Answer:
A) The striations are due to the orderly arrangement of actin and myosin
Explanation:
Smooth muscles are non-striated involuntary muscles which are found in the walls of stomach, urinary bladder, blood vessels...Smooth muscle tissue is composed of spindle-shaped muscle cells with single central nucleus. Like the other two type of muscles (cardiac and skeletal), smooth muscles also have four main functions:
- Contractility-ability to contract. In the case of skeletal muscles it is voluntary, while in cardiac and smooth muscles it is unconscious.
- Excitability-ability to change membrane potential usually by the influence of nervous impulse.
- Extensibility-the capacity to lengthen
- Elasticity-ability to change its length and then return to previous.

Explanation:
Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth's rotation results in the Coriolis effect which also influences ocean currents.

Answer:
The electrostatic force is also known as the Coulomb force or Coulomb interaction. It's the attractive or repulsive force between two electrically charged objects. Like charges repel each other while unlike charges attract each other. Coulomb's law is used to calculate the strength of the force between two charges
