The answer is (b). The hydrophobic sequence of AA is not electrically charged so it isn't soluble in water that means it spans the membrane. The
hydrophilic sequences are attracted by water and they remain in the aqueous enviornments on the two sides of the membrane. This diagram should clarify.
A natural resource is a material that occurs in nature and can be used for economic benefit. (ex. coal, minerals, soil)
False. wind direction is just caused by differences in pressure.
Water molecules will pass through the cell membrane into the cytoplasm of the cell causing it to swell and become turgid until it get to the elastic limit where the cell splits or burst
