By considering the molecules of an insulator, explain how an insulator can be overall neutral but carry a surface charge when polarized.

A) Inside the insulator, the oppositely charged ends of the molecules cancel each other.

B) Inside the insulator, the oppositely charged ends of the molecules do not cancel each other.

C) The electron distribution in all the molecules shifts in every possible direction, leaving an excess of positive charge on the opposite end of each molecule

D) The electron distribution in all the molecules shifts in a given direction, leaving an excess of negative charge on the opposite end of each molecule

In the video, the students discussed with the professor how objects can become charged through contact interactions at the microscopic level. Which of the following could possibly happen when two neutral objects are rubbed together? There may be more than one possibility. (Select all that apply.) a) There might not be any changes to the chemical bonds between atoms, and the two objects remain neutral after contact. b) Rubbing imparts energy to the two objects, allowing them to create excess...

1 In the absence of oxygen, cells consume glucose at a high, steady rate. When oxygen is added, glucose consumption drops precipitously and is then maintained at the lower rate. Why is glucose consumed at a high rate in the absence of oxygen and at a low rate in its presence? 2 In the following diagram showing the distribution of thermal energy in a population of substrate molecules, the energy thresholds indicated by numbers represent ...

1) 2 point charges are separated by a distance of 8 cm. The left charge is 48 mC and the right charge is -16mC. Using a full sheet of paper: draw the 2 charges separated by 8cm, centered in the sheet. (if you are missing a ruler estimate 8cm as ⅓ a paper sheet length).

Lab 9 – Molecular Biology In this lab, you will prepare an agarose gel and use gel electrophoresis to compare the size of 2 dye molecules Methyl orange and Ponceau G. You will also analyze an “unknown” sample that contains a mixture of two dyes. Dye molecules with lower molecular weight or greater electrical charge will migrate faster through the gel, than dye molecules with greater molecular weights or lesser electrical charge.
