Immediately following the arrival of the stimulus at a skeletal muscle cell, there is a short period called the latent period during which the events of excitation-contraction coupling occur.
This process is a connection between transduction in the sarcolemma and the initiation of muscle contraction. Sarcolemma is nothing but the cell membrane of skeletal muscle.
A single muscle twitch has a latent period, a contraction phase when tension increases and a relaxation phase when tension decreases.
The period of incubation, the interval preceding exposure to a pathogen toxin or radiation, and when effects occur. Muscle contracting, the time between a nerve stimulus and muscle contraction.

<u>Answer:</u>
<em>Construction of a railroad route is a strenuous task and one has to face several obstacles.
</em>
<u>Explanation:</u>
Setting up the best possible plan for laying a rail route is a time-taking task. Several factors like economical nature of the plan, proper availability of building materials, minimum river crossings etc should be considered.
To build a railroad route the government has to get hold of the land through which the railroad route is planned. This is never an easy task. The people of the area have to be given adequate compensation and should be properly evacuated. The chances of people disapproving the plan are more.
Gain in decibels is given by;
Gain db = 10*log (Po/Pi), where Po = Power output, Pin = Power input
Substituting;
Gain in db = 10 * log (50/5) = 10 db
<span>Force F = 280 N
Angle with the ground = 40 degrees
Weight of the Lawnmower = 350 N
Velocity is constant so Acceleration is 0
So Forward force Ff = F cos theta = 280 cos40
Frictional force with resists to back Fb = (u x Force from pressure) + vertical component of Force, where u is the coefficient of friction.
Fb = (u x m x g) + (u x 280sin40)
AS Ff = Fb => 280 cos40 = u x ((m x g) + 280sin40)
u = 280 cos40 / ((350 x 9.81) + 280sin40) = 214.49 / () = 0.405
So the coefficient of friction u = 0.405</span>
Answer:
B i think is the answer
Explanation:
i feel like it is B because if you put them together and the answer is 1.5 so it is B
