ANSWER: Administration of a blood transfusion

EXPLANATION:

Aplastic crisis is a potentially deadly complication of sickle cell disease that develops when erythrocyte production temporarily drops. Infection with parvovirus B-19 frequently causes aplastic crises (Saarinen et al., 1986).

Aplastic crisis may be associated with extensive bone marrow necrosis as well as acute selective erythroblastopenia

Immediate management is usually supportive involving mainly BLOOD TRANSFUSION to build up hematocrit level.

In the long term, bone marrow transplant to stimulate new cell growth is usually suggested.

preservation because he preserves part of the land and preserves means save

explanation:

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
