While testing amylase activity, John uses a buffer of pH 6 and substrate starch. He incubates them at 104ºF (40ºC). All the tubes show glucose formation, except one, which had no starch solution. Why did this happen? A. The optimum pH for the enzyme amylase is not pH 6. B. The optimum temperature for the enzyme amylase is not 104°F (40°C) C. The substrate for amylase, starch, is not present.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

answer: #1 ads up by 8 and i don't know #2

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
