Answer:
When a neuron fires and its electric charge travels down the axon, causing neurotransmitters to be released by the neuron's terminal buttons, an <u>action potential</u> occurs.
Explanation:
An action potential, commonly termed as impulse, can be described as messages which are transferred in electrical form. Action potential are caused due to different electric charges. An action potential is generated by a stimulus which causes transfer of sodium ions into the axons resulting in depolarization of the neuron. To overcome this, potassium ion will enter the cell and an action potential will be generated.
The action potential causes release of the neurotransmitters so that signal messages could be transferred.
Answer:
Option D, 75%
Explanation:
Let the genotype of co dominant checkered hen mates and checkered rooster be CcC and CcC
Where Cc – is the allele for chekered skin
C – is the allele for non chekered skin
Co-dominant allele are those which irrespective of being dominant or recessive are expressed equally.
The punnet square for the cross between these two would be
Cc C
Cc CcCc CcC
C CCc CC
3 out of 4 offsprings have chekered allele i.e CcCc, CcC and CcC. Thus, the probability of chekered offsprings would be 75%
The ecosystem is very complex and simulations do not include all of the factors that may impact ecosystem processes.
I believe it's the long arm of chromosome 17.
