I am having trouble with something in the category of Biomolecules. The question states:
Describe the basic molecular structures and primary functions of the four major categories of biological macromolecules; including their molecular structures, their monomers (building blocks), and their basic function in living organisms.

If someone could please help me id greatly appreciate it. :)

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.

the answer is c because it is most logical.
