Review of Literature The question being asked here would be “Does a plant grow bigger if watered with milk? Or water?” In my opinion the answer would be milk because milk contains vitamins and calcium that water does not have‚ but the answer is to be found out later during the project. Well‚ it is known that for a plant to survive it will definitely need air‚ soil‚ water‚ light‚ and space to grow‚ but maybe if we replaced water with milk‚ plants could grow bigger and quicker‚ you never

Determination of the presence of carbohydrates and protein in aqueous solution samples Objectives To determine the presence of starch‚ glycogen‚ reducing sugar‚ peptide‚ and proteins by utilizing Iodine test‚ Benedict test‚ and Biuret test. Introduction The purpose of this experiment was to identify the presence of macromolecules by using various positive and negative controls. The principle building blocks of living organisms are essentially constructed by carbon-containing

1. Outline the Steps of DNA: a. DNA Replication begins at the Origin of Replication b. Helicase cuts hydrogen bonds and separates DNA in half c. Semiconservative replication produces two copies that each contained one of the original strands and one entirely new strand. d. Topoisomerases catalyze and guide the unknotting of DNA e. Single Strand Binding Proteins attach to the halves and keep the DNA molecules separated (they are needed because the sides are attracted to each other and with out

bacteria‚ dead cells and mucus from the lining of the intestine‚ and protein. The odour of feces is a result of the decomposing bacteria. These bacteria produce poor smelling compounds such as sulphur- or nitrogen-rich organic compounds such as indole‚ skatole‚ and mercaptans‚ and the inorganic gas hydrogen sulphide. In most instances

Requirements for Unknown Report You have been provided a mixed culture (a gram positive and a gram negative) from which you should have isolated each type of organism‚ described their colonies on a TSA plate‚ and described their cellular morphology. You were graded on this activity separately. After you have isolated your gram negative in pure culture you will be subjecting it to various biochemical tests and making observations about the cells‚ colonies‚ growth temperature preferences‚ etc. in

The strain exhibited positive reactions for catalase‚ oxidase‚ βglucosidase‚ and esculin hydrolysis. Strain N-5 was negative in glucose acidification‚ O−F test‚ indole production‚ arginine dihydrolase‚ urease‚ gelatin hydrolysis‚ lysine decarboxylase‚ and tryptophan deaminase. In assimilation tests using API 20 NE among 12 carbon sources tested‚ growth of strain N-5 was observed only in the presence of glucose‚

Enterobacteriaceae family. It is a small gram-negative Rod‚ and a facultative anaerobe‚ lastly‚ it is a Prokaryote. Furthermore‚ Proteus mirabilis is characterized by its swarming motility‚ its ability to ferment maltose‚ and its inability to ferment lactose. P. mirabilis has the ability to elongate itself and secrete a polysaccharide when in contact with solid surfaces‚ making it extremely motile on items such as medical equipment (catheters). Moreover‚ Proteus mirabilis is part of the normal flora of
