The correct Answer is:
To solve the question "Removal of calcium from freshly collected blood would:", we can follow these steps: ### Step 1: Understand the Role of Calcium in Blood Clotting Calcium ions (Ca²⁺) play a crucial role in the blood clotting process. They are essential for the activation of various clotting factors and the conversion of prothrombin to thrombin, which is a key step in the formation of a blood clot. ### Step 2: Analyze the Effects of Calcium Removal When calcium is removed from freshly collected blood, the necessary ions required for the clotting cascade are no longer present. This means that the processes that lead to clot formation cannot occur. ### Step 3: Identify the Correct Outcome Given that calcium is vital for clotting, its removal would lead to the prevention of clot formation. Therefore, the correct outcome of removing calcium from blood is that it would prevent clotting. ### Step 4: Select the Correct Answer Based on the analysis, the correct answer to the question is: "Removal of calcium from freshly collected blood would prevent clotting." ### Final Answer The correct answer is: **Prevent clotting.** ---
