<span>both excitation and inhibition</span>
The answer is graded potential<span>. Its made of various action potentials that depolarise the neuron incrementaly, in short interspersed intervals that do not give time for the neurons to return to resting potential. Therefore, the actions potentials, of varying sizes, grade up in sum and when they cumulatively reach the threshold level, they invoke an impulse in the nerve</span>
Answer:
Option B
Explanation:
The seven stars are bigger in size as compared to the size of the sun. Also, these stars are more luminous as compared to sun. However, these stars appear small in size in comparison to sun because of their distance from earth. The larger is the distance, the dimmer is the star. Sun is at a distance of 0.0000158 Light years from Earth while the nearest star of the seven sister i.e Alpha Centauri is 4.37 light years away.
Hence, option B is correct
Answer:
The correct answer will be- nasal septum
Explanation:
The nasal cavity is the hollow space or cavity connected to the two nostrils which allow the inhalation and exhalation of the air into the nose.
The nasal cavity is divided into left and right portion by a cartilaginous bony structure called nasal septum. The nasal septum lies in the central position and divides the nasal cavity into symmetrical portions.
Thus, the nasal septum is the correct answer.
