Answer:
The correct answer is option C. "Most rocks from that era are deeply buried".
Explanation:
The Precambrian is the earliest era of Earth's history, predating the emergence of life during the Cambrian Period. Even tough it is the earliest era of Earth, the Precambrian era represents 88% of all geological time, which makes evident that life is relatively new in comparison to the Earth's total geological time. Most rocks from Precambrian era are deeply buried, result of diverse phenomena in the tectonic plates along history. This make most rocks inaccessible and prevents the finding of Precambrian fossils.
Amoxicillin is a broad-spectrum antibiotic widely used for certain
bacterial infections in the ear, nose, throat, genitourinary tract, skin, lower
respiratory tract, and its also used to treat gonnorhea. Amoxicillin is a
fairly strong drug, and it can elicit an allergy to patients even to those who
had used the drug before and did not experienced any untoward problems. If the patient
had symptoms such as difficulty in breathing, itching, and untoward swelling or
lump in the throat when receiving treatment with penicillins like amoxicillin,
sulbactam, ampicillin, methicillin, or penicillin G, the nurse should
discontinue giving amoxicillin and report to the doctor right away.
The correct answer is the<span> use of oil has the potential to affect aquatic viability during several stages. Offshore drilling practices to acquire oil for energy use can negatively impact aquatic viability through potential contamination and disruption of aquatic </span>habitats<span>. Transportation of oil over the water has the potential to contaminate aquatic </span>ecosystems<span> through oil spills. Waste products associated with the use of oil for energy production can also cause contamination of aquatic habitats.
