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.

Which species in the food web would be subject to the greatest biomagnification of pesticides applied to the grasses
zaharov [31]

Answer:

<u><em>Hawk </em></u>

Explanation:

Biomagnification can be described as the accumulation of substances like toxins, pesticides etc in tolerant organisms. The biomagnification tends to increase as the trophic levels of a food chain increase. This is because these substances get more and more accumulated as they move up a food chain.

In the example of the food chain mentioned in this question, the highest trophic level is of hawks, so they will be subjected to the greatest biomagnification.
