Driving while sleep impaired is much safer than driving while intoxicated. Please select the best answer from the choices provided T F.

Answers

Answer:

false but both are unsafe

Explanation:

Driving while sleep-impaired is not safer than driving while intoxicated. In fact, it is just as dangerous, if not more so. Hence the statement is false.

Driving while sleep-impaired is a serious problem that can lead to accidents, injuries, and even death. When you are sleep-impaired, your reaction time is slowed, your judgment is impaired, and your coordination is decreased. These factors can all contribute to dangerous driving behaviors.

A study by the National Highway Traffic Safety Administration (NHTSA) found that drivers who are sleep-deprived are 7 times more likely to be involved in a fatal crash than drivers who are well-rested.

The study also found that drivers who are sleep-deprived are more likely to make mistakes, such as drifting out of their lane or failing to yield the right of way.

Therefore, the statement "Driving while sleep impaired is much safer than driving while intoxicated" is false.

what percentage of the water entering the small intesneine is not absorbed during the digestive process

Answers

Almost all ingested food, 80 percent of electrolytes, and 90 percent of water are absorbed in the small intestine. Although the entire small intestine is involved in the absorption of water and lipids, most absorption of carbohydrates and proteins occurs in the jejunum.

The 10% of the water entering the small intestine is not absorbed during the digestive process.

What is the Digestive process?

The digestive process may be defined as a type of process that significantly deals with the organs that take in food and liquids and ultimately break them down into simpler substances so that the body can utilize them for energy production, growth, and tissue repair.

It may be thought that 90% of the water entering the small intestine is absorbed during the digestive process. This percentage of absorbed water constitutes either liquid or solid food. Apart from this, 95% of the carbohydrates and protein you consume are absorbed in the small intestine during the same process.

Therefore, 10% of the water entering the small intestine is not absorbed during the digestive process.
