I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.

The probability that a homozygous recessive individual would be producing a dominant allele would be 0%. If expressed as a percentage, this is because the individual does not even have the possible allele in its genotype for whatever trait or feature that the protein codes for.

Answer:
There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.
The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.
In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).
Hope that answers the question, have a great day!
