Please help me, I have an F in biology and if I get a good grade on this test, I could pass!! When the insects eat lichen, they are eating the sugar molecules that make
up the plant. The sugar molecule that stores the energy is called what?

Cellular Respiration
Carbon Dioxide
Photosynthesis
Glucose

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

1.the evidene of the reaction

2.yes

3.yes

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
