concentration of the extract proved to have a better effect on the pond organisms like the breaking apart into thin sheets and scattering of the bacteria‚ the bloating of the size of the filamentous algae‚ and the transverse binary fission of the paramecium and thus stating positive for microbiocidal. With the use of sunflowers in the growing medical society today‚ these can used as alternative sources for antibacterial‚ anti-protozoan‚ and anti-algae‚ so that people won’t have to spend too much

With the GOP nomination only a few weeks away‚ the competition is getting easier and tougher simultaneously. It is easier in the sense that there are less candidates. From the popular candidates in the beginning that lost their lead to the candidates that never actually had much of a chance‚ there has been a pretty significant decline in the number of candidates‚ and thus‚ competition. It’s easier to compete against a smaller number of people and dedicate resources to that problem than it is to dedicate

Option F: Microbes and Biotechnology Diversity of Microbe F.1.1 Outline the classification of living organisms into three domains. Three domains of living organisms: 1. Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases

However wastes are excreted directly from their cells since they have constant contact with the external environment. • The greater challenge for simple organisms is maintaining a fluid balance with their external environment • An example is paramecium: o If they are not able to maintain a fluid balance they would continuously absorb water from the environment and eventually burst o To expel excess water‚ these protozoans have contractile vacuoles‚ which pump out water to maintain osmotic balance

Experiment 1- Title: Observing Bacteria and Blood Purpose: The purpose of this experiment is to learn how to use a compound microscope and an oil immersion lens while observing prepared bacterial slides. Additionally‚ it will be necessary to prepare slides so as to observe bacterial cultures from yogurt as well as to observe the composition of blood (i.e. red blood cells‚ white blood cells‚ and platelets). Procedure: Exercise 1: Viewing Prepared Slides To begin this lab experiment I
