Transport proteins (carrier proteins and channel proteins) allow substances into and out of the cell that cannot pass through the phospholipid bilayer (as they’re either to large, charged or not lipid soluble) by facilitated diffusion.
Specifically channel proteins allow ions into and out of the cell by creating a pore in the membrane in which they can move through with their concentration gradient
Physical change. Boiling water does not change the fundamental properties of the water, as it can turn back into water during condensation.
A. Use a scale to measure the mass of a cup of water. Leave the cup out for one day and measure the mass again.
Explanation:
Jenny can predict is evaporation occurs by using a weighing scale to measure that mass of a cup of water, then he leaves the cup out for one day and he measures the mass again.
- If the mass remains the same, then evaporation did not occur.
- If evaporation occurs, then the mass will be lesser after the second measurement.
- From this Jenny can infer the mass loss and made good deductions.
- Evaporation is a phase change in which liquid turns to vapor.
