Question 2
adding more solute to a solvent
a)decreases its boiling point
b)does not affect its boiling point
c)increases its boiling point
d)increases its freezing point

Adding more solute to a solvent increases its boiling point

Explanation:

Remember the colligative properties, in this case boiling Point Elevation.

Look at the formula

ΔTb = Kb · m

- where ΔTb  is the difference between T° eb of solvent in solution - T° eb of solvent pure

- Kb is the the molal boiling point constant

- m is molality (moles of solute / kg of solvent)

When you add more solute, you are increasing molality, so as Kb is constant and T° eb of solvent pure we also know it, you are always increasing ΔTb, that's why T° eb of solvent in solution is more higher.

i think that d. wind is the answer.   i missed the question when i answered a. currents.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
