Answer:
<em>Read explanation.</em>
Explanation:
Well, because it plays such an important role in problem solving. Science is all about solving the problems, puzzles and riddles of this world and universe, and to do that, we elaborated something called the scientific method.
The scientific method is a method we follow to encounter, solve and understand certain problems. A famous example would be the "broken torch example":
Torch doesn't work → is it the batteries? → we try replacing the batteries
↓
or is it the circuit?
↓
we have concluded that it is not the batteries
↓
we try finding the problem in the circuit
↓
etc.
As you can see, in the example, the 2 possible problems that would explain why the torch isn't working, are our 2 hypothesis.

In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. ... If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. ... When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Answer:
the hormone receptor is a heterotetramer composed of two subunits with 95 kDa and two subunits with 135 kDa
Explanation:
In this case, the heterotetramer is composed of two heterodimers, each composed of two subunits that held together by disulfide bonds. These heterodimers bind together through hydrophobic interactions in order to form a tetramer. The Sodium Dodecyl Sulfate (SDS) is a denaturing detergent that dissociates both heterodimers by interfering with hydrophobic interactions that hold heterodimers together. It is for that reason that only a single band of 230 kDa is observed (135 kDa + 95 kDa = 230 kDa). Moreover, 2-Mercaptoethanol breaks disulfide bonds, thereby separating the two subunits in the heterodimer. In consequence, after the use of this chemical compound (2-Mercaptoethanol), two different bands with 135 kDa and 95 kDa can be observed.
