Heart muscles have long refractory period.
Explanation:
Heart muscle cells cannot rely on fermentation for long period of time because heart muscles have long refractory period which does not allow it to use the fermentation process. They have rich blood supply and have capillary density 4 times more than normal skeletal muscles. The anaerobic capacity is limited in the heart which does not allow the heart muscle cells to use fermentation process for metabolism. Our heart requires oxygen in large amount and very quickly for ATP production.

This is an example of co-evolution.
<u>Explanation:</u>
In co-evolution one species or a number of species evolve according to the changes in another species. Here the evolution of the beak of humming bird according to the shape of Ossifloramixta flower is an example of co-evolution. Co-evolution is common in the nature.
Bees, insects and butterflies commonly co evolve with the flower plants and vice versa. Co-evolution is of two types. The first type is specific co – evolution where only two parties are involved in co-evolution. In the second type of co-evolution namely diffused co-evolution many species evolve in response to specific traits in a species.
