The time it takes in milliseconds for the brain to transmit a signal to your skeletal muscles can be determined given the speed and distance. It was given that the signal travels at approximately 25 m/s while the distance between the brain and one' hand can be set to approximately 1 m. To obtain the time, we divide the distance by the speed and convert it to milliseconds.
The equation would be: (1 m/ 25 m/s)*(1000 ms/1 s) = 40 ms.
Thus, it will take 40 ms for the brain's signal to travel before it can command your skeletal muscles to react accordingly.

Answer:
(1): CONNECTIVE
(2): PLASMA
(3): INJURY
(4): 55%
(5): RED BLOOD CELLS
(6): WHITE BLOOD CELLS
(7): THROMBOCYTES
(8): ERYTHROCYTES
(9): LEUKOCYTES
(10): PLATELETS
Explanation:
In terms of its tissue classification, blood is classified as a ____CONNECTIVE______tissue because it’s extracellular matrix determines its function. Blood is composed of living blood cells, called formed substances, suspended in a nonliving fluid matrix called ___PLASMA________. The "fibers" of blood only become visible during ______INJURY____________. When blood is centrifuged, the plasma is less dense and rises to the top. It makes up ___55%_____ of whole blood. The other 45% is comprised of 3 formed elements, scientifically they are called: ____RED BLOOD CELLS_______ (RBC), _____WHITE BLOOD CELLS____ (WBC) and ____THROMBOCYTES_____(platelets). The heavier blood cells become packed at the bottom. Most of the bottom is composed of _____ERYTHROCYTES___________. The "buffy coat" separates these two areas. It is composed of ____LEUKOCYTES______ and ___PLATELETS_______.
