If you are the head of production, there are several things that you most likely need to do in order to address this problem.
First of all, you are responsible for finding out what the source of the contamination was. This would mean investigating every part and component of the production line, including raw materials, equipment and employees. Once the source of the bacterial contamination is found, you are responsible for dealing with it appropriately.
If after getting the fermentor back on line you get a recurrence, you might be forced to close for a period of time while you examine the situation more closely. You might also benefit from getting rid of the source of bacterial contamination permanently.
Answer:
A) all living things are made of cells.
Explanation:
Cell theory is presented by Matthias Schleiden in 1839. Cell theory states that "all the living organisms are madeup of one or more cells". Cell contains nucleus in the center which controls all activities of the cell. The organelles which are present in the cell are mitochondria, lysosomes, ribosome, cytoplasm, endoplasmic reticulum, golgi bodies and vacuoles. Every organelle has its own function.
Answer:
A) One band of intermediate density and one band of heavy density.
Explanation:
According to semi conservative model of replication the two DNA strands separate during replication such that the new DNA molecule has one parental strand and one new strand. In this experiment, originally E.Coli cells were grown in 14N medium so all the DNA strands had 14N. When the medium was changed to 15N, only 15N would be available to the cells for replication.
After first round of replication all DNA molecules would be of intermediate density as one strand would be old 14N strand and another would be new 15N strand. After second round of replication 15N strand would be formed from both 14N strand and 15N strand. So, one band will be formed of intermediate density (14N-15N) and another would be of heavier density (15N-15N).
Answer:
A. Mid ocean ridge
Explanation:
A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
