Human trials have indicated an inverse relationship between blood lead level and calcium intake. While milk isn’t an antidote to let’s say, lead poisoning, the dietary calcium inhibits the lead absorption. This sort of poisoning is incredibly dangerous to the systems of the human body, and the ingredients within the milk help to defend against it. The purpose of the milk is to dilute the ingested poison.

Answer:
The correct answer is c. water to move out of the strawberry, making it smaller
Explanation:
Osmosis is the process refers to the movement of liquid molecule from the area of high solute concentration to an area of low solute concentration through a semipermeable membrane to equalize the osmotic balance.
Osmosis is important for any cell to maintain a proper osmotic balance of the cell. So if sugar is sprinkled on a strawberry the solute concentration outside the strawberry cells will increase which will result in water release from the cell.
This release of water from the cell will shrink the strawberry and make it small. Therefore the correct answer is c.
Answer:
B. The amount of lee that melted.
Explanation:
The dependent variable is more of what results from an action during an experiment. It is actually what is being tested for. In the experiment, the scientist seeks to understand the effect of salts on melting point of ice. He selects the different salts which can cause a ice to melt (independent variables) then he sets up to find out the effect of the salt on the ice.
He cannot control how much ice will melt. The properties of the salts would determine the extent and rate of the dissolution of the ice pack. This is the dependent variable which relies on the nature of the salt.
