Answer:
Paper
Explanation:
In chromatographic separation, two different phases are important; a stationary phase and a mobile phase.
The stationary phase is the phase that does not move. Substances are separated based on how fast or slowly they move in the stationary phase.
The mobile phase is usually the solvent(or mixture of solvents) that carries the solutes through the stationary phase.
The stationary phase is usually composed of a porous material. Paper is a porous material. The mobile phase is trapped between the cellulose fibers of the paper and separation is achieved.

Answer: 598.9K = 325.9°C
Explanation:
P1= 53.3kPa T1= -33+273=240K
P2=133kPa , T2= ?
Applying P1/T1 = P2/T2
Substitute and Simplify
53.3/240 = 133/T2
T2= 598.9K = 325.9°C
The two strands must be separated like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases.
<u>Explanation:</u>
- A double helix structure formed by two polypeptide chains is separated like the two sides of a zipper. A zipper is formed by breaking the weak hydrogen bonds that link the paired bases. During replication, an enzyme "Helicase" travels down the DNA and splits the chain and it forms 2 separate strands.
- The two DNA strand which has the same sequence must be separated like the two sides of a zipper by breaking weak hydrogen bases. During base pair-rule, the strand are unzipped and each strands is copied.
