Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge. Electrophoresis involves running a current through a gel containing the molecules of interest.

Answer:
Pollination is the transfer of pollen from a male part of a plant to a female part of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind.
The statements which are true about half-life are given below:
- A radioactive element's half-life stays the same when its temperature changes.
- A radioactive element's half-life stays the same when the pressure upon it changes.
Thus, the correct options are B and F.
<h3>What is Half-life?</h3>
The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.
The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.
Therefore, it is well described above.
