Make four different test groups.
Test 1: Add 10mL of A to 10mL of B, and insert substance X into the reaction. Record the time.
Test 2: Add 10mL of A to 10mL of B, and insert substance Y into the reaction. Record the time.
Test 3: Add 10mL of A to 10mL of B, and insert substance Z into the reaction. Record the time.
Test 4: This is your control group. Only add 10mL of A to 10mL of B, then record the time for the reaction to occur.
The catalyst is which ever substance caused for the reaction time to speed up. I hope that this helped! Please leave brainliest!
The discovery of the Rhesus factor affected society by improving the success rate of blood transfusions. Prior to the Rhesus system being implemented, blood was typed according to the ABO system alone. This meant a significant number of blood transfusions failed due to immunogenic reactions to the rhesus factor leading to agglutination of blood.
