When a uniform becomes saturated with blood, what is the proper action that should be taken before an athlete can return to competition? select only one?

The uniform should be changed immediately 

Blood is dangerous as it could carry pathogens from infected people. It is best to change the uniform immediately with a new one. The blood stain could be removed if you rinse the uniform but the pathogen might still there.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
