Answer:
In the gums
Explanation:
Lidocaine is a compound which can be used as a local anaesthetic. This anaesthesia works by blocking the voltage-gated channels which allows the influx of the sodium ions. As the sodium ions do not enter therefore an action potential is not generated in the axons as a result of which no pain is felt in the area.
In the given since the lidocaine is used by the dentist therefore the dentist in order to treat some dental problem must inject the lidocaine in the gums where the sensory receptors of the teeth are present.
Thus, in the gums is the correct answer.
True
Archaea thrive in many different extremes: heat, cold, acid, base, salinity, pressure, and radiation. These different environmental conditions over time have allowed Archaea to evolve with their extreme environments so that they are adapted to them and, in fact, have a hard time acclimating to less extreme conditions.
For the answer to the question above, I believe the answer is the<span> phylogenetic species concept</span>.
The key to the phylogenetic species concept is that species must be "diagnosable." In other words, members of the species should share a combination of characteristics that other species don't have. To look for some unique features that define a phylogenetic species, systematic comparisons must be done by paleontologists with other related fossils or living species
