The correct answer would be a positive feedback loop. when contractions happens its to help get the baby out and to let you know when the baby is coming so when the contractions start it means you are going into labor.
The answer is C respond to stimuli in the environment
Answer
Frequency of stimulus can change the force of muscle twitch.
Explanation
Twitch is tension produced by the contraction of a small muscle or it is muscle fasciculation. Its strength depends on the stimulation frequency. If the frequency is higher then temporal summation takes place and produce higher tension in the muscle. If the frequency is weak then less tension is produced in the muscle. This force also depends on the cross-sectional area of muscle.
Answer:
Clorofluorocarbonos
Explanation:
es decir, los compuestos que contienen cloro, flúor, carbono y posiblemente hidrógeno, se han utilizado ampliamente en las naciones industrializadas en las últimas décadas principalmente como propulsores en latas de aerosol, como refrigerantes y como agentes de expansión, por ejemplo, para producir espuma de poliuretano .

The fact that electrons occupy certain specified energy levels in which they are radiation less solves the problems associated with the Rutherford model.
<h3>What is the Bohr-Sommerfeld Model?</h3>
According to the Bohr-Sommerfeld Model of the atom, the electrons in an atom tend to occupy certain specified energy levels in which they are radiation less.
Recall that following from the Rutherford model and the and the Maxwell's laws, an accelerating charge radiates energy. Thus, the bottle neck is removed by assuming that electrons occupy specific energy levels in which they do not move about an loose energy.
This eliminates the possibility that the electron could spiral into the nucleus.
