Answer: The amount of energy lost by the metal is equal to the amount of energy gained by the water
Explanation:
Cylinder D
temperature is the measurement of average kinetic energy of a sunstance. since cylinder D has the highest average velocity, it has the highest average kinetic energy among the 4 cylinders, thus cylinder D is the hottest.
If they're different sizes and densities, you are able to separate the substances.
I believe that the correct answer would be energy since you need energy for any kind of chemical change to occur. I hope this helped you with your question! If you have any questions please let me know and I might be able to further assist you.
Answer:
Exposure of a red blood cell to a hypotonic solution causes swelling and eventual bursting of the cell membrane upon prolonged exposure.
Exposure of a gram positive bacterial cell causes the flow of water into the cell however, its rigid cell wall protects it from bursting.
Explanation:
A red blood cell has a cell membrane but no rigid cell wall. The inside of a red blood cell is <em>hypertonic</em> (contains more solutes like DNA, proteins) therefore, an exposure to a <em>hypotonic</em> solution ( solution with less solutes and more water), causes water to flow into the cell membrane by osmosis.
Osmosis is the movement of fluids from a region of higher concentration to a region of lower concentration. This creates a balance in fluid contents across both environments.
After prolonged exposure to the<em> hypotonic</em> solution, the flexible cell membrane swells and eventually bursts.
A gram positive bacterial cell has a rigid cell wall and a cell membrane. When exposed to a <em>hypotonic</em> solution, water flows from the outside environment to the interior of the cell by osmosis through the cell wall and membrane. The rigid cell wall of the bacterial cell however, contains the swelling and prevents the cell from bursting.
