What is an independent variable?
Alexus [3.1K]
The <em>independent </em>variable is the variable that you change and control in your experiment. The <em>dependent</em> variable is the one you don't have control over and is affected by how the independent variable reacts.

For Example:
Let's say you're doing an experiment seeing how different sugars affect the density of cupcakes. The type of sugar you add would be the independent variable, because you are choosing it. The density would be the dependent variable, since it depends on the sugar used.

The triad in a skeletal muscle fiber is composed of a centrally located T-tubule flanked on both sides by the terminal cisternae
katrin [286]

Answer

Option B. This mutation will increase the sensitivity of the DPH receptor to voltage changes, which will induce continued muscle contraction.

Explanation:

Since the receptor stays open, it allows for calcium to be released from the sarcoplasmic reticulum and thus, enables muscle contraction to take place.

Hope that answers the question, have a great day!
