Skeletal muscle is controlled by the organism. which best describes what this means in terms of movement? a) any muscle attached to the skeleton is voluntary and may be used for movement. b) some of the muscle attached to the skeleton is involuntary and may be used for movement. c) some of the muscle attached to the skeleton is voluntary and may be used for movement. d) all of the muscles attached to the skeleton are involuntary and may be used for movement.

The correct answer is-

C) Some of the muscle attached to the skeleton is voluntary and may be used for movement.

Skeletal muscle primarily includes voluntary muscles that are generally attached to the skeleton.

Skeletal muscles help in moving body parts and can also contracted involuntarily by certain reflexes.

For instance, we can choose to move our legs, but we may start jumping automatically if our finger gets burn on a gas stove.

In this question, skeletal muscle is controlled by the organism.  This indicates that Some of the muscle attached to the skeleton is voluntary and may be used for movement.

Thus, option C) is the right answer.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
