Unit 22 1.1 Bacteria are a single cell micro-organism that can only be seen from under a microscope. It lives off the nutrients from its surroundings. Viruses are disease producing agents far smaller than bacteria‚ They are enclosed in a protein coating which makes them more difficult to destroy. The basic unit of Fungi is a hypha which is a hollow tube. The hypha threads spread out over and into the food material making a visible mesh or mycelium. Some fungi form together to create toadstools

Title: Chapter 7: Bacterial Growth Purpose: The purpose of this experiment is to observe the bacterial growth of Escherichia coli under various conditions. Physical factors and nutritional requirements determine the overall concentration of the bacteria. Along with the use of a spectrophotometer and the technique of serial dilution‚ countable colonies can be obtained. Results are plotted on a semi-log graph in order to observe the different growth curves corresponding to optical density (cell

Effectiveness of Garlic in Fighting Bacteria Introduction This experiment determined whether garlic was effective in fighting bacteria. This project interested me because garlic is traditionally used in medicine and is known to combat bacteria. Hypothesis If bacteria is exposed to garlic‚ then the garlic will to abolish the Escherichia coli‚ because the Escherichia coli (E. coli) is usually a weak bacteria. Procedure Have three petri dishes prepared with blood agar‚ and three test tubes

Where does it come from? (source? Natural or chemical) Streptokinase is extracellular bacterial protein and it comes from purified strains of group C beta-hemolytic streptococcus. It hydrolyzes peptide bonds and has a non-protease plasminogen activator which activates plasminogen to plasmin. This enzyme is used through its lysine binding site which is used as a medical drug for patients with blood clots. It was originally discovered from a precipitate of salt‚ that was then purified so the active

A. The typical human mouth contains a writhing orgy of bacteria. Most of these. Most of these microscopic organisms are bengin‚ and some are even beneficial‚ but one particular variety is a conspicuous troublemaker: Streptococcus mutans. These ubiquitous bacteria thrive on sugars in the mouth‚ which they consume while excreting lactic acid. This acid is responsible for the great majority of tooth decay in humankind because it erodes the enamel and dentin of the teeth. B. A Florida-based company

Pertussis‚ or as some call it whooping cough‚ is a well-known childhood respiratory infection that is caused by the bacterium bordetella pertussis (CDC). When an individual attempts to inhale air‚ the noise that is produced due to the inflamed and swollen laryngeal structures is where the name Whooping cough originates from. When someone exhibits vomiting while coughing‚ high fever‚ trouble while breathing‚ and or cyanosis they may be affected by pertussis (MedlinePlus). The majority of deaths continue

“Each year‚ on average‚ 5 percent to percent of the US population gets the flue each year.” (CDC Foundation). The organism I chose is Haemophilus Influenzae‚ and the disease that comes from this organism is Influenza. Transmission of this disease is very simple. There are many different diseases that can come with complications of Influenza. The treatments are simple and do not cost much. The prognosis is pretty good for most people. Influenza is a disease that can either be a okay disease to deal

In 1972‚ a Uruguayan Air Force plane has crashed in the Andes‚ leaving members of a rugby team and their families fighting for their survival. Two men from the crash later appeared in Chile‚ claiming to have walked through the Andes and declared themselves as passengers of a plane that fell out of the sky. 16 out of 45 passengers survived over the course of nearly 72 days. The survivors faced multiple challenges as stated in the book Miracle in the Andes by Nando Parrado. Here are some of their challenges
