Explanation:
They are opposites because they are the same chemical reaction but reversed. Cellular respiration takes glucose (from nutrient/food) and oxygen (from atmosphere) in order to make CO2 (think about exhaling) and H20 (water).
Hello!
Chemical reactions require energy to begin. The reactants must collide with enough energy for bonds to change. This energy is known as activation energy - the difference in energy between that of the reactants and the amount needed for the reaction to occur.
Catalysts lower the activation energy needed for a chemical reaction to occur, therefore also increasing the rate of a reaction. Enzymes are proteins which act as catalysts within cells.
Therefore, enzymes cause the activation energy to lower.
Hope this helps!
Answer: 5.138 × 106
Explanation:
1.Move the decimal place to the left to create a new number from 1 up to 10.
2. Determine the exponent, which is the number of times you moved the decimal.
3. Put the number in the correct form for scientific notation (N*10^a)
Where N equals between 1 and 10, but not 10 itself, and a is an integer (positive or negative number).
Answer:
is defined as the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.
