Answer:
Large molecules do not pass through the BBB easily. Low lipid (fat) soluble molecules do not penetrate into the brain. However, lipid soluble molecules, such as barbituate drugs, rapidly cross through into the brain. Molecules that have a high electrical charge are slowed.

Benchmark Poll voter survey carried out immediately after polling stations left. The elections are a example.
Random Sample is a subset of individuals (the sample) selected entirely at random from a larger set (the population) by a process that ensures that: All individuals in the population are equally likely to be chosen for the sample.
In a political survey the margin of error varies depending on the candidate, that is, it depends on the geographic distribution of his constituency, so it is necessary that this type of survey be carried out within a confidence interval, value agreed by the client and the research institute .
In political research the standard of the confidence interval is 95%, what does that mean? This means that the candidate has a 95% chance of being within the margin of error and 2.5% of being above it and 2.5% of being below it. For example: suppose that in an election poll a candidate appears with 23%, taking into account the margin of error of 2.5%, he will be between 20.5% and 25.5%.
Because of this margin of error, when announcing the fall or rise of a candidate, it is valuable that successive surveys are carried out, comparing only the current survey with the previous one will give an answer with the possibility of much greater error.
Focus groups are usually a group of 10 or fewer people who come together to discuss a particular topic, product or idea. Focus groups are a tool used in the advertising and market research industry and are commonly used to measure the potential impact of a product.

The bystander effect
Explanation:
The bystander effect is the famous term in social psychology. It occurs when people discourage to help who is in need because of other people present. The bystander number will impact the situation. The greater the number of the bystander, less likely to help a person who is in need or distress. People take action seriously when there is no presence of other eyewitnesses. Latane and Darley was the founder of the bystander effect.
