Cardiac muscle tissue is muscle tissue found in the heart. It is similar to skeletal muscle in that both are striated and organized into sarcomeres but cardiac muscle fibers are shorter and usually contain only one nucleus in the central region of the myocyte (muscle cell). Cardiac muscle fibers are rich in mitochondria and myoglobin, (ATP is produced primarily through aerobic metabolism), are extensively branched and are connected to one another by intercalated discs. An intercalated disc is a structure that enables the propagation of contraction among muscle cells: it allows the muscle cells to contract in a wave-like pattern.

What were the independent, dependent, and control variables in your investigation? Describe the variables for the simulation wit

Phantasy [73]

The experiment is not found here but dependent variables may include the growth rate of moths, whereas the independent variable may be the temperature and the control is water.

<h3>What is a dependent variable?</h3>

A dependent variable is the variable that is being modified by the conditions of the experiment (in the example, the growth is dependent on the temperature).

Moreover, a control variable is any condition that remains constant throughout the experiment (in this case, the amount of supplied water).

In conclusion, dependent variables is the growth rate, whereas the independent variable is the temperature and the control is water.
