The duration of acute arthritis can range from a few weeks or months to years or even a lifetime. It can also be persistent. IA types include autoimmune and autoinflammatory illnesses. This suggests that the immune system, which is meant to fight off viruses and pathogens, becomes confused and attacks the body's cells and tissues. The doctor can suggest blood testing for C-reactive protein and erythrocyte sedimentation rate. These blood tests evaluate inflammatory markers or markers of inflammation.

Explain two effects that the study of genes could have on the future.
adoni [48]
1) determine the probability of individuals inheriting a disease
2) In the future, new genetic mutations will arise, and knowing to understand genetics would be important in helping analyze the problem/mutation in genetic recombination.
3) Genetics allows us to link diseases to one another (pedigrees) by analyzing if they are recessive, dominant, and/or autosomal, this allows us, as scientists to be able to identify and classify future diseases, and to determine their inheritance pattern, in the future.
