of biodegradable plastic‚ including polyesters‚ polyhydroxybutyrates‚ vinyl polymers and starch-based polymers. [Garthe‚ James W.‚ and Paula D. Kowal] In this essay‚ the use of plastic made from polylactic acid or PLA (a kind of starch-based polymer) will mainly be discussed‚ because they are one of the most commonly used and cheapest-costing of all biodegradable plastics. PLA is made from the starch in corn (or sometimes wheat) plants‚

How do pill bugs adapt to the different environments as far as (wet‚ dry‚ hot‚ cold‚ light‚ dark‚ etc.) III. Background This lab has to do with ethology which is the study of an animal’s behavior‚ and it has two categories: learned and innate. We focused in on the orientation behavior which showed which environments the pill bugs favored. Kinesis is a random movement in which the organisms

• Carbohydrates include simple sugars‚ disaccharides and polysaccharides. They are the most important source of energy for most organisms. Polysaccharides change color in the presence of iodine solution: Glycogen gives a red-brown color and starch a dark blue–violet color. While simple sugars‚ having an aldehyde group‚ or a ketone group act as reducing agents in the presence of Benedict’s reagent producing a range of colors from green to brown depending on the degree of reduction they exhibit

The substances that could be found were iron‚ cinnamon‚ corn starch‚ baby powder‚ copper‚ and strontium. A magnetism test was used to determine whether iron or cinnamon was contained in the substance. An iodine test was used to indicate whether corn starch or baby powder was contained in the mixture because it is an indicator. An indicator is a substance that undergoes a distinct observable change when conditions
