If the cell acquires X from its surroundings, X must cross the cell membrane by means ofA.exocytosis.B.active transport.C.receptor proteins.D.second messengers.. A cell begins to swell when it is placed in an unknown solution. What can you conclude about the solution?A.The solution is isotonic.B.The solution is hypotonic.C.The solution is saturated.D.The solution is hypertonic.Which proteins transmit information into a cell by binding to signal molecules?A.end proteinsB.marker proteinsC.channel proteinsD.receptor proteins
- A: Question 1) B. Active transport, the cell must actively concentrate the material X against a concentration gradient.Question 2) B. The solution is hypotonic. The concentration of solutes is higher inside of the cell and so water from the outside enters the cell causing it to swell.Question 3) D. receptor proteins. Cell surface receptors bind to extracellular ligand molecules and then signal into the cell's interior.

- Q: The question comes from a lab called 'Using Gel Electrophoresis to Separate DNA Molecules'.
- A: Well the "markers" are fragments of a known size. You load them at the same time and run them side by side with your samples. By using the "known" size bands in the marker lane, you can estimate the size of the fragments in the sample(s) you're running.
