Explanation:

When an aqueous solution freezes, the unfrozen solution becomes denser. That's because some of the water has been removed as ice. However, the solutes remain dissolved in a solution with a smaller liquid volume. The concentration of the solution increases, so the density increases.

this is because water expands as it gets cold hence floating leaving the unfrozen water dense

5. Species with limited resources usually exhibit a(n) ________ growth curve

asambeis [7]

Answer:

The correct answer is: Species with limited resources usually exhibit a logistic growth curve

Explanation:

In ecology, logistic growth refers to the phenomenon where the growth rate of a population decreases as the population reaches its carrying capacity (the number individuals that an environment can support without facing degradation). To put it simply, when a certain species has limited resources available to them, as they reach their carrying capacity, the population of that species will decrease due to death caused by lack of resources for consumption. The attachment shows what logistic growth looks like when plotted on a graph.

How could you determine the best concentration of solutes to give to a patient in need of IV fluids before you introduce the flu

natima [27]

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.
