The given blank can be filled with a feature resulting from hot volcanic rock.
The geysers refer to the rare characteristics on Earth, only about 1000 of them prevail, and more than half of those are situated in Yellowstone. For a geyser to develop, there must be a source of volcanic heat, enough groundwater, and a geologic plumbing system via which the heated water can escape.
The absconding of water takes place when the groundwater is heated by the hot volcanic rocks. The intensifying steam bubbles push the water above via the fissures in the rock until they overflow from the geyser.
With the absconding of the top layers of the water, the pressure on the hotter waters below diminishes, leading to a violent chain reaction of explosions, which expand the volume of the rising boiling water by up to 1500 times or more.
If you don’t, you’ll either pass out or die.
The reason that might cause a reaction that originally proceeds through the path of X to change and proceed through the path Y is the addition of a catalyst.
<h3>What is a catalyst?</h3>
A catalyst is a substance that provides an alternative path for reaction. This implies that the energy tat s required to surmount the energy hump as the reactants are converted into products have been reduced. This can be seen in the fact that the energy hump between the reactants and the products in Y is lower than that in X
Thus, we could say that the reason that might cause a reaction that originally proceeds through the path of X to change and proceed through the path Y is the addition of a catalyst. The catalyst lowers the activation energy of the reaction.

For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.
Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-
1. Denaturation of the double-stranded DNA (at around 95°C)
2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)
3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).
With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.

Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
