Multiple Choice

The football coach at State University wishes to determine if there is a change in offensive production between the first half and the second half of his team's recent games. The table below shows the first-half and second-half offensive production (measured in total yards gained per half) for the past six games.
$\begin{array}{lcccccc}\hline & {\text { Game }} \\& 1 & 2 & 3 & 4 & 5 & 6 \\\text { First half yards } & 123 & 136 & 130 & 134 & 95 & 93 \\\text { Second half yards } & 103 & 120 & 116 & 143 & 62 & 60 \\\hline\end{array}$

A reversal in the electrical potential across a cell's plasma membrane, leading to the initiation of an action potential or nerve impulse.

Sodium Ions

Positively charged atoms of sodium, crucial for maintaining fluid balance and transmitting nerve impulses in the body.

Potassium Ions

Electrolytes with a positive charge found inside and outside of cells, essential for maintaining normal cell function including nerve impulse transmission and muscle contraction.

Excitation-Contraction Coupling

Stimulation of a muscle fiber produces an action potential that results in contraction of the muscle fiber.
