Answer: size</h2>
Gel electrophoresis is called to the technique used by scientists for analytical purposes, in life sciences laboratories to separate macromolecules (DNA, RNA, and proteins from various sources).
The process consists of separating the molecules according to their <u>size</u> and <u>electric charge</u>. This is done with a gel (a gelatinous substance extracted from seaweed, called <em>agarose</em>) of controllable porosity placed in an ionic buffer environment. This is how the gel acts as a molecular sieve that separates larger molecules from the smaller ones, because each molecule has different size and charge and will move through the gel at different speeds.
That is, the smaller molecules move more quickly through the gel while the larger ones are left behind.
Answer:

Explanation:
In microwave, there are waves called "microwaves" as per the name. So, The heating of food is done with the help of waves. Radiation is "the transfer of heat through waves". That is why the process of heating food in a microwave is "Radiation".
This is called Conduction.
Answer: 0.064 m/s²
Explanation:
Initial velocity = 22m/s
Final velocity = 44m/s
Time taken = 345 seconds
Acceleration = (Final velocity - Initial velocity) / Time taken
= (44 - 22) / 345
= 22/345
= 0.0637681
= 0.064 m/s²
Therefore, the acceleration is 0.064 m/s².
