When the concentration of ________ in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.

Answers

When the concentration of electrolytes in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.

OSMOSIS:

Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.

Osmotic principle is based on concentration gradient i.e. difference in concentration across a membrane.

Electrolytes represent solute such as salts, ions, sugar etc. Therefore, when the concentration of electrolytes in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.

What are the two ways that harmful algal blooms can negatively impact an ecosystem? (Site 1).

Answers

Answer:

SEE EXPLANATION FOR ANSWER

Explanation:

Eutrophication: An abundance of cyanobacteria (an algal bloom) is caused by an excess amount of nutrients in the water (phosphorus and/or nitrogen) which depletes the water of oxygen which is vital for plant an animal life. Oxygen is crucial for the survival of an organism, so when there is a lack of oxygen, the results can be fatal. That is why when there are reports of algal blooms, there are almost always mentions of an abundance of dead fish, birds, and other water dwelling organisms (these organisms live in the water, drink from it or use it as breeding grounds etc,) Not only that, but algal blooms produce toxins that can make animals and humans fall ill.

Dead zones: As stated previously, harmful algal blooms deprive the water of oxygen.This can lead to the extreme and create dead zones. Dead zones are zones in an aquatic body where the oxygen levels are not sufficient enough to support aquatic life. Hence why there is no life in dead zones because all of the fish either die, or leave.

Both affect the population of native species and the overall wellbeing of the bodies of water.
