An experiment measures the growth of crystals in a liquid solution abroad the space shuttle a collection of bottles has the liquid in varying strength or concentration of this tested substance what she would be a control observation in this experiment

Explanation:

Protein crystals growth where first performed on space lab.

Experiment show that the liquid to liquid space grown system are larger than crystals obtained by same experiment on earth.

Crystallization in the microgravity experiment in space can be controlled and it will improve crystal quality by eliminating convection effects near growing crystal surfaces.

Diffraction in the microgravity experiment in space can also be controlled and it will also improve the quality attributed to better ordered crystal growth in microgravity.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
