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.
It takes place in the stroma
Answer:
In order to be useful in treating human infections, antibiotics must selectively target bacteria for eradication and not the cells of its human host. Indeed, modern antibiotics act either on processes that are unique to bacteria--such as the synthesis of cell walls or folic acid--or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or DNA replication. Following are some examples.
Most bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan, itself made up of amino sugars and short peptides. Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us.
hope this helps :) can i get brainliest?
Explanation:
This because ice is less dense than water of particular temperature range. Water reaches its maximum density at 4 degrees. Ice is important especially for aquatic life in the polar regions. Polar bears give birth and hunt on sea ice and they need it to travel from one region to another. The ice edge in coastal areas is an important feeding ground for the walrus that uses the ice as diving platforms to feed on clams on the sea floor. Ice algae grow at the porous bottom of sea ice and form the base of the unique marine food web connected to sea ice
