Substances that are naturally produced by certain microorganisms that can either inhibit or destroy other microorganisms are called:
a)semisynthetic drugs
b) narrow-spectrum drugs
c) antibiotics
d) synthetic drugs
Regarding the cultivation of animal cells in vitro, it is correct to state that: *(Only one statement is correct)
a) Transformed cells differ from normal and established cells in that they have the ability to proliferate indefinitely in culture b) Transformed cells derive from isolated and dissected tumors, constituting cell lines that have limited cultivation time
c) The genetic instability presented in normal cells makes them preferential models for the production of recombinant proteins
d) Cells cultured in adhesion must be periodically expanded, through the use of enzymes such as trypsin
e) The metabolism of carbon sources in the culture medium by animal cells generates products such as lactate, which positively influence their productivity
Usually, bacteria only make tryptophan when
tryptophan is absent or available in low
concentration. However, a particular bacterial
mutation makes tryptophan all the time
whether or not tryptophan is present. What

Patient A got better and was released from the hospital in two days, but it took a week for patient b to recover and be sent home. That’s interesting though dr toboggan. “Why did the drug work differently in the two patients? Remedesivir seemed to help one patient but not the other. Maybe the drug speeds up recovery but the patients had different levels of infection. Or, maybe remdesvir didn’t have any effect on recovery, and the patients were just at a different places in their infections by the Novel corona virus. To find which hypothesis was a better explanation her data, Dr To boggan applies a little deductive reading. “What if I set up a situation where I have two patients at the same point in their infection and I give one the drug and one not? If remedesivir speeds up recovery, then the one with the drug will recover faster.
