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.

In salt water fish, chloride cells in the gills: a. actively transport Cl- from the plasma to the ECF. b. actively transport Cl-
lord [1]

Answer:

b. actively transport Cl- from the ECF to the external environment.

Explanation:

Chloride cells are cells that are found in the gills of teleost fishes which pump large amount of sodium and chloride ions out from the extracellular fluid (ECF) into the sea or environment against a concentration gradient in marine fish.

The opposite of this process occurs in freshwater fishes where the gills of freshwater teleost fish, cause an influx of sodium and chloride ions into the fish from the environment, also against a concentration gradient.

Mechanism of action

Salt water teleost fishes take in large amounts of seawater to decrease osmotic dehydration. The excess of ions derived from seawater is thrown out of the teleost fishes through the chloride cells. These cells employs active transport on the basolateral (internal) surface to diffuse in chloride, which then is pumped out of the apical (external) surface, straight into the surrounding environment. Such mitochondria-rich cells are located in the region of the gill lamellae and filaments of teleost fish.

What are hydrogen bonds caused by?
Musya8 [376]

Answer:

Hydrogen bonding is caused by the tendency of some atoms in molecules to attract electrons more than their accompanying atom. This gives the molecule a permanent dipole moment – it makes it polar – so it acts like a magnet and attracts the opposite end of other polar molecules.
