An action potential is an excitatory presynaptic nerve. An EPSP (Excitatory postsynaptic potential) takes place in the dendrites of the postsynaptic nerve. This spreads passively to the axon hillock. Depolarization of this region opens voltage-gated ionic channels. Sufficient membrane depolarization to threshold opens enough to these channels to produce an action potential.
Non myelinated axon; the currents associated with the action potential spread to the depolarized region of the axon.
In myelinated axon; the currents associated with the action potential spread to the next Node of Ranvier.
The action potential travels down the axon to the axon terminals.
Answer: protein structure
Explanation:
In Sickle-cell anemia, the gene sequence of hemoglobin is changed in its sixth position due to the substitution of glutamate with valine.
So, since glutamate, an amino acid soluble in water due to its hydrophilic side chain is substituted with valine, an amino acid that has a hydrophobic side chain insoluble in water or bloodstream; the resulting hemoglobin protein is altered in structure (sickle shaped) and unable to bind and transport oxygen efficiently to the various body parts.
The answer could be positive 24 and 25. And negative 24 and 25 since a negative times a negative equals a positive
A group of dolphins is called a pod. This is the same for whales.
