Dependent variable: rats ability to solve the maze (depends on caffeine)
independent variable: 100 rats (stays the same and is not affected)
The energy transfers in cellular respiration is different for because in photosynthesis because photosynthesis uses energy from the sun to create sugar for the producers while in cellular respiration glucose and oxygen that are converted into carbon dioxide and water.
Explanation:
in photosynthesis plants use the rays from the sun to produce sugar to create energy,but in cellular respiration glucose and oxygen are used to create carbon dioxide and water
Answer:
The neuron will not fire an action potential.
Explanation:
The missing magnitudes of the synaptic potentials when they reach the postsynaptic cell's axon hillock are:
A. excitatory +7
B. excitatory +10
C. inhibitory -3
D. excitatory +2
E. inhibitory -4
To fire the action potential, the summation of excitatory postsynaptic potentials (EPSP) and inhibitory postsynaptic potentials (IPSP) must reach the action potential threshold, which in this case is 15mV more positive than the resting potential.
The EPSP are: +7 +10 +2= +19
The IPSP are: -3 - 4= -7
EPSP + IPSP=
+19 -7 = +12 mV
The neuron will not fire an action potential since the integration of EPSP and IPSP is below 15mv.
