Answer the following question given this paragraph: Exocytosis The reverse process of moving material into a cell is the process of exocytosis. Exocytosis is the opposite of the processes discussed above in that its purpose is to expel material from the cell into the extracellular fluid. Waste material is enveloped in a membrane and fuses with the interior of the plasma membrane. This fusion opens the membranous envelope on. Q: The reverse process of moving material into a cell is the process of what? A:
OPTIONS:
- endocytosis
- proteolysis
- osmosis
- exocytosis
exocytosis

Answer the following question given this paragraph: When a solid substance is involved in a chemical reaction, only the matter at the surface of the solid is exposed to other reactants. If a solid has more surface area, more of it is exposed and able to react. Therefore, increasing the surface area of solid reactants increases the reaction rate. For example, crushing a solid into a powder exposes more of the substance to other reactants. This may greatly speed up the reaction. You can see another example in Figure below . Iron rusts when it combines with oxygen in the air. The iron hammer head and iron nails will both rust eventually. Which will rust faster?. Q: When a solid substance is involved in a chemical reaction, only the matter from which part of the solid is exposed to other reactants? A:
OPTIONS:
- the top
- the base
- the interior
- the surface
the surface
