Which of the following statements concerning homeostasis is false? A regulated variable is one for which a sensor exists within the system and that is kept within a limited range by positive feedback mechanisms. Variables that can be changed by the body, but for which sensors do not exist, are non-regulated or controlled variables. The response of effectors can result in changes in non-regulated variables, which, in turn, alter the regulated variable. Sensors, which detect the regulated variable and respond by transducing that stimulus into a different signal, are constantly active, even when the regulated variable is outside of the normal range. An error detector compares the signal being transmitted by the sensor (representing the actual value of the regulated variable) with the set point.

Question
Which of the following statements concerning homeostasis is false?
A regulated variable is one for which a sensor exists within the system and that is
kept within a limited range by positive feedback mechanisms.
Variables that can be changed by the body, but for which sensors do not exist, are
non-regulated or controlled variables.
The response of effectors can result in changes in non-regulated variables, which, in
turn, alter the regulated variable.
Sensors, which detect the regulated variable and respond by transducing that
stimulus into a different signal, are constantly active, even when the regulated
variable is outside of the normal range.
An error detector compares the signal being transmitted by the sensor (representing
the actual value of the regulated variable) with the set point.

The mechanism of contraction in smooth muscle is different from skeletal muscle in that
the site of calcium binding differs
ATP energizes the sliding process
actin and myosin interact by the sliding filament mechanism
the trigger for contraction is a rise in intracellular calcium
the thick filaments have fewer myosin heads
