</span>Fluency
disorder is a communication disorder that involves discontinuous flow and
timing of speech. It is mostly seen in children who are learning to speak. Physical
tension, negative reactions, and avoiding of speaking situations work together
with this disorder. Individuals with this disorder display repetition of words,
sound extensions and long pauses when speaking. For the question given above, a
12-year-old student who says "i-i-i-i want i-i-i-ice c-c-c-cream" is
exhibiting fluency disorder.</span>
The answer is;
a. add electric current.
b. add buffer solution
The process of gel electrophoresis taps on the property of net charges of molecules to ensure that they travel up the gel. Additionally, the buffer acts as the mobile phase for the molecules and also give molecules net charge as they travel through the gel. It is until the molecules reaches an isoelectric point,where the molecule has zero net charge, that they stops moving through the gel. This is how bands are formed.
