How could you determine the best concentration of solutes to give to a patient in need of IV fluids before you introduce the fluids into the patient's body?

Answers

You would consider the route of administration, for sure. Is the fluid going to be introduced orally? Through an IV line? Knowing the patient's current fluid and electrolyte levels in their blood would be highly helpful. If you put hypertonic solutions in the the body orally, water will be shifted from the circulatory system into the bowel. This may help someone with fluid overload in their blood to remove some of the water from their blood. It would also help to add water to the stool in the digestive system and act as a laxative. (Osmotic saline laxatives work in this manner. If you put hypertonic solutions in an IV you will pull fluids from the interstitial space between cells as well as from the bowels to the circulatory system. This would help reduce edema. If you put hypotonic solutions in the body orally, water will shift from the digestive system to the circulatory system (and will also dilute electrolytes in the circulatory system). This method may be used to reduce electrolyte concentrations in the blood, and to hydrate the circulatory system in general. If you put hypotonic solutions in an IV you would dilute electrolytes in the circulatory system and would shift fluid to the interstitial space between cells. Isotonic is probably the best way to go if you don't want to shift fluids or change electrolyte concentrations in the circulatory / digestive system. 0.9% saline would be an example of this, and is generally the most widely-used solution for basic rehydrating someone through an IV.

How can changes in trophic levels affect an ecosystem’s health and stability?

Answers

Answer:

Changes in the basal levels that are on the bottom of the food chain.

Explanation:

Trophic levels are represented by steps in the food chain. In a simplified diagram, the first basal level is represented by primary producer organisms that include plants and algae. The herbivores are localized in the second place, while in the final levels it is possible to find carnivores and predatory species. It is well known that the changes in the basal trophic levels of this chain (i.e., changes in the first and the second levels) may alter the equilibrium of the food chain and consequently have effects on the stability of the ecosystem.

Explain the energy transformation that occurs when a person exercises.

Answers

AnswerYou could use the better version of the internet

Explanation:

Answer:

Electrical energy is defined as the energy flowing through a device due to the flow of electrons or charges from one point to another.

The energy present within an object or material due to the sum of its motion and potential energy is known as mechanical energy.

Thermal energy is defined as the energy present within an object because of the motion of its particles.

So, when we plug in and turn on a hair dryer then electrical energy starts to flow. As a result, some of its molecules will gain kinetic energy and some will have potential energy.

Hence, its sum will lead to formation of a mechanical energy. Since, this mechanical energy gets converted into thermal energy due to which hairs get dry.

Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.
