Connor leaves his bicycle in the garage, but his brother Jordan leaves his bicycle outside. Connor notices that Jordan's bicycle chain is rusty, but his own chain is not.

Based on his observation, which is a hypothesis that Connor can test?

• If a bicycle is left outside, then its chain requires more grease than that of a bicycle left inside.

• If metal is exposed to air and moisture, then it will rust faster than metal kept in a closed, dry place because there is a chemical reaction.

• If rust forms on metal that is left outside, then bicycle chains should be made from a different material because there is a chemical reaction.

• If the chain on a bicycle left in a garage does not rust, then a garage is the best place to store bicycles.

Based on the image, what can you infer?

• Substances other than water may also cross the cell membrane.

• Substances other than water may block pores in the cell membrane.

• Water enters the cell when placed in environments of high water concentration.

• Water leaves the cell when placed in environments with a low concentration of solutes
