The hypothesis was rejected in this experiment‚ based on the results. The results were much different than hypothesized before the experiment. It was hypothesized that the lower concentrations of CLR‚ Jar E and Jar D‚ would be healthier and more likely to reproduce than the higher concentrations of CLR‚ Jar B and C. However‚ as shown in the actual results‚ Jar E and D with the lower concentrations of CLR died quicker than Jar B and C. The CLR and water solutions acted as a fertilizer‚ so the greater

pathogen is a tiny non-visible disease causing microorganism such as Bacteria‚ Virus and Fungus. Both the scientific name and common name for Actinomycosis is Actinomycosis. The pathogens that cause Actinomycosis are from a species of Actinomyces‚ most commonly known as Actinomyces Israelii and Actinomyces Gerencseriae. The species of Actinomyces are an Actinobacteria class of Bacteria. The pathogens are endogenous‚ meaning the bacteria originate from inside the body‚ making them not liable to be transmitted

The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and‚ through a series of metabolic tests‚ identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45‚ henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment. From the streak plate‚ several slides were made to determine the morphology of unknown 45. A Gram stain

Sustainability (a) A bottle of milk purchased in Christchurch is very like to be produced in the South island‚ either in Canterbury or Southland‚ which are the main dairying areas. The production process for milk: From the farm: milk is produced from grass‚ dairy cow’s graze on the grass and then they are milked twice a day using mechanical vacuum milking machines. The raw milk flows through stainless steel pipes to a refrigerated bulk milk tank. The milk is collected by road tanker every one

cellular respiration is oxygen and carbon dioxide. The process of cellular respiration is releasing energy from sugars using oxygen and the product is carbon dioxide and water and in the process‚ ATP is made that can then be used for cellular work. Oxygen is needed to be absorbed from the environment and into the organism’s blood so it can be transported to respiring cells. Carbon dioxide must be released into the environment from the organism’s blood. The formula for cellular respiration is:

Coccus is a term used to describe a type of morphology that helps us distinguish different kinds of bacteria. The cell’s morphology is only one of the many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium

Photosynthesis and cellular respiration play significant roles in existence of all living organisms on the planet. Supplying energy to the cells they carry out is the main process called life. Photosynthesis is the process by which several living organisms such as plants and bacteria utilize sunlight and several raw materials such as carbon dioxide and water to produce sugars and release oxygen into the atmosphere. It does not only supplies oxygen which required for human life but it is also the

Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However‚ in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration‚ we need to understand what
