Answer
An acid that breaks down completely and gives off many ions, or protons, is considered to be a strong acid. ex H₂SO₄
If you place strong acid into water it dissociate acid into H⁺ ions
Water is polar solvent(H⁺ and OH⁻), which has partial positive charge on one side and partial negative charge on the other side.
Strong acids readily dissociate in polar solvents to give H+ ions.
Where as Oil is a non polar solvent it has same charge all over so no dissociation of strong acid will take place.
Answer:
Motor neurons stimulate muscles to contract answer:C
No, some animals (at the bottom of the food chain) suffer according to natural selection while other animals who are stronger (likely predators) Will succeed more and have a better chance of survival
Passive Transport: Simple Diffusion
Diffusion across a cell membrane is a type of passive transport, or transport across the cell membrane that does not require energy. Remember that the cell membrane is a phospholipid bilayer. Although the inside and the outside of a cell are both water-based, there is a hydrophobic region in the middle, and this is an important barrier to anything large, charged, or hydrophilic. Molecules that are hydrophobic, just like the hydrophobic region, can pass through the cell membrane by simple diffusion.
Therefore, simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules from a higher concentration to a lower concentration. Very small molecules can slip through the cell membrane, too, even if they are hydrophilic - just like a few ants might crawl through a crack in the wall just because they're tiny.
