step 2: The hypothesis Answer the following questions: * What is a hypothesis? * How is a hypothesis different from a theory in science? * Describe an example of how you may use the scientific method in your daily life and state a good hypothesis for that example. * Which hypothesis did you first pick in the "Recognizing a good hypothesis" activity in the scientific method tutorial? Why? If any‚ which mistake(s) did you make when picking a hypothesis? A hypothesis is a specific

ANALYSIS OF BACTERIA GROWTH Abstract Bacteria can be found everywhere on the earth. Bacteria are single-celled organisms that lack a nucleus‚ mitochondria‚ and chloroplasts and are surrounded by a cell wall containing a peptidoglycan layer. They are defined by their small size and wide range of shapes. In this experiment we separated organisms in a mixed culture to study the colony morphology and physical characteristics and determine which organism was present in higher numbers‚ as determined

Observing Bacteria Kelli Jo Simco Microbiology Due: 2/8/13 Abstract: Microscopes are fragile instruments that must be handle with extreme caution as they can produce high quality results when observing the smallest specimens on earth. A microscope must be properly cleaned before use and storage. The different objectives allow for a range of observations. At the highest objectives‚ the resolution can easily be lost which is why the oil immersion lens is used to minimize refraction. While

Autumn White Biology 258-05 November 26‚ 2012 Unknown #19 Enterbacteriaceae Enterobacter aerogenes ABSTRACT The objective of this report was to identify an unknown microorganism through several differential media tests. Over the course of a couple weeks‚ ten tests were performed. First‚ a gram stain was performed‚ indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next‚ a negative result in the

Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because they are small and because they infect cells. While most bacterial are unicellular they can also exist in colonial or multicellular forms. In this laboratory exercise you will examine the ubiquity and diversity of various microbes that are present in the environment or inhabit the human body. Most bacteria that inhabit the body are

Cheese: A Home to Bacteria “Cheese is just a means of controlled spoilage‚” said Steve Jenkins‚ a Master Cheesemonger at Fairway Market. (Cheese) Bacteria‚ or starter cultures‚ control the flavor‚ hardness‚ type‚ and many more aspects of cheese. The two main strands of bacteria involved in cheese making are Lactococcus and Lactobacillus‚ which ferment sugars found in the milk. Humans have learned to manipulate bacteria and the fermentation process to produce different types of cheese such as Swiss

CHAPTER TWO Beneficial bacteria in the environment and their uses. In today’s world‚ the environment and its related issues are steadily gaining a lot of importance. Some bacteria are helpful and are used to obtain balance in the environment. It has been seen that helpful bacteria are useful in dissolving organic sludge from water‚ breaking down the growth of algae‚ reducing the various noxious odours such as hydrogen sulfide odours‚ reducing ammonia levels‚ promoting faster growth of fish in the
