Answer
### Question 13
# Brief Explanations:
When rubbing a balloon on hair, electrons are transferred, giving the balloon a net charge. Opposite - charged objects attract. The electric force between the charged balloon and the neutral wall causes the balloon to stick. Gravity pulls objects downwards and is not responsible for this sticking. Friction is a force that resists motion between surfaces in contact and is not relevant here. Magnetic force acts between magnetic materials and is not involved in this scenario.
# Answer:
C. electric force
### Question 14
# Brief Explanations:
The cell - theory has three main points: all living organisms are made up of one or more cells, the cell is the basic unit of life, and all cells come from pre - existing cells. The organisms shown (snail, butterfly, slime mold, fungus, cactus) are all made of one or more cells. Not all of these organisms have cells that lack a nucleus (they are mostly eukaryotes with a nucleus). Only plants (like the cactus) among them can undergo photosynthesis. The cells of these organisms are not identical as they have different functions and structures.
# Answer:
B. The organisms are made of one or more cells
