Solution

One of the statements in the given options is not true about cardiac muscles. Let's analyze each statement step by step:

  1. They can be controlled: This statement is true. Cardiac muscles are involuntary muscles, meaning they are not under conscious control.

  2. They lack mitochondria: This statement is not true. Cardiac muscles contain a high number of mitochondria, which are responsible for producing energy in the form of ATP.

  3. Cells are bi-nucleate: This statement is true. Unlike most other muscle cells, cardiac muscle cells have two nuclei.

  4. Found outside the heart such as the digestive tract: This statement is not true. Cardiac muscles are specifically found in the heart and are responsible for its contraction.

Based on the analysis, the statement that is not true about cardiac muscles is: They lack mitochondria.
