What are Coliform bacteria? : Gram negative non spore forming bacteria that are capable of fermenting lactose to produce acid and gas. What fecal coliform bacteria is used as an indicator species? : E. coli. (If E. coli is present than this suggest that serious pathogens such as Salmonella and Campylobacter species are also present as well.) Does every food from the FDA get tested? : No, unless an outbreak occurs What are the most common bacteria present in milk? : Lactobacillus, Mi...

Describe the selective and differential properties of mannitol salt agar (MSA) for the isolation and identification of staphylococci. - As a selective medium, MSA has a high concentration of salt (7.5% NaCl), which is inhibitory to most bacteria other than the staphylococci. As a differential medium, MSA contains the sugar mannitol as a substrate for fermentation and phenol red as a pH indicator to detect the production of acid. S. aureus ferments mannitol and changes the color of the mediu...

3 Levels of biodiversity genetic: measure of genetic variation of individuals in a population (smallest level of biodiversity, the larger the pop = larger genetic diversity, more diverse has better chance at adapting, precondition for evolution by natural selection) species: # of species in a defined area (most common) ecosystem (habitat): variety of dif habitats, communities, and ecological processes; largest scale (natural prairies, forests. rivers, lakes) why each level of biodivers...

In the nitrogen cycle, which of the following steps involves removal of nitrogen from the atmosphere by bacteria? Nitrogen Fixation If enough H+ ions are added to pure water to raise the H+ concentration of the solution to ten times higher than the original concentration, what is the resulting OH- concentration of the solution? 10-8 M Fungi are able to reproduce asexually by creating conidiospores and sporangiospores. Which of the following is an accurate explanation for why it is advantag...

Conservation International (CI) identified 25 biodiversity hotspots as areas harboring especially large numbers of A. threatened and endangered plant and animal species. B. endemic animal species combined with low rates of habitat conversion. C. plant and animal species. D. endemic plant species combined with high rates of habitat conversion. D CI's hotspots harbor at least 2,500 endemic plant species and have lost at least 70% of their original vegetation due to land conversion. Some conserv...

3 Keys for Life on Earth - 1.) One flow of high-quality energy from the sun 2.) Nutrient cycling 3.) Gravity Affluence and Environmental Degradation - disproportionate difference in resource use between developed and developing countries Angiosperms - seed producing plants that have flowers and produce fruit whcih contain seeds Autumn Olive - invasive shrub, aggressive during sucession has edible berries Biodiversity - variety of life forms/species and the genes they contain, variety of e...
