Answer:
Non polar molecule, small
Explanation:
Cell membrane is a selectively permeable membrane.
Factors that affect permeability of a molecule are-
A. Size - Small molecules can easily pass through the membrane than the large molecules.
B. Solubility - Non polar molecules ( eg. carbon dioxide) are lipid soluble in cell membrane , so they can easily pass through the membrane than the polar molecules (eg. glucose)
Explanation:
Volcanoes produce geothermal energy, which are used to generate heat. When a volcanoes erupts, a large amount of ash is ejected. This ashes can be extremely damaging to the environment in the brief period, but over time, the ash layer, which includes many valuable minerals, will be transformed into a highly productive soil.
1) heat flows from hot to cold. the heat from the fire is let off from the exothermic reaction of the fire and warms up the surroundings, including yourself.
2) food is cooked in the oven by heat transfer. the heat warms up the pan and thru conduction, the food is heated and cooked.
3) I'm guessing this question is y it heats up? the answer to that is that the heat waves from the sun is absorbed into the car from radiation and thru convection the whole car is heated
