When looking at a competitive interaction between mice (species 1) and rabbits (species 2), you determine the competition coefficient for mice on rabbits (alpha) is 0.25. How many mice would need to be added to the mouse population to have the same effect as adding one rabbit to the rabbit population (relative to resource use and carrying capacity)

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later.when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )

What kind of seafood would you expect to have the highest levels of mercury and why? kelp, because they use the sun to photosynthesize on the bottom trophic level. oysters, because they filter feed on plankton on a lower trophic level. small fish, because they eat plankton on a higher trophic level. sharks, because they feed on organisms on a higher trophic level.
