Textbook Question
Chapter 13, Problem 13.8PS
Stressed Out. It is now possible, via nanoengineering, to attach magnetic beads to the surface of large cells. Using the beads, you apply force to measure how mechanically stiff the cells are. What effect would you predict acrylamide treatment would have on the mechanical rigidity of a keratinocyte (skin cell)? Explain your answer.

- Please help. An explanation will be very helpful. Thank youarrow_forwardFill in the blanks. Biological molecules in the cell are (colored/colorless). Most stains used are basic stains and have a (positive/negative) charge so they bind to the (positively/negatively) charged molecules (DNA and proteins) in the cell.arrow_forwardPhysical therapy and low level laser therapy. How LLLT can be used in this practice ? Has it been used in this practice? Would it be beneficial?arrow_forward
- Hello, good day. I have a problem answering this question, and I need your help. Hoping for a response, and thank you so much. Instruction: The answer must be in a minimum of 2 paragraphs, and each paragraph must have a minimum of 4 sentences. Question: Research have stated that there are factors that could affect the efficacy and duration of mosquito repellants on our skins. State at least 3 factors that could decrease or influence the efficacies of topical mosquito repellants.arrow_forwardTrue or false .Very powerful X-rays used in crystallography are generated in a very large facilities called synchrotron .A western blot allows detection of proteins after SDS-PAGE with higher sensitivit .Keratin and collagen adopt helical structures whereas silk fibroin adopts beta sheet structures .arrow_forwardPlease answer.

- Help Please. Option 3 is not correct for this.arrow_forwardFill in the Blanks. What are the correct answers?arrow_forwardPlease help me with this question. More than one answer may be correct. THe graph relating to the information is included below. The above figures show the rate of actin polymerization in the presence of various concentration of profilin (Pfn). In the top figure, flourescence intensity is a measure of total actin that has been polymerized, and this is plotted versus time in seconds. The shade of blue of the lines in the top figure correspond to the shaded blue bars representing various concentrations of profilin in the lower figure. The lower graph shows the initial rates of polymerization of actin plotted again concentration. Which of the following is true: Question 21 options: profilin in a molecular motor profilin is a promoter of actin polymerization profilin replaced G-actin in an F-actin strand and breaks the filament profilin is an inhibitor of actin polymerization profilin binds to G-actin, preventing it from polymerizingarrow_forward
