You have labeled your cells for two markers CD45 (conjugated to APC chromophore) and CD8 (conjugated to Pacific Blue chromophore). After staining your controls and sample, you analyze them via flow cytometry and obtain the following results. Which pair of histograms belongs to which sample (C1: unstained control, C2: CD45-only stained cells, C3: CD8-only stained cells and S1: CD45 + CD8 stained cells).                                                   #1 [answer1] ____________________________________________________________________                                                  #2 [answer2] ____________________________________________________________________                                                  #3 [answer3] ______________________________________________________________________                                                  #4 [answer4] ___________________________________________________________________

The end feel for wrist extension may be firm due to:

Your patient presents with limited wrist radial deviation ROM secondary to muscular tightness.  The PT plan of care indicates you are to perform stretches to the tight musculature.  Which muscle(s) will you target? Select all that apply.

SCENARIO A (will be used for multiple questions) You patient Tom is recovering from an UE injury. Upon goniometric assessment, you note the following active values: Elbow flexion = 125 degrees Elbow extension = 2 degrees Forearm pronation = 10 degrees Forearm supination = 12 degrees Wrist flexion = 35 degrees Wrist extension = 45 degrees One of Tom’s goals is to return to full restaurant serving duty which requires that he carry trays loaded with food and beverages, with his palm & tray at shoulder height (as pictured below). Assuming his limitations are due to muscular tightness, which of the following muscles should receive the greatest emphasis during stretching exercises? Select all that apply. waiter with tray.png

The representative molecule QX4 is being studied by researchers and the information about elements Q and X is below. How many grams of QX4 would contain 2.61 x 1024 molecules of QX4 (use the information provided)? 

Given A has 5 valence electrons and X has 7 valence electrons, which is the X-A-X bond angle in AX3? 

Consider the following molecules below and determine which of the following statements are true or false.  BrF3          BeCl2            SiF4        KrF2           BH3  Two of the molecules have an incomplete octet [1] Two of the molecules have an expanded octet [2] Two of the molecules have an odd number of electrons  [3]

Given A has 5 valence electrons and X has 7 valence electrons, which is the molecular shape/geometry of AX3?
