Explanation:
Gravity, magnetism, and electricity all use fields to act on objects without actually touching them. They can all force objects to move without touching them through these fields.
That is meiosis because it is splitting
Answer:
Because it forms beta arrangements subsecuently forming microfibrils
Explanation:
Cellulose is a complex carbohydrate formed by a long polysaccharide of glucose molecules with <em>beta arrangements, these give a flat and rigid structure that held to each other through hydrogen bonds forming microfibrils that give their rigidity to the cell walls</em> (you can see this structure in the image added).
