The ________ is the decorated niche inside a mosque that indicates the direction of Mecca.
Aneli [31]

Answer:

The correct answer to the following question will be "Mihrab".

Explanation:

  • A semicircular niche throughout the wall of a mosque showing the qibla; that is, the direction of the Kaaba in Mecca, and hence the way that Muslims will face while they pray. Thus the wall into which a mihrab appears was the "qibla wall."
  • A chanter calling for people to pray. Fana is a religious figure; in fact, a few of Muhammad's hereditary predecessors, worshiped in Shiite Islam.
  • It is traditional, when entering a mosque, to remove somebody's shoes and put them on the entrance rack. This is accomplished out of respect and also to avoid soiling the interior floor of the prayer hall — prayer halls do not have chairs or benches, just row after row of carpets, aligned to face the holy sites of Mecca in Arabia.

denis-greek [22]

Answer:

The inhibitory transmitter activates ligand-gated potassium channels

Explanation:

When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm  to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.

However, with the addition of  inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium  gated channels, which  were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.
