Which statement best predicts the activity of an enzyme-catalyzed reaction as the concentration of substrate in a sealed flask decreases? a. the rate of the reaction will increase. b. the rate of the reaction may increase or decrease. c. the rate of the reaction will decrease. d. the rate of the reaction will not change.

The correct option is C.
In a chemical reaction, enzymes usually work on the substrates and speed up their rates, so that the reaction will occur faster. When the concentration of the substrate is high, the enzyme will work optimally, but when the substrate concentration decrease, the enzyme activity too will decrease, because it has less substrate to work on.

Because the earth is not round ,but it may seem round when viewed from ,our planet but true some points earth is not round was an oblate spheroid -a square that it squashed as globe however is not even a perfect oblate spheroid.in fact isaac newton's first proposed that earth was not perfectly round but it was an oblate spheroid instead.that mean a square that is squashed as its poles and swollen at the
