Gelatin

Contribution to science Koch has contributed a lot to science; however his most famous contribution is his discovery of mycobacterium tuberculosis, which proved the idea that tuberculosis was not an ‘inherited disease’ (as it was thought at the time) but a bacterium, and was infectious (a scientist named Villemin demonstrated its was contagious but had no solid evidence to back him up). To prove that his theory was correct, Koch used a test which he had devised in his study of anthrax (now)…

Orcas are unable to hunt and obtain water from their prey in captivity. SeaWorld gives them gelatin, a substance that is not natural for them, in an attempt to keep them hydrated. Gelatin is a protein obtained by boiling skin, tendons, ligaments, and bones with water. It is usually obtained from cows or pigs. (“Diet of Pig and Cow Bones”) Tilikum the whale, who weighs 12,000lbs, alone consumes 83 pounds of gelatin everyday…

I do not believe that there is any real concern for contracting prions/Mad Cow Disease or Creutzfeldt-Jakob Disease from Altoids. I believe this to be true because of many reasons, one being that the transmission from one species to another, while highly possible is less successful on the prions part than from one animal to another of the same species. “The transmission of prions from one species to another is accompanied by a prolonged incubation time on the initial passage to the host, with…

why I’d want to place gelatin in an ice bath after incubation, but now I see the answer is obvious: incubation will liquify gelatin which can give a false positive…

Not accurately cutting the agar gelatin to the desired shape can cause diffuse to take longer or shorter depending on the size of the model. In order to prevent these mistakes, one must increase the size measurement of the potato from one millimeters to two millimeters in order to avoid…

left children to fend for themselves, but for the resolute, these defining moments have stood the test of time as photographs captured by Lewis W. Hine and Arthur Rothstein. Captured by the American artist Lewis W. Hine in 1905 and later printed on gelatin silver print in 1939, Italian Family, Ellis Island depicts a family of four anxiously waiting their…

Silver nitrate is a compound with many practical and non-practical uses. Like many other compounds, it is very helpful in discovering the many reactions that lie in our seemingly endless periodic table of elements. A few of the categories that utilize this compound are, laboratory work, manufacturing, biology research, medical history, photography, and even the art of ceramics. Silver nitrate has been known by scientists worldwide to be very helpful in detecting the presence of Chlorine,…

just what everyone ate until I started going to school and noticing other kids lunches, and they started to notice mine. But at the heart of my semi-Russian experience there are four foods that seem to best capture the ideal Russian dishes. • Aspic gelatin • Cow tongue • Hunter bacon • Cabbage roll Now of course I could go on with lots a delicious Russian dishes such as pelmeni, and shuba, and blin, and oh my gosh I complete forgot to have lunch. Each of those dishes gives a better…

Gram Negative Unknown Lab Report #20 BIOL 3444-008 Giang Nguyen TA: Malini Kotak 11/05/2014 Abstract The experiment is conducted in order to identify a randomly given unknown gram-negative microorganism. By comparative analysis of biochemical tests that were performed throughout the semester to find out its characteristics and determine the identification of bacterium out of four potential unknown was given. To figure out the characteristics, T-streak was performed to isolate…

Bromelain is cystein protease or an enzyme mixture coming from pineapple. Although bromelain is found in every part of the pineapple, it's most plentiful in the stem. This enzyme has low but significant activity at 0°C, which dramatically increases at 50-70°C. The activity is sustained without a marked decrease up to 80°C. Bromelain is quite effective at dividing proteins such as the collagen in steak. Bromelain first degrades 40% of the collagen in the sarcolemma followed by degradation of…
