Answer:
<em>The </em><em>significance</em><em> of</em><em> </em><em>chemical</em><em> </em><em>formula</em><em> is</em><em> </em><em>that </em><em>it </em><em>tells </em><em>us </em><em>a </em><em>lot </em><em>about </em><em>the </em><em>chemical</em><em> </em><em>reaction</em>
<em>like </em><em>the </em><em>name </em><em>of </em><em>elements</em><em> </em><em>involved</em><em> in</em><em> it</em><em>,</em><em> </em><em>number</em><em> of</em><em> </em><em>atom </em><em>of </em><em>each </em><em>element</em><em> </em><em>and </em><em>it </em><em>also </em><em>shows</em><em> </em><em>that</em><em> </em><em>which </em><em>type</em><em> of</em><em> </em><em>reaction</em><em> is</em><em> </em><em>going</em><em> on</em>
<em>like </em><em>exothermic</em><em> </em><em>and </em><em>endothermic</em><em>,</em><em> </em><em>combination</em><em>,</em><em> decomposition</em><em> </em><em>etc </em>
<em>hope</em><em> it</em><em> helps</em>
Answer:
The nervous system releases neurotransmitters at synapses at specific target cells & The endocrine system reacts more slowly to stimuli, often taking seconds to days.
Explanation:
The nervous system is very specific with where the neurotransmitters go so they will affect target cells. The endocrine system is slower than the nervous system because the hormones travel through the blood so it takes much longer to reach the designated area.
Starfish has a endoskeleton
a coral has a exoskeleton
sponge has neither
Answer:
The correct answer is option B. The contraction forces of the innervated muscle fibers.
Explanation:
Electromyography or EMG is the study of muscle activity with the help of analyzing electric signals that are burst or generated by the contraction of the muscle fibers. In other words, it is the electrical activity of the skeletal muscles in response to a nerve's stimulation of the muscle.
EMG uses the myoelectric signals to analyze muscle that is generated during the contraction forces of the inverted muscle fibers of the skeletal muscle.
Thus, the correct answer is option B. The contraction forces of the innervated muscle fibers.
