Biology
1 answer:
ss7ja [257]3 years ago
7 0

Answer:

Explanation:

pH is a measure of the relative amount of free hydrogen and hydroxyl ions in  water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.

Match the factors which affect the rate of dissolving/dissociation/diffusion. 1. increased surface area matching polarity 2. lik
Vlad [161]
<span>The pairs would be:

1. increased surface area  
</span>finely divided solute <span>
Increased surface area of the solute will make the solute </span>finely divided. Since the area of the solute that touches the solvent is higher. Since the area of work is bigger, then the work would be faster.<span>

2. like dissolves like 
</span>matching polarity<span>
Like dissolve like because a matter tends to clump up with the same kind of polarity. Water is polar and will be a good solvent for a polar solute because they can form hydrogen bond which makes it easier to spread.

3. temperature 
</span>rate proportional to kinetic energy 
The temperature rate proportional to the kinetic energy, which makes the molecules move faster. A faster movement will make it spread easier. That is why higher temperature will result in higher solubility and faster rate of <span>dissolving
</span><span>

4. stirring 
</span>spreads solute throughout solution
Stirring will help spread the solute. When the solution is not stirred, the solute that dissolved will be concentrated near the solute. This will decrease the rate of dissolving around it. Stirring help by moving the dissolved molecule away from the solute, makes the solute exposed more to the solvent.

Infer: Parrotfish rely on corals for protection and shelter. Look at the parrotfish population over time. Why did the parrotfish
Anna71 [15]

Answer:

Lack of shelter.

Explanation:

Although I cannot see the graph of the population over time, I am assuming it was exponentially rising and then began to decline. This is because the parrotfish were able to populate only until the species ran out of shelter. Once it ran out of shelter, the exposed fish began to die due to predators or the environment.

It may also be because of the drastic decline of living coral reefs. As coral reefs die, so do livable habitats for the parrotfish. As a result, the parrotfish decrease in population as fewer corals are available for the fish to live in.
