In this mixture, there are no enzymes present and therefore no products are formed. The reaction rate was rated 0, just as we anticipated. 2. The 2nd experiment was a mixture of 2 mL H2O2 and 0.1g Manganese dioxide. We can use the same principal we used for the first experiment, Manganese dioxide is not a protein, not an enzyme, it is a catalyst.
Surprisingly, the low light intensity has no effect on the plants and according to our data plasticity was not present. Introduction: The purpose of this lab is to examine differences in the characteristics of plants and their environmental responses; specifically speaking, phenotypic plasticity in Pothos aureus petiole lengths to high light and low light treatment. Phenotypic plasticity can be defined as “the ability of an organism to change its morphological and/or physiological features after exposure to different environmental conditions” (Bradshaw, 1965; Schlichting, 1986; Thompson, 1991). The fact that plant are immobile, forces them to adapt to their surrounding and change the structures accordingly. “Phenotypic plasticity is an important adaptation that can optimize plant survival and therefore extend the geographical range over which they grow.”(Ryerson & Dengler, 1994).
The agar plate with the –pGLO LB / amp add no bacteria living in it because it wasn’t ampicillin resistant. But on the other hand the +pGLO LB/amp had a colonies of bacteria because when there is the pGLO plasmid it makes the e-coli bacteria ampicillin resistant so that is the reason why there are colonies of bacteria on the agar plate. For the last agar plate left the +pGLO LB/amp/ara this agar plate is the one that genetically transformed this is the one that could glow under the UV light <Fig 3 bottom right>. The reason that it glowed is because of the arabinose gene on the agar plate, that arabinose gene is the gene that triggers the GFP gene to express
Oil hypothesis accept/reject = Accept, the final result had very little oil in it. b. Vinegar hypothesis accept/reject = Accept, the final result had very little vinegar in it. c. Laundry detergent hypothesis accept/reject = Accept, the final result had a great amount of laundry detergent in it. 3. What affects did each of the contaminants have on the water in the experiment?
The following picture is the purification of the selected colony from the primary plate. This was not a successful streak plate because there are no well-isolated colonies visible. The reason for this is because I did not let the loop cool down sufficiently before streaking. Next I examined my isolated organism by phase contrast microscopy. After examining the isolated unknown organism using the 40X objective with the phase contrast filter, I observed that the cells appear to be rod shaped and non-motile.
MEMO To: Carrie Johnson From: Staff Biologist RE: Bacteria The first step in identifying the mystery organism is to know what kingdom it belongs to. It will belong to one of the following kingdoms: animals, plants, archaebacteria, eubacteria, fungi, or protista. Organisms are placed into these categories based on similarities or common characteristics. Some of the characteristics that are used to determine placement are cell type, metabolism, and reproduction. Examine your living organism and determine if it is a bacteria, achaean or a eukaryote.
Also, here is very clean, and I did not see many trashes like in Vietnam. The moisture was low, so I felt dry and clean all the time. The last thing I like about environment in the US was the locating between living area and industry area. All factories were located far away from houses, schools, and hospitals. This made people have a clean
Oil or Alcoholic base is more effective in Chromatography for separation that could identify the components in Marvel Green. Potential Improvement Chromatography Roll[8] If you have numerous samples that need to be put into one solution and you are using a large beaker, then you can put the samples on one piece of filter paper instead of several strips. Follow the original process but use a big paper instead Roll the big strip and staple the edges (make sure the edges do not touch) Conclusion Although the colour contains similar dyes in colour, they are different substances. In this experiment, many dyes are not separated because of the inefficacy of the H2O base. To analyse the component more deeply and comprehensively, we should conduct in different bases such as CCl4 and C2H5OH.
If you could make a biodegradable plastic bag, you could compost it instead of throwing it away. Scientists used biotechnology to change the genes in potatoes so that they made a plastic instead of starch. The potatoes were harvested, cleaned, chopped up and the plastic extracted. The plastic acted like a normal plastic until it was buried, bacteria in the soil could break it down and rot it away. Consumers didn’t like the feel of the new plastic so it is blended with normal plastics in many items.
The hypothesis was that liquids will not weaken the magnetism of magnets because only magnetic materials block magnetic fields. This hypothesis was proven in the project because the numbers only increased in very small numbers. Therefore, liquids have a very little effect on magnetic
