Answer:
Archaebacteria
Explanation:
Carl Woese categorised the bacteria into two domains called the Archaebacteria and the Eubacteria.
The Archaebacteria is the group of bacteria which can survive in the extreme condition as they posses the characteristics of both the prokaryotes and some eukaryotes. The bacteria are known as the extremophiles.
In the given question, the bacteria which lives in the gut of the human uses methane gas and thus are known as the methanobacteria. These bacteria are considered the archaebacteria as they methane for survival.
Thus, Archaebacteria is correct.
Answer:
In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.
Explanation:
Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.
-
Na⁺ is a predominantly extracellular cation.
- K⁺ has a high intracellular concentration.
This distribution occurs when the membrane potential is at rest, with a negative intracellular value.
Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.
While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.
