10. Wei saw a special type of plastic that would melt and become a liquid when it was placed in the sun, but it would not melt w

hen placed under a desk lamp. Why does light from the sun melt the plastic when light from the desk lamp does not? Because the plastic can take in energy from the light from the sun but not from the light from the lamp. b Because light from the sun carries heat molecules, and light from the desk lamp does not. Because light from the sun pulls energy out of the plastic, and light from the desk lamp does not. Because the sun gives off a type of light that carries erlergy, and light from the desk lamp does not.​

At the isoelectric ph of an amino acid which has two pka values the net charge is ________.
Ierofanga [76]

The isoelectric pH has been defined as the electrically neutral molecule. "At the isoelectric pH of an amino acid that has two pKa values the net charge is <u>0</u>." Thus, option C is correct.

<h3>What is isoelectric pH?</h3>

The isoelectric pH has been defined as the potential of the hydrogen at which the molecule does not carry a net charge and is said to be electrically neutral. The amino acids at isoelectric pH do not carry a charge.

If there are two pKa values of the amino acid then the amino acid has zero charges as the amino acids are always neutral at the isoelectric point.

Therefore, in option C. the net charge is <u>zero</u>.
