The answer is False.

Explanation: The statement that "no drug can penetrate this barrier" is incorrect. While the blood-brain barrier (BBB) is indeed a protective barrier that restricts the passage of many substances from the bloodstream into the brain, it is not completely impermeable. Certain drugs and molecules can cross the BBB, especially those that are lipid-soluble or have specific transport mechanisms. For example, some medications for neurological conditions, such as certain antidepressants and antiepileptic drugs, are designed to penetrate the BBB to exert their effects on the brain. Additionally, researchers are continually developing new methods to enhance drug delivery across the BBB for treating various brain disorders.

The table below shows the results of a survey that asked 1056 adults from a certain country if they favored or opposed a tax to fund education. A person is selected at random. Complete parts (a) through (c). - Support Oppose Unsure Total Males 151 323 11 485 Females 245 302 24 571 Total 396 625 35 1056 (a) Find the probability that the person opposed the tax or is female. P (opposed the tax or is female) = .847 (Round to the nearest thousandth as needed.) (b) Find the probability that the person supports the tax or is male. P (supports the tax or is male) = .691 (Round to the nearest thousandth as needed.) (c) Find the probability that the person is not unsure or is female. P (is not unsure or is female) = (Round to the nearest thousandth as needed.)
