Im not sure but if you think of it, the one that you didn't put any salt is a independent variable because it doesn't really rely on anything it doesn't have salt. The Dependent variable would be the 2nd and the 3rd cup because it doesn't have much salt but the 4th cup has lots of salt so its basically controlled. Hope it helps !
Homeostasis is maintained by the respiratory system in two ways: gas exchange and regulation of blood pH. Gas exchange is performed by the lungs by eliminating carbon dioxide, a waste product given off by cellular respiration.
Answer:
A. Helicases
B. Single strand binding proteins
C. Single strand binding protein
D. Topoisomerases
Explanation:
The helicases bind on the replication fork aiding in the unwounding of the DNA helix to allow for replication. The single strange binding proteins attach/bind to the separated single stranded DNA after the replication fork to prevent re-annealing of the single stranded DNA preventing Hydrogen bond formation that reanneals these two strands together. The topoisomerases are found just ahead of the replication fork preventing overwounding/ positive supercoils of the DNA. They do this by introducing breaks into the phosphate backbone of the DNA allowing them rotate forming negative supercoils and attaching the breaks once the DNA strand is relaxed.
The animals can't adapt to the change. This causes them suffer and die outside of their natural zone. It can cause them to go extinct if left this way.
Answer:
The most well-known Hershey-Chase experiment was the final experiment, also called the Waring Blender experiment, through which Hershey and Chase showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages
