A researcher conducted a study to determine the effects of insulin concentration on the adipogenesis of fibroblast cells. The absorbance of light by the dye OPD is directly proportional to the number of fat produced.  Interpret the results provided in the graph below and write a paragraph as if it were the Interpretation section of the lab report. Make sure to include the following information:   1. What is the effect of the different insulin concentrations in the fat produced by the adipocytes? 2. Provide a possible explanation for the results observed when insulin concentration increased from 1 to 4 ug/mL.     

The following are metal pairs representing electrodes in theoretical voltaic cells. Which pair is incorrectly labeled?        (1) Ag, oxidized/ Cu, reduced                    (2) Ag, oxidized/ Au, reduced (3) Ni, reduced/ Al, oxidized                        (4) Cu, reduced/ Pb, oxidized         (5) Na, oxidized/ Mg, reduced

Consider the following reaction at 25°C and select the false statement from below. Mg(s) + Fe2+ (aq) ⇋  Mg2+ (aq) + Fe(s)          (1)  E° > 0          (2)  ΔG° < 0            (3)  K > 1     (4)  Mg is a stronger reducing agent than Fe          (5) Mg2+ is a stronger oxidizing agent than Fe2+

True or False:   Microglia conduct and transmit information to other cells.

Select the correct answer from the dropdown menu:   [migrat1] cell migration is characterized by a restructuring of the extracellular matrix, while in [migrat2] cell migration, the cells change the shape of their plasma membrane.

Name one difference between white adipose tissue (WAT) and brown adipose tissue (BAT).

BONUS QUESTION 1:   To study the excess uptake of LDL-cholesterol, a researcher is treating THP-1 human macrophage cells with Imipramine (inhibitor of macropinocytosis), and Genistein (inhibitor of caveolae-mediated micropinocytosis). He is then measuring the levels of LDL-cholesterol taken in by the cells receiving the drugs versus the control.    Based on this information, propose a research question.
