While norepinephrine is majorly a neurotransmitter (in synaptic transmission)
, it also acts as a hormone produced by
the adrenal gland. It is usually secreted as a stress hormone, just like
cortisol. It increases heart rate, blood flow
in skeletal muscles, production of glucose by the liver, especially in the
fight-or-flight response.

Answer:
The muscle fibers are pulled by the myosin and sarcomere together, resulting in the shortening of the fibres, but the sarcomere and myosin just move.
Explanation:
During muscle contraction, each sarcomere shortens, bringing the Z discs close together. There is no change in the width of the A band but both I bands and the H zone almost completely disappear. These changes are explained by actin and myosin filaments sliding past one another, so that the actin filaments move into A band and H zone. Muscle contraction thus results from an interaction between the actin and the mosin filaments that generates their movement relative to one another. The molecular basis for this interaction is the binding of the myosin to actin filaments that generate their movement relative to one another.
In the solar system there is a lot of distance between mars and Jupiter. the main asteroid belt is in this area. what is the reason a planet did not form between mars and Jupiter
a. Planets can only form close to the sun or far away from the sun. This area is a region where planets cannot form
b. This area gets a lot of stellar wind from the sun. planets cannot form in areas that get a lot of stellar wind
c. Mars has two very fast moving moons, these moons prevented a planet from forming in the area.
d. Jupiter's gravity affect this area so much that no planet could form there.

No.
