You are interested to know the Q10 value for mean heart rate (# of beats/10 sec) for a species of crab for the temperature interval of 25°C - 35°C. To find this value, you collect data for these six temperatures and calculate mean heart rate (# of beats/10 sec) for each temperature. Here is the data: 10°C 15°C 20°C 25°C 30°C 35°C Mean Heart Rate (# 23.67 23.89 24.33 27 35.89 37.78 beats/10 sec) What is the Q1o value for heart rate (# of beats/10 seconds) for the temperature interval of 25°C - 35°C? Round your answer to two decimal places.

The Bay of Fundy in Nova Scotia, Canada is reported to have the largest tides in the world with high tide and low tide occurring two times per day. The tides can measure ft in height. At the Hopewell Rocks at Hopewell Cape, over approximately 50.0 on a specific day height increase was recorded as a rate of 6.08 feet per hour. What is the rate in meters per second ?

2 W S Type your answer to the following: Consider the steps the student took in the following scenario. Then describe anything the student did wrong and how it would have affected the student results (too high, low, or unchanged) and why. X A student forgot to weigh the filter paper prior to filtering the salt from the sand. To make up for this, the student weighed a different filter paper from the box and used that mass in the calculations.

Density of Zinc: Consider the data and results from the density of zinc determination. Now focus on the average absolute error associated with the calculated average density of zinc. Which measurement contributes the most relative error to this value? Given that measurement and its associated absolute error, is the calculated average absolute error reasonable and why? What aspect of the experiment limited the measurements the most?

if you could please help! i submitted this previously and was told that it looks incomplete. the questions are complete and there is no additional information to upload with the questions. again there are 6 questions and i have done a majority of them. i really just need help with question 2 and 3, however, if you could look at my answers for the questions i did and tell me if they are correct i will gladly rate you! thank you so much. I apologize if it is small, i made the font smaller to fit everything on one picture

2. The following eight structures are all isomers of C6H14O. Each structure corresponds to one of the predicted ¹H NMR spectra pictured on the next two pages of this document. The integral values for each peak are next to that peak. Indicate which structure matches each spectrum by drawing the structures in the boxes along the right side of the pages. Use the letter codes provided to label the chemically equivalent hydrogens on the structures. One example is provided.
