The option (d) is correct DNA polymerase enzyme are nucleotides the substrate.
We refer to a substance as a substrate when another substance is added to it. It is defined differently in several sciences. It is a molecule or substance that, when exposed to a catalyst, enzyme, or inhibitor, causes a chemical reaction. In the field of material sciences, the term "substrate" is widely used to describe the base material on which various processing operations are carried out with predetermined reaction parameters to produce additional layers and films, such as coatings. As a result, there are numerous definitions available in the literature, depending on the substrate's applications and area of study. A molecule with which an enzyme interacts is known as a substrate. A substrate is put into the active site of the enzyme, which is where weak bonds between two molecules might form. The substrate reacts under the pressure of the enzyme, forming an enzyme substrate complex that is the product of the intended reaction. The bonds that form between the substrate and the enzyme are what induce the conformational shift, or shape change, in the enzyme.

Answer:
The limiting reactant is H₂
Explanation:
The reaction of hydrogen (H₂) and carbon monoxide (CO) to produce methanol (CH₃OH) is the following:
2H₂(g) + CO(g) → CH₃OH(g)
From the balanced chemical equation, we can see that 1 mol of CO reacts wIth 2 moles of H₂. So, the stoichiometric ratio is:
2 mol H₂/1 mol CO = 2.0
We have 500 mol of CO and 750 mol of H₂, so we calculate the ratio to establish a comparison:
750 mol H₂/500 mol CO = 1.5
Since 2.0 > 1.5, we have fewer moles of H₂ than are needed to completely react with 500 moles of CO. In fact, we need 1000 moles of H₂ and we have 750 moles. So, the limiting reactant is H₂.
Answer:
The power of the kitchen blender is <span>250<span>Js</span></span>
Explanation:
Let's use the following formula:
<span>P=<span>WT</span></span>
<span>P stands for power and it is measured in Watts (W) or (J/s)<span>W stands for work and it is measured in Joules (J)</span>T stands for time and it is measured in seconds (s)</span>
We know the work that was done as well as the time, both of which have the correct units. All we do now is plug in the given values for W and T and solve for P like this:
<span>P=<span><span>3750J</span><span>15s</span></span></span>
<span>P=250<span><span>Js</span></span></span>
The equilibrium expression for the reaction; C(s) + O₂(g) ------->CO₂(g) is [CO2]/[C] [O2] option C.
<h3>What is the equilibrium expression?</h3>
The equilibrium expression shows how much of the reactants are converted into products. If the equilibrium constant is large and positive, most of the reactants have been converted into products.
Thus, the equilibrium expression for the reaction; C(s) + O₂(g) ------->CO₂(g) is [CO2]/[C] [O2] option C.
