Answer:
Explanation:
In the Hershey and Chase experiment, they aimed to show where the phage DNA went when it exited the protein coat and entered the bacteria. In this scenario, the two student's approach won't work because amino acids (and therefore all proteins) also have nitrogen atoms which ultimately means that the radioactivity would not distinguish between DNA and proteins and the experiment will not provide the correct results.
Answer:
The correct answer is "excretes; hypotonic; absorbs, hypertonic".
Explanation:
Cell's homeostasis is only conserved in an isotonic solution, since cells that are in an hypertonic solution (high salt concentration) tend to loss water, and in hypotonic solution (low salt concentration) tend to absorb water. Brine shrimp lives in waters that are both, hypertonic and hypotonic and has adapted to overcome this issue by excreting and absorbing salt across its gills. In very high salt concentrations, a brine shrimp "excretes" salt across its gills and maintains an internal salt concentration that is "hypotonic" relative to the water where it lives. In lower salt concentrations, a brine shrimp "absorbs" salt water across its gills and maintains an internal salt concentration that is "hypertonic" relative to the water where it lives.
