Answer:
From solutions that evaporate
Explanation:
Minerals can form in different ways. According to the question, minerals crystallize from a material dissolved in water when the solution evaporates. When a material dissolves in water, it forms a solution i.e. water + dissolved material.
The element constituents of the solution can aggregate to form a solid mineral, which will be left to crystallize when the solution undergoes evaporation i.e. liquid changes to gas. A very good example is when salt dissolves in water to form a salt water solution. When the water of this solution evaporates, salt crystals are left, which can crystallize to form minerals.
When we mix sand and water, no reaction takes place. The sand simply settles down at the bottom of the water container. This is because sand is heavier than water and hence cannot float in water. ... In comparison, if we mix something like salt or sugar in water, they will react and make the water salty or sweet.
Answer:
30...365; observe the ratio.
Your answer is true according to my teacher
In labs they try to collect 2-5 mL of VH and at least 25 mL of heart blood, 10 mL of peripheral blood, and 50-gram tissue samples from the subject's brain, liver, and kidney. All I know for the urine is that they request it in a small cup.
