Question

Climate change is melting the Earth's permafrost, which contains carcasses of old organisms (humans and animals alike). Organisms that died decades ago due to smallpox are thawing, and these viruses are re-entering the ecosystem in freshwater sources and to organisms grazing nearby. Smallpox epidemics in the coldest parts of the world are happening. Although there is an effective smallpox vaccine, most people are not vaccinated because it has been eradicated since 1977, which is the major concern for new exposures. Contracting the disease leads to the development of skin sores all over the body and potential blindness. If a patient survives, they will lead a healthy life with the only signs of the disease being skin scarring. With this information, answer the following questions: Is this an enveloped or non-enveloped virus? Identify the evidence from the passage for this and explain why this evidence supports your conclusion. Is this a DNA or an RNA virus? Identify the evidence from the passage for this and explain why this evidence supports your conclusion. Does this virus undergo lysogenic or lytic growth? Identify the evidence from the passage for this and explain why this evidence supports your conclusion.
