Your answer is gonna be the first second and fourth options
Answer:
The initial effect of a stimulus on a sensory receptor is a small, local change in membrane potential called a(n) <u>receptor potential</u>.
Explanation:
The process used by sensory receptors to transform the physical energy of the sensory stimulus into action potentials, the fundamental unit of information in the nervous system, is called sensory transduction. The entrance of positive charges towards the interior (mainly Na +), will cause a depolarization; while if there is an exit of positive charges from the interior (mainly K +) then hyperpolarization will occur. This change in membrane potential is called the receptor potential. A receptor potential is then a local potential that can sometimes represent the only response that results from the transduction process, for example in the taste sensory cell.
Answer:
The movement of potassium ions out of the axon.
Explanation:
The membrane potential or cell potential is the difference in the electric potential outside and inside of the cell. The cell potential is important for the transmission of nerve impulse.
The resting potential of the cells is -70mV. The movement of sodium ions causes the cell depolarization and makes the membrane potential more positive. The cells sometimes attain the more negative membrane potential stage known as hyperpolarization. This state mainly occur by the efflux or the movement of the potassium ions out of the axon.
Thus, the correct answer is option (A).
The answer is it is sleeping
Answer:
3300 meters
Explanation:
so the formula is in the questtion
distance=speed*time
so distance=330*10
to get the units you have to look to see that the only unit that is a distance is meters
hope this helps!
