Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of
VMariaS [17]

Answer: positive sodium ions

Explanation:

This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.

The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.

How many calories are in an average trick-or-treaters halloween stash?
Vera_Pavlovna [14]

The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.

Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.

Considering this, in a Halloween stash the calories depend on two factors:

  • The types of candies or products
  • The units of each one

Let's suppose there are 5 units of each of the following candies:

  • Chocolate bars
  • Taffies
  • Lollypops
  • Candy corn

Let's now calculate the calories

  • Chocolate bars = 220 calories x 5 units =  1,100 calories
  • Taffies = 20 calories x 5 units = 100 calories
  • Lollypops = 83 calories x 5 units = 415 calories
  • Candy corn = 7 calories x 5 = 35 calories

Add all the previous results:

1,100 + 100 + 415 + 35 = 1,650 calories in total
