Bacteria are tremendously successful unicellular organisms, yet all large organisms are multicellular. unicellular organisms cannot grow very large because the -
a respiratory rate would be too high
b diffusion of nutrients into the cell's interior would be too slow
c energy expenditures would be too great
d locomotion of the organisms would be too slow

The movement of tectonic plates in two different locations is shown below: two blocks labeled location a and location b are shown. at location a the top layer of the block shows two horizontal arrows pointing towards each other. small dunes are shown in the middle between the two arrows. the block labeled b has a vertical line in the middle. on the left of the line there is an arrow pointing down. on the right of the vertical line there is an arrow pointing up which statement is most likely true? subduction may occur in both locations. earthquakes may occur in both locations. subduction may occur in location a only and a volcanic eruption may occur in location b only. an earthquake may occur in location a only and a volcanic eruption may occur in location b only.

Me . based on the data in your tables, did the light-colored moths have a higher or lower survival rate after the industrial revolution?

The table shows dates and appearance of index fossils. which rock layers can be dated most precisely? a) a layer containing both a fossil 4 and a fossil 3 b) a layer containing both a fossil 2 and a fossil 3 c) a layer containing both a fossil 1 and a fossil 4 d) a layer containing both a fossil 1 and a fossil 2
