Instructions: Read the question(s) carefully and provide an in-depth answer. The purpose of these homework assignments is to think about the topics and concepts we discussed more deeply. We have looked at sphingosine as a membrane lipid that is important as a glyco-conjugate and is the membrane anchoring molecule for the carbohydrates that determine O,A,B, and AB blood types. It has also been implicated as an important signaling molecule when phosphorylated to yield sphingosine-1-phosphate (head group is phosphate), that is involved in diseases such as cancer. Draw the chemical structure of sphingosine-1-phosphate and using chemical principles rationalize/explain why it would be functional as a signaling molecule (must travel through blood) and not as a component of the lipid bilayer. (Remember what determines lipid bilayer formation and principles from the water chapter)

The restaurant owner would like to compare the number of beef and vegetarian meals ordered. The number of beef and vegetarian meals ordered on 10 randomly selected days was entered into Microsoft Excel and the mean and standard deviation was calculated for each sample. The information is shown below. A B C D E F G H J K 1 Vegetarian 49 53 61 57 50 48 66 61 54 56 2 Beef 37 35 30 41 29 45 31 37 40 33 3 4 Vegetarian: 5 x = 55,5 6 S= 5,87 Beef: x = 35,8 S = 5,20 Which of the following statements is true? a) The CV for the vegetarian data is 62% and the CV for the beef data is 75.5% meaning that the beef data is more variable than the vegetarian data. 0 b) The range for the vegetarian data is larger than that of the beef data meaning that the vegetarian data is less variable. c) The variability of the two data sets cannot be calculated because beef is a meat product and vegetarian meals contain no meat. d) The CV for the vegetarian data is 10.6% and the CV for the beef data is 14.5% meaning that the beef data is about one-and-a-half times more variable than the vegetarian data.

Exercises 36-39: Suppose that $\mathcal{L}\{f_1(t)\} = F_1(s)$ and $\mathcal{L}\{f_2(t)\} = F_2(s)$, $s > a$. Use the fact that $\mathcal{L}^{-1}\{c_1F_1(s) + c_2F_2(s)\} = c_1\mathcal{L}^{-1}\{F_1(s)\} + c_2\mathcal{L}^{-1}\{F_2(s)\}$, $a < s$ to determine the inverse Laplace transform of the given function. Refer to the examples in this section and equation (11) in Exercise 15. 37. $F(s) = \frac{2}{s^2} + \frac{1}{s+1}$

According to our text (chapter 6), scientists have discovered (based on equipment like the fMRI) that "Babies are thinking long before they talk." Should these findings have an impact on our behavior with regard to our own personal behavior, interactions with others or our interaction with babies? How would you go about explaining to parents, family members and care givers the importance of these findings? Can you name a few examples of behaviors that have an impact on the development of babies that caregivers may not automatically recognize? "Hint: In our text there have been several examples of behaviors on the part of caregivers that can impact child development."
