Based on the clumping that was obtained when anti-D serum was dropped into John Doe's blood, John Doe's blood type is<u> Blood type D.</u>
<h3>What is blood typing?</h3>
Blood typing refers to the process by which blood is classified into types.
The process of typing blood involves reactions in which agglutination of blood occurs when a certain type of antiserum is dropped into the blood that contains a particular antigen such that an antibody-antigen pair is obtained.
The presence of certain antigens on the surface of blood helps to classify blood into types.
For example, when anti-A serum is added to a blood sample and agglutination occurs, the blood type could be either blood type A or blood type AB as these blood samples contain the A antigen on the surface of the red blood cells.
Similarly, when anti-D serum is added to a blood sample, the blood type is a blood group D as this blood sample contains the D antigen on the surface of the red blood cells.

Answer:
wind is produced by the uneven heating of the earth's surface by the sun
Explanation:
therefore, the sun is technically making windmills spin to make energy
Answer:
The process of photosynthesis is complex. Sunlight energy is converted into chemical energy by using chlorophyll, which is what gives plants their green color. Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose then releases the unused components such as oxygen.
Cations are positive so they have less electrons than protons, while anions are negative so they have more electrons.
