It is A: a chemical reaction, due to the acid activity (acetic acid)
B. They are determined by I, AB, A, or B
Answer:
i'd assume yes
Explanation:
If there was a picture it would help but im going off information i know aboutweathering and ersion.
Yes, physical wearthing did create this arch because waves they carry sedoment pieaces away or off of that rock and it possible could have been frozen off.

I really tried my best to help you and i hope this is the answer your teacher is looking for! Good luck and please make sure to word it in your own words :)
Answer:
A. Prions do not contain genetic information, which is affected by ionizing radiation.
B. Denaturants may affect the tertiary structure of prions.
C. Prions are proteins.
Explanation:
Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.
Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.
