Answer:
Water will move into the beaker.
Explanation:
Only water can move between the bags. The water and the NaCl naturally want to reach equilibrium, so since the side with 80% NaCl is more concentrated, the water will move there to make it less concentrated. Both inside the back and in the beaker will reach 75% NaCl.
Many medicines such as digitalis and quinine come from plant products. Drugs derived from plants have been in use to treat illnesses and various medical conditions for thousands of years. Digitalis, which is used to treat heart diseases was derived from foxglove plant while quinine which is use for treatment of malaria was derived from the bark of a peruvian tree, the Cinchona.
Answer:
it is expected to observe two bands: one band of light density and one band of heavy density
Explanation:
DNA replication is semiconservative because when DNA is replicated both resulting DNA molecules are composed of one original strand and one newly synthesized strand. If DNA replication would be conservative, then the original DNA molecule would serve as a template to produce a new DNA molecule, thereby each cell division would produce one daughter cell with a new DNA molecule and one daughter cell with the original DNA molecule of the parental cell. In this case, the transfer of bacteria-like organisms into a heavy 15N medium would produce two types of DNA cells after replication: cells with original DNA of light density (14N) and cells with new DNA of heavy density (15N), which would be distributed in two bands after centrifugation.
