Answers
Answer:
•the air,no longer in contact. •(I'm not sure but I think its )•gradient. a concentration gradient
The molecules in the box on the right are in low concentration gradient. The box on the left has an area of high concentration and an area of low concentration. Scientists would say there is a concentration high concentration gradient.
What is the concentration gradient?
The concentration gradient is the presence of a substance at a specific place. A low concentration gradient means when a substance is dispersed and present far from each other.
A high concentration gradient means when there is a large amount of substance present in a place. These words are used when there is transfer of molecules along the plasma membrane.
Diffusion and osmosis are the two processes by which the transfer of molecules happens.
Thus, a = low concentration gradient., b, = high concentration gradient.

both carbohydrates and fats provide erorgy, why is it that you get a sugar high,
ut not a fat high?
Answers
Answer: The body uses three main nutrients to function --- carbohydrate, protein, and fat. These nutrients are digested into simpler compounds. Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins.
Cells in the pancreas can release glucagon, a hormone that signals the body to produce glucose from glycogen in the muscles and liver and release it into the blood.When glycogen is used up, muscle protein is broken down into amino acids. The liver uses amino acids to create glucose through biochemical reactions.Fat stores can be used for energy, forming ketones.Other hormones can raise the blood sugar level, including epinephrine (also called adrenaline) and cortisol released by the adrenal glands and growth hormone released by the pituitary gland.sorry if im wrong and have a wonderful day kind person!!!!!!

Transpiration is the rate of the water vapour exhalation by the plant cells through its opening pores. The correct blanks are guard cells and closing.
What is the structure of plant cells regulating transpiration?Plant cells have certain specialized cell organelles that help in maintaining the rate of the carbon dioxide and the water content in their cells.
Stomata of the plant cells are specialized organelles that maintain the water and rate of transpiration by the plants. They have guard cells surrounding them that regulates their opening and closing.
The guard cells of the stomata form pores of the stomatal opening. The opening and the closing of the pores are regulated by the bulge and the carbon and the water intake and outtake of the cell is maintained.

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
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.
