each cell in the human body experience stress and damage from exogenous and endogenous sources. These cells then respond, in a manner, which could lead to cell death or cell recovery. This is where ageing comes into play, where

Introduction: An organism of unknown origin was selected by the course instructor in an effort to properly identify the organism with the utilization of a series of biochemical tests. This exercise was of extreme importance during the termination of the course because it was essential that each student be able to apply the practical knowledge learned through class lectures, and lab practicals in an effort to individualize such experience so that each student could properly handle a bacterial culture

record of life existing anywhere else in space. All of the organisms that inhibit the biosphere impact it in some way. However, humans have the largest impact on the biosphere through the means of industrialization, reproduction, and consumption. As with all of the other organisms inhibiting the biosphere, humans have basic needs in order to thrive. We need habitats, protection, reproductive success, and sustenance. However, unlike other organisms, we have proclivities that span beyond the essential tools
