Distinguish between voluntary and involuntary actions.
ANSWER:
DEFINITIONS_____________________________________VOLUNTARY MUSCLES:Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.
__________________________________________________INVOLUNTARY MUSCLES:the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.
_____________________________________DIFFERENCES1) VOLUNTARY MUSCLES are under our control but INVOLUNTARY MUSCLES are not under our control
2) VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles
3) VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.
4) VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.
5) VOLUNTARY MSUCLES require more energy. INVOLUNTARY MUSCLES require less energy.

What is cytoplasm?
The cytoplasm is a liquid that is filled inside the cell. Between the cell membrane and the nucleus, there is a jelly-like fluid called cytoplasm. It facilitates material exchange and storage among cell organelles.
Cytoplasm helps the cell to stay still and rigid. It places all the cell organelle into a fixed place and the transfer of ions and molecules is also done by the cytoplasm. It is made up of water, salts, and other various material.
They help in the coming in of the materials and going out of the materials. They also protect the cell from shock and other invasive, they make the cell rigid and flexible and also protect recall from each other.

They are the "geosphere" (land), "hydrosphere" (water), "biosphere" (life) and "atmosphere," specifically (air).
The biosphere, geosphere, hydrosphere, and atmosphere are the spheres. Together, they are in charge of establishing and preserving the Earth's climate, geological processes, and life.
The main significance of the hydrosphere is that it supports a variety of life forms, is crucial to ecosystems, and regulates the atmosphere. All of the water on the Earth's surface is covered by the hydrosphere.
Thus, the correct option is B.
