Answer:
they use symbols to represent land features.
Explanation:
If we compare a cell with an egg there is a major difference between the outer membrane
in case of cell they are bounded by semi permeable membrane
The semi permeable membrane is a selectively permeable membrane which allows the movement of only solvent molecule and not solute molecules through it.
So water can move into or out of the cell through cell membrane by a special physical process known as osmosis.
the water will move from a low concentration gradient to high concentration gradient.
The density of a substance can simply be calculated by
dividing the mass by the volume:
density = mass / volume
Therefore calculating for the density since mass and volume
are given:
density = 46.0 g / 34.6 mL
density = 1.33 g / mL
Look at the periodic table (Boron has 3) and count up from there
