Answer:
Enzymes are proteins that catalyse (speed up) vital chemical reactions inside the body. Enzymes will only function properly under a small range of certain conditions, such as preferred pH and temperature. If any conditions are outside their specific range then the enzymes cannot function. This could cause the organism to die. Homeostasis relies on automatic control systems that include nervous responses (nervous system) or chemical responses (endocrine system). Receptors and effectors are also needed

Answer:
The results from this experiment conclude that all of the resulting bacteria contain the pUC18 plasmid without the human gene.
The method of genetic engineering might seem very easy but in actual it is a very difficult task and most of the time a person won;t get the expected results. The chances of a vector to actually take up a recombinant DNA are very less. Even after this, the chances of a recombinant plasmid to enter a bacterial cell by transformation are very few.
