Which feature creates the striated appearance of skeletal muscles?

Repeated bands of Actin and Myosin give the striated appearance to the skeletal muscles.

Explanation:

Skeletal muscles connect to bones or skin and provide aid to the movement and locomotion which can be voluntarily controlled. These muscles fibers are long and cylindrical. Their striated appearance can be seen under the microscope. Such type of appearance is due to the Actin and Myosin which are contractile proteins and are arranged at regular intervals in the skeletal muscle fiber. Actin, a globular contractile protein interacts with Myosin and the muscle contraction process is facilitated.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
