Answer:
When the molecules are too large.
Explanation:
Facilitated diffusion refers to the passive transport of substances down the concentration gradient via specific transport proteins present in the membrane. The large, polar, charged substances and ions cannot pass through the small spaces present between hydrophobic tails of membrane phospholipids. The transport proteins transport these substances in energy independent manner.
Answer:
They make trends in the data easier to see. They are easier to create than data tables.
When voltage of a plasma membrane shifts from +30mV towards 0mV, we say cell is repolarizing. Repolarization results from the movement of positively charged K+ ions out of the cell. This repolarization phase of an action potential results in hyperpolarization, attainment of a membrane potential that is more negative than the resting membrane potential.
Answer:
Solar panels can generate electricity just about anywhere on Earth, but some areas receive more sunlight than others, and as such, have a higher solar energy potential. The following map, prepared by Solargis, shows areas with the highest PV production potential.
