Osmosis is the diffusion of water across a selectively permeable membrane in which water moves from a solution containing a low concentration of solute to what kind of solution?   a. a solution containing the same amount of solute     b. a solution containing only the solute     c. a solution containing a high concentration of water     d. a solution containing a high concentration of solute

D. a solution containing a high concentration of solute

Explanation:

Water alongside solutes tends to naturally move in the environment i.e. to and fro a cell. This movement is achieved when an osmotic gradient is formed during OSMOSIS. Osmosis is the movement of water from a region of low concentration of solute (high concentration of water) to a region of high concentration of solute (low concentration of water) through a semi-permeable membrane (usually the plasma membrane).

The difference in solution concentration between a cell and its external environment creates the OSMOTIC gradient. Water moves until an equilibrium is achieved in both the cell and environment.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
