Answer: The correct answer is option c.
Explanation:
Cardiac conduction system is formed by specialized cardiac muscle cells which enable the heart to contract in coordinated fashion.
The main component of this system are:
- Sinoatrial node
- Atrioventricular node
- Bundle of His
- Branched bundle
- Punkinje fibers
SA node consists of cells known as pacemaker cells. These cells spontaneously generate action potentials which lead to the contraction of atria.
These potentials are then passed to AV node which relay them to bundle of His. These bundles are branched into right and left bundle which ultimately transfer these potentials to Purkinje fibers.
The potentials from these fibers lead to the contraction of ventricles.
I think the EAR is 7.79%
Since EAR = e^0.75 -1
= 7.79%

Answer:
The coral take in food from the water and provide shelter for the fish.
Explanation:
Coral reefs found in marine ecosystem and provide diverse ecosystem on the planet. They play very important role in marine ecosystem such as resist the effect of wave action and tropical storms and protect coastlines and provide shelter and habitat to other marine organism such as small fishes.
The image given shows fish and corals exists together and shows relationship between corals and fishes.<em> </em><em>This means, Corals take minerals and food from the water and provide shelter to marine animals. </em>
Like this corals functions in the marine system.
Hence, teh correct option is "The coral take in food from the water and provide shelter for the fish".
It is called subduction because it is going downwards and sideways.
