There has to be one side with a high concentration and another side with a lower concentration
Answer:
The most appropriate answer would be option B.
The flaw in their reasoning is that they compared different molecules in a different set of organisms.
For example, they compared the DNA of lizard A and B whereas they compared the RNA of lizard B and C.
In addition, the mutation rates of different molecules (DNA and RNA) are different and thus, comparison of DNA in one set of organism and comparison of RNA in another set cannot be used as the basis for the conclusion.
Different people are affected by COVID-19 in various ways. The symptoms experienced by infected individuals have ranged widely, from little discomfort to serious sickness.
- The susceptibility to and prognosis of severe acute respiratory syndrome caused by coronavirus 2 or coronavirus disease 2019 (COVID-19) have been found to vary greatly amongst individuals and populations.
- Intervention in public health must take into account these variations and how they affect susceptibility to infection and the severity of disease.
- The distinctions between the COVID-19 case profiles from China and North America may be due to regional variations in host, environmental, and healthcare-related factors.
- These inter-population variances, together with intra-population variability, highlight the need to identify how health inequities and inequalities affect the public health response to COVID-19 and can help with preparing for the epidemic's resurgence.
