Heat from the sun makes it through near the Antarctic (where the hole is) is melting the ice and not allowing some key species to feed. seals don't have ice to come up for air through like normal so polar bears starve. loss of land means less food for a lot of species because the hunting grounds is closing and there is no room to expand.

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.
The answer would be A because if they are raised where every th ing is given to them they don't know how to do the normal functions they do naturally by themselves like hunt or maybe migrate.
