friend tells you the following story. "My aunt just received a heart transplant. Her doctors warned us that her body might reject the tissue. I just can't understand how that could happen as human hearts are made of the same tissues, aren't they?" What could be your best possible response to this? Note: This is a multiple question, choose the correct answer below: "Yes, all human hearts are made of cardiac muscles. As far as the rejection issue, everyone has different MHC proteins on their tissues. Your aunt's immune system recognizes the ‘self' tissues but can cause tissue rejection because of the ‘nonself' tissue in her body having different MHC proteins." "Yes, all human hearts are made of cardiac muscles. As far as the rejection of tissues goes, your aunt might have different antibodies than did the donor, which could lead to a rejection." "Yes, all human hearts are made of cardiac muscles. However, your aunt might have been given some type of drug during the transplant operation that might cause tissue rejection. You can never be too careful in a hospital, you know." "Yes, all human hearts are made of cardiac muscles, except some humans have different tissues inside their hearts and this could lead to a tissue rejection by the recipient."
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.
