Answer: Blood group O individuals are able to produce Anti- A and Anti- B and are often referred to as UNIVERSAL DONORS, while blood group AB individuals produces none and are often referred to as UNIVERSAL RECIPIENTS
Explanation:
Two antigens, type A and type B, occur on the surfaces of the red blood cells in a large proportion of human beings. These antigens are referred to as agglutinogens because they often cause blood cell agglutination during blood transfusion. Because of the way these antigens are inherited, people may have neither of them on their cells , they may have one or they may have both simultaneously.
When type A antigen and type B antigen is not present in an individuals reb blood cell as seen in blood group O, antibodies known as Anti-A and Anti- B develops in the plasma. This is because small amounts of type A and type B antigens enter the body through food, bacteria and other ways and they initiate the development of anti A and Anti- B antibodies in their plasma.
Furthermore, individuals with blood type AB has antigen A and B on their red blood cells and therefore do not develop antibodies A and B in their plasma. This makes them universal recipient as their blood do not discriminate any ABO blood group during blood transfusion.
Answer:
Mitochondria differ from chloroplasts in that mitochondria is the energy bank of every cell while chloroplast houses the chlorophyl that gives green pigmentation for photosynthesis to occur in plants
Explanation:
The meter is the basic measurement unit for length. It has submultiples (centimeter, milimeter, micrometer) and multiples (kilometer).
100 cm = 1 m
1000 mm = 1 m
1000000 micrometers = 1 m
1000 m = 1 km
