The answer to this question is evaporation
Answer: option A - denature
Explanation:
Microbial control agents are KNOWN to DENATURE cell proteins as a step in pathology of many diseases.
And because PROTEINS ACTIVITY depends on their three dimensional configuration, microbe attack and BREAK the bond in order to penetrate the cell membrane.
So, the ONLY right option is A
The levels of protein structure that are most affected by chemically straightening the complex of protein that makes hair would be the quaternary and tertiary levels. This is because in this process, one would be disrupting many of the interactions that would be occurring between the R groups of the protein, including hydrogen bonding and other van der waals forces.
These interactions can affect more than 1 polypeptide chain as well and thus the quaternary is also affected.
Hair will not remain straight as after the reagent or other substance is removed the hydrogen bonds will again reform and the R groups will orient themselves to maximize interactions.
Commonly prescribed antibiotics are becoming less effective due to a number of reasons:
-overuse of antibiotics
-failing to complete the fully prescribed course by a doctor
-use of antibiotics in farming
These can lead to the effectiveness of antibiotics being reduced, and the incidence of antibiotic resistance increasing. These bacteria are commonly known as superbugs.
