It took BP 87 days to stop the flow of oil they monitor it for 48 hours to make sure it was going to hold
It is called a homogeneous mixture
It will rise first in Japan and set in American Samoa
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)
Hope this was able to help you! I went through my answer and bolded the more important parts, and parts more useful for answering the question.
Those are both examples of ecological services!
