Saphire‚ 2009) Ebola-Zaire and Ebola-Sudan are the most lethal with mortality rates upwards of 90% and 61% respectively. (CDC.gov) Ebola virus is classified as a Class A bioterrorism agent and one that must be handled bio- safety level 4 labs. Research of Ebola virus requires trained professionals and facilities with rigorous levels of control to access. (CDC.gov) Like other viruses‚ the survival and spread of Ebola is dependent upon the host organism. At this time‚ the natural reservoir

Desalination of Seawater Project Paper The main concept of this Desalination process is reverse osmosis‚ but we will get into that later. Right now what is probably running through your head is what exactly is desalination. To put it simply desalination is the process to make seawater or otherwise undrinkable water safe to consume. This can be accomplished through a variety of methods such as the simplest but one of the ones that requires a lot of money would be distillation. Distillation is commonly

Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your

Title: The effect of temperature on beet cell membranes. Introduction: 1. Eukaryotic cells are much more intricate than prokaryotic cells. The first thing observed is the assortment of structures in the cytoplasm. The fluid filled region between the nucleus and the plasma membrane. These structures along with the nucleus are the organelles‚ each having a specific function in the cell. The organelles are by membranes divided in proficient sections .The plant cell is made up of a rigid thick wall

Objectives: 1. To demonstrate the principle of Osmosis and to apply it with actual life situations. Materials and Methods: • Materials: Compound microscope Glass Slide Cover Slip Tissue Paper Blade Rhoeo discolor Leaves Salt Solution • Procedures: Place a drop of distilled

The Effect of Osmosis on The Mass of Eggs Victoria Vu Biology October 22‚ 2013 Introduction & Hypothesis The membrane of an egg is composed of keratin (a type of protein)‚ which is semipermeable. This means only certain materials will be allowed to enter and exit through the egg’s membrane. The purpose of this experiment is study the process in which water molecules pass the egg membrane‚ osmosis. This experiment also gives insight on how other ‘semipermeable membranes’ work‚ like a

TRIPLE SUGAR-IRON AGAR TEST Triple sugar-iron (TSI) agar test- designed to differentiate among the different groups or genera of the Enterobacteriaceae‚ which are all gram-negative bacilli capable of fermenting glucose with the production of acid a. Differentiation is made on the basis of differences in carbohydrate fermentation patterns and hydrogen sulfide production. To facilitate observation of carbohydrate utilization patterns- TSI agar slants contain lactose and sucrose (1%) concentrations

The process of osmosis and its importance to living organisms Osmosis is the process by which there is a net movement of water through a semi permeable membrane from an area of high water potential to an area of low water potential. Within a cell‚ osmosis has the following effect. If the water potential of the cell is lower than that around the cell water will move across a concentration gradient into the cell. If this is the case‚ the increase in water in the cell‚ may cause the cell to swell

I did not learn my communicating skills until I took my microbiology class. I had to do a project on sexual transmitted diseases (STD) and it required meeting after class. Being shy and not confident enough‚ I didn’t want to meet my group. Dr. Nande called me one day because some of my group partners complained to him. I stood in front of him looking down nervously on what he was going to say. He read my body language and just said that I can either tell him what the problem is or I can take a zero
