Answer:
The simple answer is bioaccumulation resulting from biomagnification. Carnivores consume organisms at higher trophic levels, and thus "poisons," such as heavy metals accumulate in these organisms at levels greater than those found in plants. Moreover, such chemicals typically accumulate in the fatty tissues of carnivores, such as the nervous, lymphatic, endocrine, and reproductive systems.
put some water out with less salt and then some more water out with more salt and look at the differences with the freezing.

Answer: The concentration, in moles per litre, of a solution formed when 13.0 g of calcium hydroxide is dissolved in 5.0 L is 0.036 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,
n = moles of solute
= volume of solution in L
moles of
= 
Now put all the given values in the formula of molality, we get

Therefore, the concentration, in moles per litre, of a solution formed when 13.0 g of calcium hydroxide is dissolved in 5.0 L is 0.036 M
