Now‚ despite arguments to the contrary made by food manufacturers‚ they may well be more nutritious for a variety of reasons. There are always studies available to prove any point‚ especially one

Introduction:The objective throughout the gram staining experiment was to classify bacteria through their chemical nature as well as the physical structure of their cell walls. Through this experiment one would be able to observe either a thick or thin layer of peptidoglycan by the appearance of the bacteria staining either gram-positive blue-purple or gram-negative pink. Question: Is there a subsequent effect of the bacteria when decolorizing with alcohol? Hypothesis: If there is either a removal

In the case of bacterial meningitis no one casual organism causes all of the cases‚ but rather there are many that capable of causing it. Although there are many causal organisms‚ there are three that are most prevalent in cases diagnosed. Streptococcus pneumoniae is the most common causative agent in the Untied States causing 30-50% of all cases. In recent years many strains of S. pneumoniae have become drug-resistant which makes treatment very difficult and increases the mortality rate. Neisseria

human tooth ‚ tooth decay [pic] Human tooth Teeth of humans are small‚ calcified‚ whitish structures found in the mouth that are used to break down food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums. Teeth are made of multiple tissues of varying density and hardness. Teeth are among the most distinctive (and long-lasting) features of mammal species. Humans‚ like other mammals‚ are diphyodont‚ meaning that

running head: UNIT 10. ASSIGNMENT Environmental Microbiology With so much advertising for various antibacterial products‚ many people have gotten the impression that all bacteria are harmful and that maybe the Earth would be better off if all bacteria were eliminated. What would life be like in a bacteria-free world? Bacteria help decay materials and put vitamins and minerals‚ and gases into the atmosphere. Without them the world would be able to produce little food. Bacteria are woven into

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

WHY I CHOSE THE PROJECT? This project has been chosen in view of increasing demand of milk and also due to higher expectations of good quality and low fat diet requirements of the people with better awareness. Also the requirement for such quality products is more acute today. In this project I have prepared soy milk from soyabeans and have compared the conditions of formation of good quality cow milk yogurt and soy milk yogurt. I have also tried to find the effect of temperature on the pH of
