Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and

Griffith’s experiment‚ reported in 1928 by Frederick Griffith‚[1] was one of the first experiments suggesting that bacteria are capable of transferring genetic information through a process known as transformation.[2][3] Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice – a type III-S (smooth)

The Holy experiment William Penn holy experiment is to create a colony on the principle of self-government‚ religious toleration‚ and brotherly love. William Penn make a government which can run with the law of the people. Pennsylvania first constitution organized the government into three parts: the governor‚ the seventy two member of provisional council‚ and general assembly with two hundred member. While the proprietor held his office by hereditary‚ the council and assembly were elected by the

This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

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

RESEARCH DESIGN What is research design? A research design is the arrangement of conditions for collection and analysis of data in a manner that aims to combine relevance to the research purpose with economy in procedure. Research design have following parts: * Sampling design * Observational design * Statistical design * Operational design Sampling designs Which deals with the methods of selecting items to be observed for the study. Observational design Which relates

Unfortunately‚ we did not have any data for week four due to the Astros parade‚ and during the fifth week of data collecting‚ two nightcrawlers went missing during the experiment in one of the containers‚ so the results for the Gain at 0.06% were inaccurate and the six week mass count as shown in figure one‚

community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman et al. 2014). The fermentation of the soy sauce brine revealed that the primary bacteria
