Answer:

\boxed{\text{3.4 g}}

Explanation:

Step 1. Calculate the moles of C₁₂H₂₂O₁₁

\text{n = 0.100 L} \times \dfrac{\text{1.0 mol}}{\text{1 L}}=\text{0.100 mol}

Step 2. Calculate the mass of C₁₂H₂₂O₁₁

\text{m = 0.100 mol} \times \dfrac{\text{342.30 g}}{\text{1 mol}} = \text{3.4 g}\\\\\text{The mass of sucrose needed is }\boxed{\textbf{3.4 g}}

Assume that instead of Taq polymerase, another polymerase, one that is very heat-sensitive, was used in a PCR. What differences
frez [133]

Answer:

Taq polymerase is a thermostable which states that it can even work at higher temperature. The main function of using this enzyme is that it is used to amplify the DNA which will help in producing ample amount of DNA sample.

The enzyme activity is temperature dependent. The denaturation and annealing steps of the PCR occurs at very high temperature.

Any other enzyme used at such an high temperature would have decreased the enzyme activity and the procedure would not be completed.

consider a 1000-ml graduated cylinder with marks every 100 ml. a student records the volume of liquid in the cylinder as 750 ml.
kap26 [50]

Answer:

Yes, given statement is true.

Explanation:

Given that a cylinder of 1000 ml is marked at every 100 ml.

During the test, the student can easily check the volume of liquid so the student's guess is 750 ml true.  

With this measurement, we can estimate that 1/10th of 100 ml can be measured.  

So, given statement is correct.
