Unable to read the Gram Stain at first it was later confirmed that Unknown #7 was a gram negative bacteria. When introduced to Starch Unknown #7 produced no zone of clearing showing that it did not contain the enzyme amylase. When introduced to the Lipid Unknown #7 did produce a zone of clearing indicating that it did contain the enzyme lipase. When introduced to Casein Unknown #7 produced no zone of clearing indicating that it did not contain the enzyme protease. When streaked onto the Gelatin‚

____________________ ABSTRACT The effect of molecular weight on the diffusion of substances were tested through the use of agar-water gel with three wells placed in a petri dish. Drops of three different substances namely: Potassium permanganate (KMnO4)‚ Potassium dichromate (K2Cr2O7) and Methylene Blue were placed in the wells of the agar-water gel in the petri dish. The diameter of the diffused substance was noted every 3 minutes for 30 minutes. The Potassium permanganate (KMnO4)

quickly diffusion occurs is dependent on several factors‚ such as temperature‚ particle size‚ and the concentration difference on either side of the membrane. Testing the hypothesis relating to the effect of molecular weight to the diffusion rate‚ agar plate set-up was used to observe the diffusion of different substances. The methylene blue and potassium permanganate (KMnO4) was used and placed in the plate. Because the two substances have distinct colors‚ the measurement of the diffusion zone was

CHIANG MAI‚ Thailand — Sex work is seen as a taboo subject by much of Burmese society‚ but over the border in Thailand‚ Burmese migrants make up a large share of male sex workers. In the northern Thai city of Chiang Mai‚ Burmese migrants sell their bodies for sex at “show bars” or other entertainment venues. The bars are legal‚ but it is illegal for migrants to work at them. As a result‚ many male sex workers do not seek medical assistance if they contract sexually transmitted diseases because

The Results from the Gram positive tests indicated that the unknown #4 was Streptococcus pyogenes. All seven tests on the unknown matched S. pyogenes perfectly. The blood agar plate proved the unknown to be β hemolytic‚ meaning the unknown bacteria was capable of complete hemolysis. This test separated the unknown into the β Streptococcus group‚ narrowing the possible bacteria to S. aureus or S. pyogenes. The Catalase test was used to determine if the unknown could break down hydrogen peroxide

he root system is developed in the soil since soil can help establish their strand and protect the fragile roots from stressful conditions such as drought‚ nutrient deficiency‚ unfavourable temperature‚ etc. Hydrotropism is a directional growth response exhibited in terrestrial plants in which water or water vapour is the orienting stimulus. In hydrotropism the root caps perceive and respond to moisture gradient of the soil simultaneously which will then regulate the directional growth of the root

X – 4L March 24‚ 2015 ABSTRACT The effect of molecular weight and time on the rate of diffusion was determined using the agar-water gel test. A petri dish of agar-water gel with three wells was prepared and a prepared solution of each substance was dropped on each well; one with potassium permanganate (KMnO4)‚ the other with potassium dichromate (K2Cr2O7)‚ and the last one with methylene blue
