Conclusion In this experiment I tested different light intensities. I tested a normal fluorescent light bulb‚ a 100-watt light bulb‚ a 25-watt light bulb‚ and a 15-watt light bulb. I was surprised to find that the control plant grew the most at 135 mm. The 100 watt plant grew the least at 0 mm due to the fact that it fried the plant. The 25 watt plant grew the next highest at 120 mm. The 15-watt light bulb grew tall fastest‚ but then slowed down and stopped at 98 mm you would want to use this

Fan Cart Lab We did a fan cart for our physics class the other day. To set up the lab first‚ we measured the effect of the mass of the fan cart on the acceleration of the cart. The mass of the fan cart was the independent variable and acceleration was the dependent variable. We kept the speed of the cart on medium‚ and calculated the acceleration and motion. As a result‚ we had figured out that the bigger the mass the slower the acceleration‚ as we all should have known. To calculate this we used

2.3 Results 2.3.1 The Effect of O. lybicus Population on Palms Temperature Over Time Temperature differences between different O. lybicus population levels were not significant in leaves and fronds (P > 0.05). However‚ high significance difference in temperature were occurred over time (P < 0.001) in both parts Figure 1 and 2. The temperature at the highest population (1000 insects) were the highest at the first three weeks‚ before it starts declining gradually (figures 14-15). Chlorophyll measurements

Treating Starch How are starch and cellulose treated to allow them to be used in yeast? Starches: · All potable alcohol and most fermentation industrial alcohol is currently made principally from grains. · Fermentation of starch from grain is somewhat more complex than fermentation of sugars because starch must first be converted to sugar and then to ethanol. · Starch is converted enzymatically to glucose either by diastase presents in sprouting grain or by fungal amylase. · The resulting

Ideal Temperature for junket Aim- To discover the optimum temperature for junket to solidify Hypothesis- That the optimum temperature will be between 35-40°C Independent variable- Temperature (10‚ 40‚ 60 degrees) Dependant variable- Time taken for Junket to set Control- 2 clearly marker test tubes will be placed under each temperature condition‚ one with junket and one without‚ to clear the complication that it might be the temperature that is reacting with the milk and solidifying it instead

Dialysis of starch‚ glucose and sucrose Introduction: Research question: Does the dialysis tube only allow certain substances to pass through the pores because of their size? Dependent and Independent variables: Independent variables: The temperature of the classroom The size of the molecules The size of the pores in the tube The concentration of the indicators Dependent variables: The substance will either pass the pores of the tube or not The result will vary in darkness (color) Controlled

FOOD LAB Title Food Lab Abstract The aim of this report is to see if the any of the four food apple sauce‚ carrot juice‚ cracker juice‚ and turkey juice contain protein‚ starch‚ or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice. Protein is its own organic molecule and only one food tested positive

a negative result. To explain‚ both DI water‚ and sucrose alone do not contain a trace of protein. In addition‚ deionized water is commonly used in experiments as a negative control. In both experiments‚ if the DI water is tested for a protein or starch‚ then it will come back as a negative. If milk solution‚ and 50% egg white solution are tested for proteins using the biuret solution‚ then there will be positive results because both of these are composed of protein macromolecules.

Each enzyme has it optimum temperature range at which it functions at an optimum efficiency. In this experiment‚ Rennin might have an optimum temperature of 37 degrees Celsius as it is found in the stomachs of young mammals. As the temperature is increased‚ the rate of reaction (time for milk to curdle) will also increase until the optimum temperature is reached (37 degrees). After reaching this set point‚ the activity of the enzyme will gradually begin to decrease and the rate of reaction will
