Answer:
Depolarization necessary to cause an action potential.
Explanation:
To achieve an action potential, you need to change the resting membrane potential from about -70 mV to +30 mV. This occurs by the influx of Na ions.
Now in order for this to happen, Na ions diffuse down electrochemical gradient to make the inside of the cell less negative. This effect is achieved by the opening of some Na+ voltage-gated channels.
To achieve the change from -70 mV to +30 mV, all the sodium voltage gated channels will need to open. This happens if the stimulus is strong enough to reach a potential of about -55 mV (threshold stimulus).
The concept behind this is positive feedback. The more depolarization there is, the more is the number of opened Na voltage gated channels.
Domain genes are stronger than ressive genes.
<h3>What is genes?</h3>
the word gene can have several different meaning if The Mendelian gene is an basic unit of heredity and it is to the molecular gene is a sequence of nucleotides of in DNA that is transcribed to the produce a functional by RNA. There are two types of to the molecular genes: is to the type of protein-coding of the genes and noncoding genes.
When an allele is dominant, the characteristics it is be connected to will be the expressed in an individual. When an allele is recessive, the characteristic it is most connected to is less likely to be expressed. Recessive to the traits only manifest when both alleles are the recessive in an individual.
