A subquery is a query(expressed as a SELECT statement) that is located inside another query. The first SQL statement is known as the outer query, the second is known as the inner query or subquery. The inner query or subquery is normally executed first. the output of the inner query is used as the input for the outer query. A subquery is normally expressed inside parenthesis and can return zero, one or more rows and each row can have one or more columns.
Gel electrophoresis can't be used for uncharged or neutral molecules, because the movement of the charged particles only make this happen

This is because of greenhouse gases and polution.
There are different materials of raw water, but also the raw water comes from ponds,rivers, and oceans but they might be good sometimes, and gas not been treated and has bacteria or mold buy that is not good.
The change in internal energy of this gas sample is equal to: c. 715 J.
<u>Given the following data:</u>
- Quantity of heat = 874 J.
<h3>What is the First Law of Thermodynamics?</h3>
Mathematically, the the First Law of Thermodynamics is given by this formula:

Where;
is the change in internal energy.
- Q is the quantity of heat.
Substituting the parameters into the formula, we have;

Change in internal energy (ΔH) = 715 Joules.
