17. Press START and turn on the stir bar. 18. After 10 seconds have elapsed, add hot water sample 19. Press STOP when the thermograph stabilizes 20.
2. For the control, add 25 µl growth medium on hyphae with a Gilson pipette and yellow tip and cover with a slip over it. Take note of the time for each slide preparation. 3. Set up Kohler and observe the specimen on the slide with 10x objective lens then move to 40x objective lens, switch from BF to fluorescence.

For that we must put the temperature we found and put it into 1.01(x) + 4.43. 1.01 multiplied by 31.8 plus 4.43 equals 36.59 degrees Celsius. Now that all of our values are ready to be analyzed we can narrow down what the unknown substance is. I started with boiling point there was only 2 substance had a boiling point close to the boiling point that we found pentane and ethyl ether. Next the freezing point which didn’t eliminate either of them.
We have filled in three one hour blocks just as an example. Once you have completed the chart, use the Caloric Activity Calculator to determine your caloric requirements for this 24 hour period. Time of Day|Activities and amount of time for each – List all that you would do in each one hour block of time. Your total activity time for each block should be one hour. If it isn't an hour, then either expand your activities list for that hour or increase your estimated times for each.
Method Measured Response Experiment In this experiment we conducted a measured response experiment with light intensities of 504 Lux, 213 Lux, and 7 Lux. Our control was with 504 Lux as this was daylight intensity. We measured our organism’s rate of movement in 30 seconds having nine replicates for each treatment level, for a total of 27 replicates. We set up our
For example, if a particular isotope has a half-life of 20 yr, and the starting amount of the isotope is 100 mg, how much of the isotope will be left in exactly 100 yr? To solve this problem, we first make a chart containing the information we know. time |0 yrs | | | | | | | |amount |100 mg | | | | | | | | Since the half-life is 20 yr, each time interval in the chart should add 20 yr to the previous interval until the time of 100 yr is reached. time |0 yr |20 yr |40 yr |60 yr |80 yr |100 yr | |amount |100 mg | | | | | | | Since the time represented by each interval is the half-life of the isotope, the amount of the isotope must decrease by 1/2 for each interval. For instance, at the end of the first 20 yr interval, the amount of the isotope would decrease by 1/2 to 50 mg.
Adequate separation will have occurred when the cresol red dye front has moved at least 50 mm from the wells. Gel may be stained either with 1 µg/ml ethidium bromide for 10 minutes or 0.05% methylene blue (or proprietary) stain for 30 minutes, followed by 20-30 minutes destaining with water. * If adding Bromophenol Blue loading dye to sample: do not add the loading dye to the entire sample, leave 10µl of sample without loading dye if you will be sending sample in for
