Answer:
convention currents in the earth's mantle
Explanation:
the convention currents move the plates and that is how plates move
The scientists who provided this hypothesis had an idea that the species evolved in order to accommodate their needs on certain islands. For instance, an example is beak size of certain birds which Darwin thought that this was to eat certain foods.
The answer is C.)sending them on the shuttle to be suspended in space. This is the answer because after the nuclear fuel rods come out of the reactor, they go into a deep pool to cool off. Then they are then stored in concrete and lead-lined casks for dry storage, until, ultimately, the US government builds a deep underground storage facility to house them permanently. They are never sent on the shuttle to be suspended in space<span>. It would be too costly and too dangerous.</span>
Answer:
The rate at which an enzyme catalyses a particular reaction is calculated by the amount of substrate being used up. The concept of a chemical reaction is that the substrate is converted into product with the help of an enzyme.
Rate of reaction= Amount of substrate utilized or product formed/ Time taken
Explanation:
Temperature is an important factor in the deciding of a rate of reaction. The velocity of an enzyme <u>increases with an increase in temperature</u> until and optimum temperature is achieved. After that, the velocity of an enzyme starts <em>decreasing</em> since the enzyme starts to get denatured.
Enzymes work best at a <em>specific pH</em>. If there are changes in pH, the active site of an enzyme gets modified and the rate of reaction decreases. Certain enzymes like pepsin which is in our stomach works at an acidic pH of 2.0.
