Answer:
Explanation:
Antimicrobials are probably one of the most successful forms of chemotherapy in the history of medicine. It is not necessary to reiterate here how many lives they have saved and how significantly they have contributed to the control of infectious diseases that were the leading causes of human morbidity and mortality for most of human existence. Contrary to the common belief that the exposure to antibiotics is confined to the modern “antibiotic era,” research has revealed that this is not the case. The traces of tetracycline, for example, have been found in human skeletal remains from ancient Sudanese Nubia dating back to 350–550 CE (Bassett et al., 1980; Nelson et al., 2010). The distribution of tetracycline in bones is only explicable after exposure to tetracycline-containing materials in the diet of these ancient people. Another example of ancient antibiotic exposure is from a histological study of samples taken from the femoral midshafts of the late Roman period skeletons from the Dakhleh Oasis, Egypt (Cook et al., 1989). These samples showed discrete fluorochrome labeling consistent with the presence of tetracycline in the diet at that time (Cook et al., 1989). The postulated intake of tetracycline in these populations possibly had a protective effect because the rate of infectious diseases documented in the Sudanese Nubian population was low, and no traces of bone infection were detected in the samples from the Dakhleh Oasis (Armelagos, 1969; Cook et al., 1989).
Answer: A. Animals May Suddenly Appear Without Warning
Explanation:
Even Though All Are Valid, The Most Likely To Be Associated With Hazardous Accidents, Would Be A, Because Traction Usually Happens If In Snow, Or On Road And Turning It Off, Usually It is On For Safety And Is Mostly Kept On At All Times. For B, They Can Create Confusion, But Only In Large Areas, If You Were In A More Open Areas, Just Like A Rural Area, Then Its Most Likely Not As Hazardous. And For A, It Is Most Likely That You Must Be Cautions Because In Open Areas There Is More Of A Chance To Find Animals In Sight.
The answer is a. Hope this helps.(:
I wish you the best of luck!
