Explanation:
You can do two controls:
1) Check if the cells are viable by plating the transformed E.coli on LB medium with no antibiotics. If the cells are alive, a lawn will be seen, as there is no selection pressure. If the cells are dead, no colonies will be seen.
2) Check if the cells are competent by transforming them with a control plasmid. This is another plasmid, either commercial or already used in the lab, that contains the gene for resistance to kanamycin, and is known to work. If this positive control is used to transform the cells and still no growth is seen in the LB plates, then the E.coli are probably not competent.
XD I know this is weird for a guy to be answering this but I'm in wellness class so. the placenta is a flattened circular organ in the uterus of pregnant eutherian mammals, nourishing and maintaining the fetus through the umbilical cord. <span>The </span>placenta<span> is also an organ that develops in a female humans uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The </span>placenta<span> attaches to the wall of your uterus, and your baby's umbilical cord arises from it. The baby will come out malnourished or small or some kind of undergone experience and will die soon.</span>
