Answer:
Ebola; high mortality rate and high communicability.
Explanation:
Epidemology may be defined as the study the pattern, analysis and disease condition in the population. The risk factors of a particular disease can by done by the epidemology of the disease.
Ebola virus causes the fatal illness in the humans. Its generally affects the minimum individual and rare among the humans and the mortality rate is quite low. This virus can be transmitted from animals to the humans and then in the human population from humans to humans.
Thus, the correct answer is option (A).
Answer:
C) substitutions that reduce the affinity of hemoglobin for oxygen
Explanation:
Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.
The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.
