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. It also helped prenatal care as people became aware of the possibility of the mother and child being Rhesus incompatible. This condition could be combated by an injection of antibodies.
Answer:
Cell Membrane
Explanation:
The unique structure of the cell membrane allows small substances (like oxygen or carbon dioxide) to easily pass through.
A catalyst increases the rate of reaction by decreasing the activation
energy. The correct answer is D. Catalysts are those substances that are
used in reactions to speed up the process. An example of a catalyst
might be iron, during the manufacture of ammonia within the Haber
process.
Answer:
C
Explanation:
Add radio labeled actin sub units to a mixture of actin filaments in which conditions are favorable for polymerization. This would enable you to identify the plus end of actin filaments.
Actin filaments are linear polymer of globular actin sub units Actin filaments have polarity. This means that the two ends can be identified due to structural differences.
D) layers with similar fossils
