What is the difference between osmosis and diffusion?

a. osmosis moves molecules, such as water, through a semipermeable membrane. diffusion moves molecules, such as oxygen and carbon dioxide, through a permeable membrane.

b. osmosis allows all molecules to move from areas of higher concentration to areas of lower concentration. diffusion allows only water molecules to move from areas of higher concentration to areas of lower concentration.

c. osmosis requires facilitation by a channel protein. diffusion requires additional energy from an energy-carrying molecule like atp.

d. osmosis occurs over an area called a concentration gradient. diffusion occurs over a membrane bilayer.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.  

do yall know the answer?
