7. which type of transport below moves water through a selectively-permeable membrane from areas of greater concentration to areas of lesser concentration?
a. diffusion
b. facilitated
c. osmosis
d. chain-reactive
8. diffusion occurs to ultimately reach or an even distribution of molecules throughout a given space (remember the yellow dye in water? )
a. equilibrium
b. instability
c. high concentration
d. low concentration
9. water movement into and out of a cell is dependent upon the surrounding the cell.
a. temperature
b. environment
c. number of lipid molecules
d. total number of phospholipid molecules in the cell membrane
10. which comparison of osmosis and diffusion is accurate?
a. osmosis moves molecules, diffusion moves water
b. diffusion moves across a selectively-permeable membrane, osmosis does not involve a membrane
c. both move molecules up a concentration gradient
d. osmosis moves water down a concentration gradient, diffusion moves molecules down a concentration gradient

Most of earth’s fresh water is found in oceans and seas stored in glaciers and ice caps groundwater stored beneath the surface found in lakes, rivers, streams, and reservoirs

What is a cordon and where is it found

Which of the following scenarios is an example of the bottleneck effect? answers a in south africa, much of the afrikaner population is descended from a small number of dutch colonists. in this population, this is an unusually high frequency of pseudoxanthoma elasticum (pxe), an elastic tissue disorder. b four white-tailed deer are introduced to a park in finland. thirty years after their introduction scientists compare the genes in the population and find that there is no variation. c during the industrial revolution, london's air became filled with soot. as a result, birds started eating more of the lighter moths because they were easier to spot than their darker counterparts. over time, the moth population changed so that there were more darker moths than lighter ones. d 10% of the population of american alligators in an area have the recessive trait albinism. a massive flood results in the death of 80% of the population. of the remaining population, 60% have the recessive trait of albinism.
