Answer:
Activation energy.
Explanation:
Activation energy may be defined as the minimum amount of energy required for the conversion of the reactant to the product. The reaction must have least activation energy to convert the reactant into product.
The reactant must pass this activation energy to convert them into the product. Catalysts are used in the reaction to lowers this activation energy and increases the rate of the chemical energy. The activation energy acts as the thermodynamic barrier that hinders the conversion of substrate into product.
Thus, the correct answer is option (A).
Redi and Pasteur were both trying to disprove the hypothesis of spontaneous generation that stated that a living organism can emerge from inorganic matter or dead flesh. Therefore, it was essential for their research to completely seal their vials and prevent contamination with living things and spores from the environment in order to prove that living things do not emerge spontaneously.
Answer:
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently).
Answer:
The structure of ATP will need to be used.
Explanation:
Adenosine triphosphate or ATP is an energy rich compound which undergo hydrolysis in presence of water to generate free energy.
When a molecule is moving against its concentration gradient it requires the input of energy which is generally supplied by the hydrolysis of ATP molecules.
For example Na+K+ATPase uses the energy derived from ATP hydrolysis to transport Na+ inside the cell and K+ outside the cell.
The tick uses the dog for two reasons. 1.It uses the dog as a source of food. 2.It also uses a dog for means of transportation from one place too another. And so the dog gains nothing
