Hair proteins (peptides) are first treated with a sulfhydryl reducing agent to break disulfide bonds and thereby destroy much of the natural tertiary structure and shape of the hair. After being set in the desired shape, the hair is treated with an amide oxidizing agent to allow the disulfide bonds to re-form between different cysteine groups, as determined by the positioning imposed by the curlers.

The remote sensing technique known as _________ has enabled scientists to map more than 800 square miles (2,100 square kilometer
allsm [11]

From what we know, we can confirm that the remote sensing technique described in the question is that of laser scanning.

<h3>What is laser scanning?</h3>

This is, as described in the question, a remote sensing technique. This is a method most often used for land surveys, in which lasers are pointed at the area, which gather information in the form of 3D coordinates, which are later compiled to create detailed maps of the region.

Therefore, we can confirm that the remote sensing technique used by the PACUNAM project in order to map more than 800 square miles of the Maya Biosphere Reserve in Guatemala, is that of laser scanning.

You continually lose energy as you work your way up an ecosystem, so normally there are only three or four levels. I hope this helps!
