Difference of two squares
it always results in a^2-b^2
All of the following are involved in Type 2 hypersensitivity, except D. IgE
<h3>What is Type 2 hypersensitivity?</h3>
This refers to the type of reaction where the body has an immune reaction to antibodies (IgG or IgM) that are directed at certain areas of the body that leading to functional loss, or tissue damage
Hence, we can see that from the complete question, there are different answer choices that show the different antibodies that are involved in the immuno-reaction and the one that is NOT involved in the list of options is IgE.

Ionic charge increases from left to right in periodic table which results in a decrease in ionic radius.
Ionic charge is the electrical charge of an ion formed when when an atom gains or losses electron.
Metals form ionic charge (cation) by the loss of electron while non-metal form ionic charge (anion) by the gain of electron.
- This ionic charge increases across the group and consequently, results in a decrease of ionic radius.
- When a positive ion (cation) transfers electron to the negative ion (anion) an Ionic bond will be formed.
<u>For example</u>;
- ionic charge of group 1 elements = +1
- ionic charge of group 2 elements = + 2
- ionic charge of group 3 elements = + 3
- ionic charge of group 4 elements (carbon group) = -4 or +4, (<em>they don't usually form ions</em>)
- ionic charge of group 5 elements = -5
- ionic charge of group 6 elements = -6
- ionic charge of group 7 elements = -7
Thus, we can conclude that ionic charge increases from left to right in periodic table which results in a decrease in ionic radius.

Data analysts use the <u>CLEAR FORMAT</u><u> </u>tool to create a clean and consistent visual appearance for their spreadsheets.
<h3>Database </h3>
A database is an organized collection of data stored in a general or personal computer A database can be created with spreadsheets in order to produce a clean and consistent data for the purpose of study and analysis.
Every database has it own formatting and this leads to data inconsistency as well. To avoid inconsistency of data, Data is cleaned by analysts with the use of the tool clear format.
Hence we can conclude that Data analysts use the <u>clear format </u>tool to create a clean and consistent visual appearance for their spreadsheets.
