susceptible to antibiotics‚ but there are a few anti-viral drugs available which are active against a limited number of viruses. Pathogenic Fungi: can be either moulds or yeasts. For example‚ a mould‚ which causes infections in humans‚ is Trichophtyon rubrum‚ which is one cause of ringworm‚ and which can also infect nails. A common yeast infection is thrush caused by Candida albicans. Protozoa: are microscopic organisms‚ but larger than bacteria. Free-living and nonpathogenic protozoa include amoebae

Abstract The catalysis of enzymes within our bodies is essential for human survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze

Yeast Cells Yeast is a single-celled organism. Like bacterial cells‚ yeast cells have cytoplasm and a membrane surrounded by a cell wall. But unlike bacterial cells‚ yeast cells have a nucleus. Specialised cells Cells may be specialised for a particular function. Their structure will allow them to carry this function out. Here are some

The World: As London Sees It The world as a conscious being stupefies some‚ as it is an awesome thought that many people ponder. The thought of the universe as a thing that picks and chooses who lives and dies terrifies some‚ while some welcome the idea and coexist with it. Jack London‚ the author of such books as The Call of the Wild‚ and The Sea Wolf‚ is one such man who lives with the idea. London views the world as a Darwinist‚ or with the theory of natural selection. He sees the world with

Bacterial Morphology MLT1 Task 11- Lab 2 Johnny Archuleta Western Governors University Question A and C answers. A wet mount stain is when a drop of water is placed onto the microscope slide. The water on the slide helps to support the organism and sample. The water fills the space between the cover slip and the slide. This action allows the light from the microscope to pass through the slide and the sample for better visualization of the organisms. A direct stain occurs when a charged

She created a rack that held the bottles of wine upside down‚ an assistant every day would gently shake and twist the bottles to encourage the death yeasts to settle to the bottom. When this was complete‚ the cork would be gently removed and the bundle of yeasts ejected. Now the wine was less cloudy‚ and the bubbles were smaller. It would be years before her biggest
