Textbook Question
Chapter 7.2, Problem 3CC
MAKE CONNECTIONS Ø Aquaporins exclude passage of hydronium ions (H3O+), but some aquaporins allow passage of glycerol, a three-carbon alcohol (see Figure 5.9), as well as H2O. Since H3O+ is closer in size to water than glycerol is, yet cannot pass through, what might be the basis of this selectivity?

Chemistry
Q4 1mL of the stock solution acetaminophen (1mg/mL) is used for the estimation of PC using n-octanol. After extraction, 0.1mL of the extracted solution was added to 0.9mL of water and 100uL of this solution was loaded in 96 well plate to the absorbance at 260nm. If the observed absorbance of the extraction phase is 0.2 using the following standard curve equation, Calculate the concentration of acetaminophen in aqueous Phase.
Note: If you need the standard curve equation, please make It up because I want to understand the concept.
Please explain in steps like how to approach the problem
VOLUTION CONNECTION This chapter explains how theemergent properties of water contribute to the suitabilityof the environment for life. Until fairly recently, scientistsassumed that other physical requirements for life includeda moderate range of temperature, pH, atmospheric pressure,and salinity, as well as low levels of toxic chemicals. Thatview has changed with the discovery of organisms knownas extremophiles, which have been found flourishing inhot, acidic sulfur springs, around hydrothermal ventsdeep in the ocean, and in soils with high levels of toxicmetals. Why would astrobiologists be interested in studyingextremophiles? What does the existence of life in suchextreme environments say about the possibility of life onother planets?
WHAT IF? How would the membrane lipid composition of a native grass found in very warm soil aroundhot springs compare with that of a native grass foundin cooler soil? Explain.
