Answer:
(1)They are usually multi-nucleated.
Explanation:
Cardiac muscles are one of the three muscles found in the human body (the other two being skeletal and smooth muscles). It is the only type of muscle found in the heart. Cardiac muscle cells have a single nucleus unlike the skeletal muscle cells.
They possess many large mitochondria in their cell, which enable them actively carry out the process of aerobic respiration. The cardiac muscles contains an enormous amount of myoglobin pigment, which enable them store and transport oxygen. Due to the high glucose in its cell, excess glucose is readily stored as Glycogen, making it rich in glucose.
Based on the explanation, being MULTI-NUCLEATED is not a feature of cardiac muscle fibers.
Vacuoles are essential in plants because the plants need a place to store water, and be able to keep their upright shape. In animals, we have muscles and bones to keep us upright, and plants have vacuoles. Hope this helps!
When it comes to sensing physical and emotional pain, our brains use the same two areas: the anterior insula, a small patch of neural real estate that’s part of the cerebral cortex behind each ear, and the anterior cingulate cortex, a hook-shaped piece of brain tissue towards the front of the brain.
