Question:

How do I change a number to a percent in Excel?

Heather S.
Answer:

There are a couple of ways to do this. The easiest way is to highlight the cell or column and then under the Home Tab, under Number, click on %. You can also highlight and right click on to open up the menu. Then click on Format Cells, then under Number, click on Percentage. You can then adjust the number of decimal spaces and click on OK.

Question:

What is the difference between a covalent bond and an ionic bond?

Heather S.
Answer:

With a covalent bond, valence electrons are shared between different atoms forming a strong bond. In an ionic bond, valence electrons are either gained or lost to another atom giving each atom a positive or negative charge, creating ions. The ions are attracted to each other due to those opposite charges creating an weaker bond.

Question:

You started out as a single cell called a zygote. Explain how you developed into the complex organism that you are with many different types of cells with different functions.

Heather S.
Answer:

The zygote divides my mitosis repeatedly to form exact copies of the original cell with the same DNA. Those cells then go through the process of cell differentiation to form the different types of cells in your body. Cell differentiation expresses, or turns on, the genes needed to form a specialized cell, such as a skin cell, while turning off genes not needed.
