Which statements best describe gases? Check all that apply. The atoms in a gas move at high speeds. The atoms in a gas often get stuck together. The atoms in a gas spread in all directions. Gases have a definite shape. Gases have a definite volume.

Answers

Answer: The atoms in a gas move at high speed.

The atoms in a gas spread in all directions.  

A gas is a state of matter in, which atoms remains in a constant motion, they do not stick together. They are free and can move in all directions. The gas molecules expands to fill the available space. Hence, they can change shape and volume. The gas atoms being in a molecular state moves fast in high speed to break away from each other, to remain in a free state.  


Gases do not have a definite shape or volume rather they spread out to fill in the container and take its shape and volume.

According to the kinetic theory of gases, particles of a gas move at high speeds and collide frequently with each other as well as with the walls of the container.

The following are true regarding the movement of gas particles;

  • The atoms in a gas move at high speeds.
  • The atoms in a gas spread in all directions.

Gases do not have a definite shape or volume rather they spread out to fill in the container and take its shape and volume.

A client is receiving total parenteral nutrition (tpn). the nurse notices that the bag of tpn solution has been infusing for 24 hours but has 300 ml of solution left. the nurse should: discontinue the current solution, change the tubing, and hang a new bag of tpn solution. notify the health care provider (hcp) and obtain prescriptions to alter the flow rate of the solution. change the filter on the tubing and continue with the infusion. continue the infusion until the remaining 300 ml is infused. submit answer

Answers

If the nurse notices that the bag of TPN solution has been infusing for 24 hours; not minding how much of the solution is left, the nurse should discontinue the current solution, change the tubing, and hang a new bag of TPN solution. It is not safe to hang a bag of TPN for more than 24 hours due to the risk of infection.

Total Parenteral Nutrition contains calories that are calculated to provide nutrients in the body and is only good for 24 hours at room temperature thus the nurse should discontinue the current solution eventhough there is still remaining 300 ml of solution.

How do industrial melanism, insecticide resistance, and antibiotic resistance all support the idea of evolution and natural selection?

Answers

Industrial melanism is the resultant effect of industrial pollution on arthropods. The individuals that had a darker pigmentation were more fit to the new environment, more polluted that caused darkened buildings and trees, and were thus favoured by natural selection to survive.
Insecticide resistance and antibiotic resistance is also a manifestation of the emergence of new groups of organisms that are resistant to a specific attack out of an existing population, and are therefore favoured by selection to survive over the others.

Insulin and glucagon release from the pancreas is a vital part of the negative feedback loop that regulates blood glucose levels. let's review how insulin and glucagon release change in response to plasma glucose levels and how that helps keep plasma glucose constant.

Answers

This negative feedback loop (something's wrong, fix it) is regulated by the release of insulin and glucagon through the islets in the pancreas. Insulin secretion is triggered by a high level of glucose in blood. Insulin causes a reaction in a numbers of cells, including muscle cells, red blood cells and fat cells to begin taking in and storing excess blood glucose, lowering the level of free glucose in the blood. Glucagon secretion, on the other hand, is triggered by a low level of glucose in blood. Glucagon causes a direct reaction in the liver, causing it to release excess glucose stored in its cells into the bloodstream, which raises the level of glucose. It also has the effect of instructing the liver and muscle cells, among others, to begin actually creating new glucose molecules out of the building blocks of other nutrients in the body.

Why is only one side of the moon visible from earth?

Answers

Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth, a situation known as synchronous rotation or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.
