If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.
The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.
Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.
15 x 1/500
= 0.03 cm

Free electrons seem to travel via the conductors with a certain degree of friction, or opposition to the motion. This opposition to the motion is more precisely known as resistance.
The amount of the current in a circuit relies on the concentration of voltage accessible to encourage the electrons, and also the amount of resistance in the circuit to oppose the flow of electron. Resistance to the flow of electrons in a conductor causes a loss of energy in the form of heat.

When a single celled paramedic is placed in a hypotonic solution, the cell swells and then bursts.
<h3><u>
Explanation:</u></h3>
Hypotonic solutions are the solutions that contain more water than present in a cell. Hence, when an animal cell is placed in a hypotonic solution, the cell will undergo osmosis. Osmosis is the movement of any form of solvent through a plasma membrane to a higher concentration from a lower concentration until the the external concentration matches the inner one.
To put it in simple words, when a single animal cell is places in a solution which has more water than other solutes, the water will invade the cell until it can accumulate the amount that equalizes the inner and external concentration. The cell will begin to swell up until there is no more space and finally, it will burst. For example, when you put water on a cloth that has blood stain on it, the cells will burst and make the stain worse than before.
It moves by active transport.hope this helps!
