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.

What happens to any matter that is not used by consumers in a food chain?
kramer
Matter that is not used by consumers in the food chain become "detritus". Detritus, meaning debris or waste, are materials that are missed or uneaten by consumers. Because they do not participate in higher trophic levels, these materials are left to decompose. Detritus is often considered the "missing mass" when measuring the total mass in the food chain.
