<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 correct answer is letter A. The statement above is true that when animals eat the same type of food they are categorized in the same niche. Niches are ecological communities or ecosystems where specific organisms thrive and fit. Their evolutionary processes are also a result of these different niches found within the environment.
Answer:
They are similar in that both involve the growth of new organisms in an environment. However they differ in that primary succession occurs in a place where no life had been before, while secondary succession occurs in place where life had been before, but was destroyed.
Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after fire, harvesting, logging, or abandonment of land or the renewal after a disease outbreak.

Answer:
The reason hydrogen bonding occurs is because the electron is not shared evenly between a hydrogen atom and a negatively charged atom.
Explanation:
Hydrogen in a bond still only has one electron, while it takes two electrons for a stable electron pair. Any compound with polar covalent bonds has the potential to form hydrogen bonds.
