If you flip a penny 99 times and each time it came up heads then the chance of the penny coming up heads is ___
Helga [31]
The chances of heads as a result when flipping a penny will always be 50%. Although heads came up 99 times in a row, the events that occurred before will not affect the probability of the current event in terms of a coin flip.

There are 1 out of 2 chances of it occurring or 1/2. Divide that and multiply it by 100% to get the probability in percent. So the answer will be 50%.

The answer is B.

If polar is positive and non-polar is negative then why can’t a polar molecule pass through the non-polar phospholipid membrane
Ierofanga [76]

Answer:

Because of the chemical and structural nature of the phospholipid lipid by layer the lipid soluble molecule can just pass the lipid membrane and some small molecules can also pass freely.

Explanation:

as we know that the homeostasis is an important process for a  living cell to maintain it self so for the the exchange of materials between the external and internal environment is must so for that it exchange material with the outside environment of the cell.as the cell membrane is semipermeable(mean allow some molecule to pass(lipid soluble) and not others(lipid non soluble) to pass through the membrane.the cell membrane is selectively permeable due to its nature and chemical composition the chemical composition is lipid and  phosphate and glycerol(head) with fatty acid that may b saturated or unsaturated(tail).so finally all those molecule which are polar can not pass through the membrane and  non polar can pass the membrane.The size of the molecule is also a factor on which the permeability depends.
