Which of the following choices correctly matches a tool and its proper application?
transmission electron microscopy (tem) to study the movement of organelles within a living cell.
scanning electron microscopy (sem) to study the detailed movements of living cells.
light microscopy to study the internal structure of cilia.
transmission electron microscopy (tem) to study the surfaces of preserved cells.
cell fractionation to study the function of specific organelles.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
