The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
Explanation:
To dissolve, solvent particles must come in contact with solvent particles. Particles of hot water are moving much more rapidly than particles of cold water. Hence, in hot water more water particles will come in contact with hot chocolate powder than in cold water, resulting in faster dissolving.
The substance must be able to alter its physical characteristic (for example, its color) in accordance to a change in pH. One example of this is litmus paper, which becomes red under acidic conditions and blue under basic conditions.
I would help but this is the type of project to do on your own. I'd suggest planning out the image then building from there, or use graphs on the internet for inspiration. I wish you luck though :>
This is an opinion question, meaning that if you back it up well enough you can't be wrong
Pros to oceans-hydro power
- cleaner (aka better for the environment)
- long term sustainability
- less expensive in the long term
Cons
- initially more expensive
- more hydro turbines are required to offset the energy gained from 1 coal burning plant
- potentially harmful to (a very limited) marine ecosystem
Just pick a side and back it up.
