Answer:
This is not my answer, I found it on the internet.
No more solutes can be dissolved in a saturated solution at a given temperature and pressure.
Explanation:
A saturated solution is a solution that consists of maximum amount and concentration of the solute that is dissolved in the solvent.
The extra amount of solute cannot be dissolved in a saturated solution.
The saturated solution is composed of solute and solvent and solvent cannot dissolve more solute at some extent.
The carbonated beverage is an ideal example of saturated solution.
Answer: Cell number one is an hypotonic solution, cell number two is an isotonic solution, and cell three is an hypertonic solution.
Explanation:
Cell number one which is a 98% water content is added the 100% water solution, water moves from low to high concentration. Therefore, the water moves from the solution into the cell, which is hypotonic.
Cell number two which is a 98% water content added with a 98% water solution. These two solutions are equal to one another, so the water does not move. This is isotonic.
Cell number three which is a 98% water content added with a 80% water solution. Water moves from high to low concentrations, so water moves from the cell to the solution. The water leaves the cell, which is an hypertonic.
9: Well big groups of birds are often found competing for food, causing fights and even death due to the fight. If a flock of birds from population A goes to population B, there would be more competition due to birds wanting food and nesting places that are good.
10: Many species evolve to suit environmental changes, but let's say this change in the environment was bad. Pollution, species of aggressive animals, which would eat the food the animals need and cause a downgrade in food leaving the area bare, and hunting, which would bring humans to the area and cause them to camp out, eat the animals and wild vegetables, such, can cause negative population changes. Due to these things birds could get sick and die off, causing population to go down. If trash and sewage are not cleaned up it could affect the birds food source and cause it to be bad for a long time, the aggressive animals would kill and eat the birds causing a continuous spiral of death, and hunting could cause them to die.
I am certain your answer is true.good luck
selective breeding has changed organisms over time by paring that organism up with another organism of its kind with desirable traits. take dogs for example, through selective breeding we now have many different types of dogs with different abilities. i hope this helps
