The labeling of the cell represents.

The label B is Cytoplasm: This is the fluid part of the cell which has all the organelles floating in it.
The label C is ribosomes: It is the an organelle present in that that is responsible for the protein synthesis.

The two kinds of unbalanced forces are:
- Net Force: Is the vector sum of all forces acting (pushing or pulling) on an object.
- Resultant Force: is a force that alone produces the same acceleration as all those forces.
To effects that unbalanced forces have on objects are:
- Can make an object move or stop.
- Can speed up or slow down an object.
Here are some examples:
- When falling out of a plane when sky diving, this is making you move faster. Then when you are using a parachute, you are slowing down.
- A man uses force to roll down an object from the top of a hill.

Lymph nodes are part of the immune system. They release lymphocytes, a certain type of white blood cell that fights infection.
