Correct answers:
1) Scientists discovered that elements of blood could be separated by centrifuge.
2) New ways to preserve and transport blood for blood transfusions were discovered.
5) Blood transfusion safety was improved.
Brief reasons:
- Knowing blood groups made safe transfusions possible (matching donor and recipient), so transfusion safety improved.
- That knowledge spurred development of blood‑preservation and transport techniques (anticoagulants, stored blood, and later blood banks).
- It also led to separating blood into components (plasma, cells) using centrifugation so patients could receive just what they needed.
Why the others are wrong:
- “Plasma could be preserved by freezing” is not a direct, immediate result of the 1898/1900 blood‑group discovery (frozen plasma techniques came later).
- “Blood types had no significant impact” is false — the discovery was foundational for modern transfusion medicine.
