The name of the structure labeled as A is 'myosin'. Moreover, the name of the structure labeled as B is 'actin'.
A sarcomere is the basic unit of muscle contraction. This unit is defined as the region between two Z-lines.
Band A is a central band composed of the thick filaments of myosin.
Moreover, the sarcomere also has two halves of a band known as I-band, which consists of thin filaments of actin.
Muscle contraction is caused by the interaction between actin and myosin protein filaments in the sarcomeres.

We would receive less energy than the corn contains because in a food chain there is always a loss of energy.
The statement 'Islands are often isolated, minimizing gene flow and maximizing diversification' explains why islands may have unique species on Earth.
<h3>What is isolation?</h3>
Isolation refers to the absence of gene flow between individuals of the same species for extended periods of time.
Isolation due to geographic barriers (e.g., a island) may led to reproductive differentiation and even to speciation.
In conclusion, the statement 'Islands are often isolated, minimizing gene flow and maximizing diversification' explains why islands may have unique species on Earth.
