do on Earth. Our hypothesis was that the Moon would not be able to inhabit life forms and our hypothesis was correct‚ we were able to show that the Moon was uninhabitable. We had taken a water bottle and filled it with water and sugar‚ then we put yeast in it and got as much air out as possible to give it the no air factor‚ at that point we attached a balloon and watched it get sucked into the bottle. Our results were that at 15 minutes Earth had a circumference of 18.5 cm and 0 cm for the Moon. At

that the substrate will take a longer time to mix with the fluid acids‚ and thus much of the time will be wasted when the enzyme makes contact with the combined substances. Design: In order to do this‚ we will be using the following materials: Yeast Packet (this will be our enzyme‚ which comes from (source))‚ 30 mL 3% Hydrogen Peroxide (this will be our substrate)‚ (2) 250 mL Beakers‚ 3 Balloons‚ H 2 O 2‚ Measuring Spoon‚ Permanent Marker‚ Ruler‚ 30 cm String‚ 3 Test Tubes (Glass)‚ Test Tube Rack

BREAD MAKING TIME LINE Depending on the type of yeast you are using the steps to making bread will vary. Using the basic bread dough recipe‚ this time line is based on using dry active yeast. I am also basing this time line on the straight dough method which is the direct method of making bread. STEP 1 To make your dough‚ your ingredients must be accurately measured and weighed as well as be the appropriate temperature. Wet ingredients are usually weighed rather than measured to guarantee

Most beer is flavored with – Hops= adds bitterness and acts as a natural preservative. Process of beer production= Brewing 1.) Starch is steeped in Water 2.) Produces a sugary ‘wort’ 3.) ‘wort’ is then flavored (most commonly with hops) 4.) Yeast is then used to cause Fermentation 5.) Produces

We hypothesized that the amount of UV radiation exposed has a negative correlation with yeast genetic stability‚ which ultimately determines the number of yeast colonies. In this experiment‚ yeast cells were treated with UV radiation‚ protected by photoprotective agents with different strength (in ascending order: Sunscreen #2‚ #1‚ aluminium foil). After letting it grow for seven days at 37 degrees‚ some grown colonies were counted to determine the effectiveness of photoprotective agents. After comparing

creating error for obvious reasons. The validity of the experiment could also have been improved if the fermentation was recorded over a longer period of time‚ further research suggests that a minimum time of 45 minutes is ideal when waiting for yeast fermentation. A longer period of time may have allowed for the water in the beaker to heat or cool the flasks more effectively and create a more accurate response‚ especially as it was assumed that the temperature in the beaker would be the same temperature

the gas pressure sensor. By calculating the difference of the gas pressure divided by the amount of time from the raw data collection it is able to find the rate of reaction of the decomposition of hydrogen peroxide. * Control Variable- 1mL of yeast (catalyst) is being used in every trial. The volume of H2O2 is always 4 mL‚ even though the concentration changes and the sizes and type of test tube was the same because it can change the pressure. * Independent Variable- Concentration of H2O2
