C. how does hbs aggregation occur in sickle-cell anemia? place the steps in the correct order. note that deoxyhemoglobin is in the t state; oxyhemoglobin is in the r state.

Well I hope these steps are good:
1) First, the addiotional T state of the Hemoglobine Sinteract with the agregation that is growing to form a fiber that is insoluble.
2) Second, Val makes an interaction with a cell or pocket of a beta chain on another Hemoglonine S.
·3) Then the R state of the Hemoglobine changes into T state of Hemglobine and 
4) the oxigen (O2) decreases because of high altitude

When scientist examine data such as historical documents, they are using the "scientific methods"
