Answer:
False
Explanation:
The most specific feature of cardiac muscles is the presence of intercalated discs. Intercalated disc connects the ends of cardiac muscle fibers to one another. The discs have desmosomes and gap junctions. The function of desmosomes is to hold the cardiac fibers together. The gap junctions of cardiac fibers allow muscle action potentials to spread from one cardiac muscle fiber to another. These gap junctions have tubular connexons that form channels and connect the cytosol of adjacent cardiocytes to allow the flow of ions and spread of action potential from one cell to another.
Answer:
Adrenaline
Explanation:
The is the burst of energy caused by enzymes that send messages to the brain.Thus,resulting in Flight or Fight mechanism.
Enzymes are biological catalysts. Catalysts work by lowering the amount of energy required to set off a chemical reaction.
Only autotrophs can convert solar energy into chemical energy
