What attraction does the positive ab have with the negative ab?
Answer:
The correct answer is - The neuron's intracellular charge must get more positive to meet a certain thresh hold in order to depolarize. If the neuron does not hit that threshold, then the neuron will not fire
Explanation:
In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.
If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.
Answer:
<em>The correct option is C) Mitochondrial DNA can be traced for generations.</em>
Explanation:
The mitochondria are the organelles of the animal cell which contain their own genome. This genome also has the ability to produce proteins. The mitochondrial DNA passes from the mother to the children and remains identical. We can say that the mother and the children will possess the same mitochondrial DNA. In this manner, the mitochondrial DNA can be traced for generations as it remains the same for generations.
