<h2>Carbapenems</h2>
Explanation:
Carbapenems are bactericidal beta-lactam antibiotics that bind to penicillin-binding proteins (PBPs)
By binding and inactivating these proteins, carbapenems inhibit the synthesis of the bacterial cell wall, which leads to cell death
Each carbapenem has its own affinity to specific sub-types of PBPs whereas some bacteria demonstrate intrinsic resistance to the carbapenems
Generally, carbapenems work against various Gram-positive bacteria where they exhibit low minimum inhibitory concentrations on organisms like methicillin-susceptible S. aureus and S. pneumoniae
Carbapenems also have good activity against most Gram-negative bacteria, including Enterobacter, E. coli
The answer is C. Genetic drift is the change of an allelic frequency due to random sampling in a population. When the brown and black bottles are preyed upon compared to the green bettles, their numbers in a population decrease. Therefore the next generations/offsprings of bettles population is more likely to be of green beetles since they will be more in the parent population. The allelic frequency of the allele for green bettles becomes higher than that of brown and black beetles. Eventually, after generations, the black and brown beetles may be eliminated from the population
