contrast the similarities and differences among the southern colonies of Virginia‚ Maryland‚ North Carolina‚ South Carolina‚ and Georgia. The new colonies had a lot in common‚ but at the same time most of them had a lot of difference. Most Colonies started off from Virginia and some of them where just completely original. Virginia was founded in 1607 by the Virginia London Company‚ their main crop like most of the other colonies where tobacco and indigo. Their most famous “government” was

Practical 9: Examination of Bacterial Plates Objective: 1. To examine bacteria pigmentation‚ colony‚ margin characteristics‚ elevation properties‚ broth characteristics and agar stroke properties. 2. To examine bacteria growth characteristics on different culture media. Introduction: Bacterial species can sometimes be identified on the basis of how they appear on or in the different media. The pigmentation‚ size and shape of bacterial colonies as they grow on and in agar plates can

the cells. In the following experiment‚ two strains of Escherichia coli bacterial cells (donor F’lac+strs and recipient F-lac-strr) underwent conjugation to produce a transconjugant strain (F’lac+strr). MAC plates and streptomycin were utilized to determine if conjugation had occurred. When plated‚ the donor colonies appeared red and the recipient colonies appeared white. The transconjugant plates showed red and white colonies. Using alkaline lysis miniprep‚ a DNA plasmid was isolated from the donor

Unit 3. Assignment 1: Bacterial Growth Rates 1. Mediums that could be used to determine shigellosis include Btilliant Green Agar‚ and Triple Sugar-Iron Agar. Expected results in a confirmed case of shigellosis are as follows: Brilliant Green Agar – Isolated Shigella colonies which do not ferment lactose or sucrose and appear red or white in color with no growth to trace growth on the Agar plate will be present. Triple Sugar-Iron Agar – Presence of Shigella will manifest as a red slant with

to survive at first. They both also encountered natives living there before they arrived. In Virginia there were the Algonquians and in Massachusetts Bay there was a large number of Puritans. Although there were many differences between the two colonies it comes as to no surprise that they are very much so related in their hardships. Such as in Virginia there was disease‚ famine and continuing attacks of the neighboring Algonquians which took a tremendous toll on the population. Only sixty out of

Bacterial Transformation Lab Introduction: In this experiment we transformed a strain of E. Coli bacteria without antibiotic resistance with plasmid DNA. This plasmid produces a fluorescent green glow under black light due to the gfp(green fluorescent protein) as well as antibiotic resistance. E. Coli cells will be plated on an agar medium‚ some with and some without the antibiotic ampicillin. Only bacterial cells that contain the plasmid will survive the ampicillin and produce the green glow

DBQ Essay In the 1600’s‚ the New England colony devolved very rapidly. The political‚ economic‚ and social development of the colonies was highly influenced by the Puritans‚ who helped find most of the colonies in the region after emigrating there from England. The Puritans strict values and ideas helped shape the colonies greatly in several ways. They believed in a representative government which later on became an essential part of the United States’ government. Economically‚ the idea of fair

calculated the growth curve and it was 1.2. Using this I found the doubling time which was 34s. Introduction Bacteria grows by binary fission. One bacteria becomes two‚ two bacteria becomes four bacteria and it so goes on. A lot of changes occur in the bacterial cell during growth and due to this reason it is difficult to measure growth quantitatively. Growth is therefore usually measure by changing one or two easily measure parameters which will ignore the complicated cellular change. Therefore different

you. Prior to 1700‚ the British North American colonies had conflicting outlooks on the extent of religious freedom in the new world based on the different acts of the British Empire and by the English origin of most of the settlers. New England was mostly comprised of Puritans‚ the Middle Colonies consisted of Quakers‚ and the South was more concerned about using the land to make money and didn’t emphasize on religion. The Southern Mainland colonies considered the Church of England as their dominant

Title: Chapter 7: Bacterial Growth Purpose: The purpose of this experiment is to observe the bacterial growth of Escherichia coli under various conditions. Physical factors and nutritional requirements determine the overall concentration of the bacteria. Along with the use of a spectrophotometer and the technique of serial dilution‚ countable colonies can be obtained. Results are plotted on a semi-log graph in order to observe the different growth curves corresponding to optical density (cell
