Answer:
See the answer below
Explanation:
The sympathetic and sympathetic nervous systems make up the autonomic nervous system, regulating involuntary functions. The first acts in situations of fight or flight, for example in an accident of self-actions such as: increased heart rate, pupil dilation, relaxes airways, among others. Neurotransmitters are released: adrenaline and norepinephrine. The parasympathetic system performs antagonistic functions by activating in relaxation situations: it decreases heart rate, contracts pupils, constricts airways. Acetylcholine is released as a neurotransmitter.
In some cases yes. Kids tend to learn faster than the average toddler.
Answer: Refractory period of the cardiac action potential
Explanation:
Unlike the skeletal muscle which can be reactivated before it reaches a contraction, cardiac muscle must wait before it is almost completely relaxed to be activated again (because of its long refractory period), so one cannot make an increase in strength of contraction with a high frequency of stimulations.
Organic and Natural are the legal terms used If meats come from animals that were raised without antibiotics or hormones
<u>Explanation:</u>
Meat, poultry, eggs, and dairy products labeled “organic” have must come from an animal that is managed without "antibiotics, combined growth hormones, mammalian byproducts, or other forbidden fodder ingredients". They are also labeled as "Natural".
According to USDA, “natural” meat and animal farm products should not include synthetic pigments, unnatural flavorings, chemicals or other synthetic components, and they should be “minimally treated”. However, this label does not reveal how the animals were grown, what they were served if antibiotics or hormones were used, or other perspectives of production that purchasers might reasonably expect from something designated “natural.”
