question 16

Multiple Choice

Solve the system. If there is no solution or if the system's equations are dependent, so state.
- $$\left\{ \begin{array} { l } x + y + z = 5 \\x - y + 5 z = 3 \\4 x + y + z = - 1\end{array} \right.$$

• A) infinitely many solutions; dependent equations
• B) \(\{ ( - 2,5,2 ) \}\)
• C) no solution or \(\varnothing\)
• D) \(\{ ( 2,5 , - 2 ) \}\)

Definitions:

Repolarization Phase

The process during which cells return to their resting negative charge following depolarization.

H Zone

The region within a striated muscle fiber's sarcomere that contains only thick filaments and diminishes during muscle contraction.

Myosin Myofilaments

Filamentous proteins in muscle cells responsible for contraction by interacting with actin.

Actin Myofilaments

Protein filaments that, along with myosin, play a key role in the contraction of muscle cells by forming the thin filaments in the structure of muscle fibers.
