1. Teresa is a 4-month old girl who suffers from acute heart failure. She urgently needs a cadaver heart to carry out a heart transplant or her life will be in danger. Teresa has type O blood. A mother would like to donate the heart of her 16-year old daughter, who just died in a serious car accident. Her daughter also has type O blood. However, she is not qualified as a heart donor for Teresa. Fortunately, a donor of type AB blood is found one week later, and the heart transplant is done successfully with no signs of serious graft rejection. (a) Apart from blood group testing, describe the procedure of an additional test that should be done to reduce the chance of graft rejection. (b) Give three possible reasons to explain why the 16-year old girl is not a suitable heart donor for Teresa, despite they both have the same blood type. (c) Explain why a donor with any blood type (e.g. type AB blood in this case) can be considered acceptable for Teresa. (d) Name one class of drug that should be given to Teresa after the heart transplant. Briefly explain its mechanism of action.

Bacterial Morphology
The bacteria are prokaryotic organisms that are single-celled, and are found to exist as free-living and possess a microscopic size. The morphology is found to vary in the bacteria, where some of them are identified as individual organisms and the others are detected as colonies. The size and shape of the bacterial cell also represent its morphology.
Bacterial cell structure
Bacteria are single-celled, tiny creatures that may enter healthy tissues and grow rapidly. Bacteria are microscopic organisms that are tiny and unicellular. These are members of the prokaryote kingdom. They live in water, air, soil, and all-natural environments. They are used in industrial and therapeutic processes, and they support a wide range of plant and animal life. The first organism to appear on the planet. Bacteria-like creatures are the oldest known fossils. Bacteria can consume a wide range of organic and inorganic elements, and some may even survive in harsh conditions.
