Microtubules, microfilaments, and intermediate filaments make up the which lies beneath the plasma membrane and provides support, movement, and shape for the cell.
a) cell wall
b) cytoplasm
c) cytoskeleton
d) golgi complex

Option C, Cytoskeleton

Explanation:

Cytoskeleton is made up of following structure -

a) Microtubules - it is the largest part and help in organelle transport

b) Actin filaments

c) Intermediate filaments

d) and several proteins to support this system

These three components give shape to the cell and also keep all the internal parts of the cell intact.

They also support cell in movement

Cytoskeleton play a supportive role in cell division as well

Hence, option C is correct

yes? sounds right, but you didn’t ask a question.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
