Antigens are surface proteins found on all cells including blood cells. In the case of blood groups, an individual's blood type reflects the presence or absence of specific antigens. An antigen-antibody response is initiated if the individual receives a transfusion of blood containing antigens that it identifies as being "foreign." Antibodies found in a person's blood bind to the foreign antigen, causing agglutination, or clumping. The antigen-antibody complexes clog the small blood vessels, and the foreign RBCs are lysed, releasing hemoglobin into the bloodstream. The most serious complication of a transfusion reaction is kidney failure due to blockage of the kidney tubules by the hemoglobin molecules.
Only about 70% of the energy that reaches Earth is absorbed, while the other 30% is reflected back into space.
Answer:
The current taxonomic system now has eight levels in its hierarchy, from lowest to highest, they are: species, genus, family, order, class, phylum, kingdom, domain.
Answer: Photosynthesis produces glucose cellular respiration uses glucose produced by photosynthesis.
Photosynthesis produces oxygen while cellular respiration uses oxygen produced by photosynthesis.
Photosynthesis uses carbon dioxide released in cellular respiration while cellular respiration produces carbon dioxide
Explanation: The products of photosynthesis are the reactants in cellular respiration while the products of cellular respiration are the reactants of photosynthesis. One reaction depends on the other to furnish it with the reactants. Photosynthesis depends on cellular respiration for the supply of carbon dioxide and water while cellular respiration depends on photosynthesis for the supply of oxygen and glucose. The balanced chemical equation for photosynthesis is 6CO2 + 6H2O+ sunlight --> C6H12O6 + 6O2
The balanced chemical for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy
