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:
So we can get energy to perform our daily activities.
Explanation:
When we eat food it gives us chemical energy that we (humans) transfer into mechanical energy. That is why you need food.
density and specific gravity are properties used to help identify minerals. Density is a measure of the mass of a certain volume of the sample. Specific gravity is a unit less measure, and it is the ratio of the mass of a substance to the mass of an equal volume of water. density and specific gravity are properties used to help identify minerals.

I think its D living space speaking how islands are small and that have fruit,water,and sunlight because their just the characteristics of a island.
So your answer is D living space
<span>Evidence about ancient climates indicates that
</span>glacial ice once covered much of what is now India and Australia
There was once glacial where these countries are located now due to heat it all melts
so correct option is A
hope it helps
