differ in the rate of killing fungi? 4. Which oregano extract concentration is most effective in killing fungi? 5. Is there a significant difference between the concentrations of oregano extract on the paint mixtures on the growth rate of molds in the agar medium? Hypothesis 1. Ho: The oregano extract is not an effective additive fungicide for paints. 2. Ho: The extract does not have an additive effect on the appearance of paint. 3. Ho: There is insignificant difference in the rate of killing fungi

Cloning of plasmid pUC19 in E.coli bacteria Introduction One aspect of the DNA cloning experiments that is carefully considered is the selection of cloning vectors. A variety of vectors have been created‚ each being suitable for a particular use. One common vector used in laboratories is a plasmid called pUC19. It is 2686 base pairs long and possesses an origin of replication which allows the production of over 100 copies in a competent E.coli cell. It possesses a multiple cloning site (MCS)

what optimum combination of ingredients would best increase efficiency in soil productivity to equal the result of hydroponics (Cultivation of plants in nutrient solution rather than in soil). Through research our group came to the conclusion that agar‚ pearlite and mulched grass could all greatly contribute to enriching the nutrient of the soil. We predict that one of the treatments‚ using the above listed ingredients‚ will have a greater growth rate than the controlled plant strictly using hydroponics
