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 answer is in the question. It's called imprinting.
Answer:
Increase
I cant remember the lesson number but if the number of predators increase it would make many animals that are there prey to become scarce in the area the predators are in wich would make many predators starve so in order to avoid they would have to move out across more land to find more food
So
step 1 is: H= normal h= hemophilia
Step 2 is: HH x hh
Three:
All of there offsprings would be Hh 100%
