Answer:
Most of us have some familiarity with everyday magnetic objects and recognize that there can be forces between them. We understand that magnets have two poles and that depending on the orientation of two magnets there can be attraction (opposite poles) or repulsion (similar poles). We recognize that there is some region extending around a magnet where this happens. The magnetic field describes this region.
There are two different ways that a magnetic field is typically illustrated:
The magnetic field is described mathematically as a vector field. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force. Arranging many small compasses in a grid pattern and placing the grid in a magnetic field illustrates this technique. The only difference here is that a compass doesn't indicate the strength of a field.

Answer:
endoplasmic reticulum (ER)
Explanation:
The endoplasmic reticulum (ER) is an organelle that helps make and transport proteins and lipids.
Answer:C the Cytoskeleton
Explanation: It is the Cytoskeleton because provides support to the cell. It is not the cell wall because that is for the plant cell, but the cell on the left is a eukaryotic animal cell. hope this helps (:(:):)
