Answer:
The evidence from the eruption helps scientists study past climate changes and compare them to modern changes.
Explanation:
Essentially, they like to study an area of difference so that they can see what changes in that situation; and they are able to understand <em>what </em> would change in a study sample (letting them know what measures to look for)
90% of people weigh more than Nikoleta and 10% weigh less.
The nitrogenous bases placed in between the DNA double helix strands, like rungs on a ladder, are positioned there because of the hydrophobic effect and are stabilized by hydrogen bonding. The stability of DNA also relies on the interactions between the hydrogen bonds between bases, hydrogen bonds between bases and surrounding water, and base interaction between neighboring bases.
Hydrogen bonds are able to stabilize the DNA double helix by pairing up with their complementary base pairs (guanine with cytosine and adenine with thymine)
