You are a crime scene investigator analyzing a crime scene. Your victim has type A blood and your suspect has Type B blood. You analyze a blood sample found at the crime scene and identify anti-A antibodies and B antigens. Whose blood is it

the blood belongs to my suspect who has type B blood.

Explanation:

In 1900, Karl Landsteiner convincingly demonstrated that there were individual differences between the plasma membrane of the red cells of normal individuals. These differences has been a useful tool in the field of forensic science.

Landsteiner showed the presence of one of two antigens ( either A or B or neither, which was later called O) on the red cells of each individual. He also discovered that the serum from such individuals contained different antibodies. Example:

Blood group A contained antibody B

Blood group B contained antibody A

Blood group O contained antibody A and antibody B.

Blood group AB contained no antibody.

From the above discovery by Landsteiner, the blood analysed from the crime scene belongs to my suspect who has type B blood.

explanation:

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
