Answer:
The correct answer is A acetylcholine binds to a receptor protein on the motor end plate
Explanation:
The neurotransmitter acetylcholine is released by the motor neuron during the transmission of signals across a neuromuscular junction.
The released acetylcholine then diffuses the synaptic cleft and binds to the receptor protein present on the membrane of muscle fibre.
This ultimately result in the influx of sodium ion inside the muscle cell thereby causing depolarization to generate an action potential.
Percent error is calculated by the expression:
%error = |actual value - observed value| / actual value x 100
We calculate the error of the values as follows:
<span>a. 23.487 cm
% error = |</span><span>23.490 - 23.487| / 23.490 x 100 = 0.013%
</span><span>
b. 23.493 cm
</span>% error = |23.490 - 23.493| / 23.490 x 100 = 0.013%
<span>
c. 23.516 cm
</span>% error = |23.490 - 23.516| / 23.490 x 100 = 0.11%<span>
d. 23.501 cm
</span>% error = |23.490 - 23.501| / 23.490 x 100 = 0.05%<span>
e. 23.477 cm
</span>% error = |23.490 - 23.477| / 23.490 x 100 = 0.055%
<span>Phytochemicals
Phytochemicals are biologically active however they are non-nutrient because they are not required. But they are active biologically active in that some can be used to protect cells from oxidative damage in the form of antioxidants.</span>
