Dockendorff Bacteria: Communication Equals Modification Bacteria are organisms that are extremely copious upon this planet. They are tiny and most are single celled organisms that can survive in just about any environment. Anywhere from plants to the human body is where these organisms can be discovered. Some of the strangest places that support bacterial life include places that have extremes of temperature. These bacteria are also very strange‚ much different from bacteria found living in

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance equal to

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

How do bacteria affect human lives? Bacteria interact and are a constant in our day to day lives‚ perhaps more than suspected. Bacteria are often thought of as bad‚ however this is untrue‚ there is also many types of ‘good’ bacteria. ‘Good’ bacteria can benefit us by simply helping our digestive system work and helping us in the process of fermentation. Bacteria are extremely helpful in the production of many things such as fuel and medicine. But bacteria directly affect our production of

Virus vs. Bacteria Similarities – Virus vs. Harmful Bacteria Virus and Bacteria are similar. But yet they are different. Viruses and bacteria can make copies of themselves once they are inside a living organism (“J. L.”). They are both harmful bacteria and viruses. These bacteria and viruses can be helpful to the body. All diseases that people get are from virus and bacteria( Microbe Magic). Bacteria and virus are both microscopic organisms that have the same brain structure that why they are called

Explaining Bacteria Alexandra Solorzano 1E “ Hey Alex. Could you help your cousin with his homework?” “Okay‚ but I don’t understand what could be hard about fifth grade homework. Anyways‚ what are you learning about George?” “Well today my teacher started to talk about these things called Blackmeria? Or what is backferium?” “Umm I think you mean bacteria?” “Yeah! That’s it!” “Then I guess it’s your lucky day because right now in STT I’m in Cell Biology and we started to look into Bacteria too. Tell

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured
