Your medical bill is 2345 your health insurance covers 70% after a 120 deductible what amount of the bill will you pay
astra-53 [7]
The solution for the problem is:
Since there is $120 deductible, you get to pay…$2345 - $120 = $2225.
But since the insurance covers 70%, so you will only pay the 30%, so it is:30% x 2255 =30/10 * 2225 == $667.50 would be the amount you will be paying.

What do you think selectively permeable means?
enot [183]

Answer:

B. The membrane lets certain substances move across it freely, while others must move through a “gate”.

Explanation:

Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. For example, water, ions, glucose and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity. Similarly, signaling molecules may need to enter the cell and proteins may need to be released into the extracellular matrix. The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing and rate of movement of these molecules.
