affects the activity of amylase enzyme and the optimal temperature for fungal and bacterial amylase‚ the activity of these enzymes were tested at different temperature and times and iodine was used as indicator of presence of starch. During the experiment we observed that bacterial amylase had faster enzymatic activity than fungal amylase; bacterial amylase achieved 100% hydrolysis at 40°c and 60°c at 2 minutes time and fungal amylase achieved partial hydrolysis at 60°c at 4 minutes time.

Amber Stout Pd. 6 Invasive Species Do you know how many invasive species there are in Hawaii? There are over hundreds and they are disrupting and damaging our ecosystem costing us millions of dollars to repair. Invasive species are a major threat to our environment and we need to stop them before they take over. Here are a few Invasive species in Hawaii. The Hypnea Musciformis (also know as Hookweed) is a reddish brown seaweed that has large hooks at the end of its branches

Keystone species are extremely important in ecosystems across the world. They help control things like population‚ abiotic and biotic life‚ and impacts on human life. Keystone species essentially control the functions of the environment they live in‚ and provide positive and negative effects. In class‚ we studied the effect that wolves had on the environment of Yellowstone National Park. Now‚ I introduce Grizzly Bears and Beavers as my two examples of a Keystone Species. Beavers completely change

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

What is it?Lactobacillus is a type of bacteria. There are lots of different species of lactobacillus. These are "friendly" bacteria that normally live in our digestive‚ urinary‚ and genital systems without causing disease. Lactobacillus is also in some fermented foods like yogurt and in dietary supplements.Lactobacillus is used for treating and preventing diarrhea‚ including infectious types such as rotaviral diarrhea in children and traveler’s diarrhea. It is also used to prevent and treat diarrhea

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

tablets. In the experiment they first tested how long an Alka-Seltzer tablet would dissolve in cold water ( 9 degrees) then repeated it two more times in order to calculate a mean. Then using a hot plate to heat the water‚ they tested another tablet in the hot water (51 degrees) to see how long it would take to dissolve and again did it two more times to calculate a mean. Finally they tested another tablet in water left on the hot plate for thirty-seconds (81 degrees)‚ preformed the experiment for two more

1. Decodable Text * There are five levels of decodable text‚ ranging from highly decodable to minimally decodable. Highly decodable books use one-syllable and one-vowel-sound words‚ such as “cat‚” “fun” or “sit.” These might also use some short sight words‚ such as “a‚” “an” and “the.” Very decodable text still uses simple words‚ but those words may now have an extra letter or use blends that the students are learning in class‚ such as “this‚” “such” or “that.” Decodable text adds more of

Invasive Species Threatens the Ecosystem Every life form all over the world depends on the ecosystem for its survival. However‚ the ecosystem can be threatened when there is an excess or drop in resources. Many people will argue that human beings are the primary cause of this economic imbalance‚ but are people the root of this problem? No. There is evidence that many invasive species all over the world has also threatened the ecosystem. All organisms have the potential to become invasive
