Catalase is an enzyme that protects human cells from damage by helping convert the toxin hydrogen peroxide (H2O2) into water (H2O) and oxygen
(O2). A student is investigating how different pH values and different
temperatures affect catalase activity. The table below shows the student's
data. Which of the following test tubes has the physical conditions most
similar to human cells?

a. by using fur or clothes to trap heat energy near the body

d we did this already

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
