Answer:The Law of Conservation of Mass states that mass is conserved in physical and chemical changes. Students explore this concept by taking initial masses, making predictions, and finding final masses of physical and chemical changes. Students observe water changing from ice to a liquid, a piece of cardboard being cut up, salt dissolving in water, Alka-Seltzer reacting in water, and water's physical property of cohesiveness being disrupted by soap.

If you want to grow up a large quantity of streptomycin-resistant E. coli, you would require to pick a colony of the bacteria from the streptomycin-positive plate and allow to grow it on a streptomycin positive plate. 
<h3>What is E. coli?</h3>
E. coli may be defined as a type of bacterium that is commonly present in the intestinal regions of humans and other animals, some strains of this bacterium can significantly cause severe food poisoning.
The strain of streptomycin-positive is those population of E. Coli which is significantly streptomycin resistant, while the negative strain has the opposite effect. 
That's why if you want to grow up a large quantity of streptomycin-resistant, you must remarkably require to pick only a positive strain of streptomycin for E.Coli bacterium. 
Therefore, if you want to grow up a large quantity of streptomycin-resistant E. coli, you would require to pick a colony of the bacteria from the streptomycin-positive plate and allow to grow it on a streptomycin-positive plate.

Answer:  It will slow down.
Explanation:  This is because the same amount of blood that usually goes through will have to fit through a blocked vessel.  Only a little will be able to go through at one time, causing the blood flow on the other side to slow.
(That is really dangerous.  The build-up will eventually burst the vessel)  Just an FYI
