Answer:
D. Create a cell reference in a formula by typing in the cell name or clicking the cell.
Further Explanation:
To create a cell reference in a formula the following procedure is used:
First, click on the cell where you want to add formula.
After that, in the formula bar assign the equal (=) sign.
Now, you have two options to reference one or more cells. Select a cell or range of cells that you want to reference. You can color code the cell references and borders to make it easier to work with it. Here, you can expand the cell selection or corner of the border.
Again, now define the name by typing in the cell and press F3 key to select the paste name box.
Finally, create a reference in any formula by pressing Ctrl+Shift+Enter.
Having to compare results on experiments or lab tests to each other.

Explanation:
Buffer solutions are the solutions which can resist the change in the pH up to some extent. They are the solutions of either weak acid and conjugate base of it or weak base and conjugate acid of it.
The pH of a buffer solution can be measured by the equation known as Henderson–Hasselbalch equation.
pH=pKa+log[base]/[acid]
A good buffer that buffer which has its acid's pKa within one pH unit of desired experimental conditions.
Thus, desired pH = 5.3
Preferable pKa = 4.3 - 6.3
<u>Answer - B. 4.75</u>
Answer: B) Shape is a base class, and circle and square are derived classes of Shape.
Explanation:
Shape is a base class because circle and squares are the shapes so these are the derived class of the shape, which is inherited by the shape like circle and square. As, the base class (shape) is the class which are derived from the other classes like circle and square and it facilitates other class which can simplified the code re-usability that is inherited from the base class. Base class is also known as parent class and the super class.
