Transgenic organisms are those that have had their genomes altered by external means. These organisms are found in applications of genetic engineering, but they are only useful if the inserted gene is expressed in the organism.
An example of a transgenic organism may be a rat with the gene for hemoglobin from a rabbit. This rat is only useful if it indeed does produce rabbit hemoglobin in its blood due to the inserted gene.
The type of muscle tissue that does not contain gap junction is SKELETAL MUSCLES.
Gap junction function by allowing the free diffusion of ions and small molecules between two cells. The number of gap junction between any two cells will vary and will depend on the type of cell they are.
Frozen pipes are likely to bust and cause a leakage
The only answer that is not an example of a cell specialization is :
<span>Bacteria cells are small in size in order to easily diffuse in and out of the cytoplasm.
All of the other examples, the muscle, nerve and the rod and cone cells have specific cell structures, shapes, and proteins that enable them to execute their specific roles in the organism. </span>
