Based on the enzyme performance under optimal conditions and data from graph A, which of the following best predicts the metalloproteinase activity at 60° C at a substrate concentration of 4.0? A) Metalloproteinase activity at 60°C will be half the activity of the enzyme at 37°C
B) Metalloproteinase activity at 60°C will be double the activity of the enzyme at 37°C
C)Metalloproteinase activity at 60°C will be the same as the activity of the enzyme at 37°C
D) Metalloproteinase activity at 60° C will be 10 times lower than the activity of the enzyme at 37°C

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.

condenser is used to focus in the light microscope.

barometer is an instrument used to measure the atmosphere's pressure. the high air pressure relative to average levels is associated with calm and sunny weather. on the other hand, low pressure is associated with bad weather, high winds, and rain.
