Answer:
Bacterial cell wall is made of peptidoglycan. A drug which inhibits NAG and NAM linking, inhibits cell wall formation which will lead to death of the bacteria. It will be more effective on gram positive bacteria since the peptidoglycan layer is very thick and there is no outer protection.
In gram negative bacteria the drug needs to cross the outer membrane first to access the cell wall which is not easy. Outer membrane can also evolve its properties to resist the antibiotic like altering its permeability or rendering useless the porins used by drug for transport. <em>Bordetella pertussis </em>is a gram negative bacteria hence is usually resistant to drugs like penicillin which target cell wall synthesis. Hence, the drug would not cause mortality in <em>Bordetella pertussis.</em>
The appearance of MPF activity in the absence of protein synthesis suggests that an inactive precursor of MPF is being activated. In principle, activation could involve one of several kinds of post-translational modifications such as protease cleavage or changes in protein phosphorylation. From class you know that MPF is held in an inactive state by phosphorylation of an inhibitory site of Cdk. MPF is activated when that inhibitory phosphate is removed by the protein phosphatase, Cdc25.
I'm pretty sure the answer is B. Invest in alternative energy sources that do not burn fossil fuels. The reason I would pick B is because in Antarctica the ice is melting more and more over time because, cars and factors etc are burning fuels which result in more damage to the ozone layer.
Answer:
I am not 100% sure but my best guess would be the object is moving backwards/falling.
Explanation:
The graph shows the position of the object going from almost 9.0 to below zero. There are many situations that could fit this. Such as, something going above and below sea level. OR something moving in front and behind a certain point. My best guess would be moving backward towards an object OR falling from a certain point.
The answer to the above question is the Mendel's law of independent assortment. Mendel's law of independent assortment states that the alleles of two or more different genes get sorted independently into gametes of one another . That is the allele a gamete receives for one gene does not influence the allele received for another gene.
