desired organism or inhibits the growth of competing organisms. Differential Media: Differential media allow for the separation of organisms based on some observable change in the appearance of the medium or by an observable effect on the microbe. Complex Media: A complex medium is composed of a mixture of proteins and extracts in which the exact amount of a particular amino acid‚ sugar‚ or other nutrient is not known. Synthetic Media: In a synthetic medium‚ the exact amount of pure

Biology form 4 – Chapter 5 Mitosis Mitosis is a division of the nucleus to produce two new daughter cells containing chromosomes identical to the parent cell. Significance of mitosis Growth- allows a zygote to produce more cell in order to grow Repair and replacement- allow the multicellular organism maintain its tissues‚ example skin cells and blood Asexual reproduction- clone The cell cycle divided into two major phases a. Interphase b. Mitosis Interphase is the period between division‚ divided

OF agar is used as the nutrient medium and it will turns yellow when cultured with fermentative microbes and only top few mm will turns yellow when cultured with oxidative microbes. B) Starch hydrolysis Not every microbe can produce amylase to hydrolyze starch. This session is to test the ability of microbes for the activity of starch hydrolysis. The presence of blue

Chapter Five‚ “The Problem of Population Growth” What is the basic argument of the Malthusians? What kinds of evidence fail to support their argument? The Malthusian perspective is that as the population increased so did the demand for resources such as food and with that came the prices of items going up since it was in such great demand and Malthus also said that there was no way that disaster could occur. What he failed to see was that as population increased the agricultural techniques

THE AMERICAN STORY NOTES Chapter 1: Native Americans shared different views than the colonizers. (they wanted to bring colonization to North America) They did not agree on punishment of murder. (Europeans and Native Americans) The cultural superiority turned when -- Captain William Claiborne’s trading post in 1635‚ Maryland - Wicomess Indians (they were going to the trading post on business) encountered enemy Susquehannock Indians—they presented inappropriate behavior (making fun) in public

Isolation is separating the microbe that is wanted onto a solid media and inspected further. Identification is the naming of the microbe. In this lab‚ inoculation‚ incubation and inspection are used. Inoculation is used because each TSA (tryptic soy agar) media was placed in a different place to collect cells as
