Why are capillaries and not arteries or veins found in alveoli, nephrons, and villi?

Vessel walls must be thin to allow ease of transfer of molecules to these tissues. ... Axons must have structures that make and secrete molecules, and muscle cells must have receptors that recognize these molecules.

Explanation:

a) The odds that such a taxpayer will be audited is 4%.

b) The odds against such a taxpayer being audited is 96%.

Step-by-step explanation:

a) Data and Calculations:

The probability of an IRS audit = 3.8% for U.S. taxpayers who file form 1040 and earned $100,000.

This is the same as the odds that such a taxpayer will be audited.  Odds is the likelihood or chance that an event will take place.

b) The probability of not being audited is 100 - 3.8% = 96.2%

The odd against being audited is the likelihood or chance that an event will not take place.
