The commonality between the two changes is:

Both conserve mass

For the other options:

  • Rust forming on a metal gate is a chemical change because it involves a reaction with oxygen.
  • Snails growing shells is a biological process and is generally a physical change where the snail's body incorporates substances to build its shell.

So, "Both are only physical changes" and "Both are chemical changes" would not apply. "Both are changes in state" also doesn't apply, as neither change involves a state change (such as solid to liquid).

Therefore, the correct selection is Both conserve mass.

Select all that apply.

Based on your prompt, the applicable commonality between the two changes (rust forming on a metal gate and snails growing shells) would be:

  • Both conserve mass

None of the other options apply based on the nature of the changes:

  • Both are only physical changes - This is incorrect as rust formation is a chemical change.
  • Both are changes in state - This is incorrect as neither change involves a change in physical state (solid, liquid, gas).
  • Both are chemical changes - This is incorrect because snails growing shells is primarily a biological and physical process.

So, the only applicable option from your list is Both conserve mass.

theres more than one

Thank you for your patience. Given that we're looking for multiple applicable responses, let's reassess the options:

  1. Both are only physical changes - This is incorrect. Rust formation is a chemical change, whereas snails growing shells is primarily a physical process.

  2. Both conserve mass - This is correct. According to the law of conservation of mass, mass is conserved in both processes.

  3. Both are changes in state - This is incorrect as neither process involves a change of state (e.g., solid to liquid).

  4. Both are chemical changes - This is incorrect. As mentioned, rust formation is a chemical change, but snails growing shells is not strictly a chemical change.

Given a reevaluation, the only applicable response is Both conserve mass.

If you meant that there may be a broader context or interpretation that allows for more than one response, please clarify. Otherwise, "Both conserve mass" remains the key correct response here.
