C. Agar provides a solid surface for bacterial growth.

Agar is a substance obtained from red algae which when added to a culture media, provides a solid surface for the growth of bacteria. When the agar is not added then the culture media remains as the broth and when the agar is added then the broth gets solidified.

Agar is added 1.5-2% in the broth to get solidified. The growth of the bacteria depends on the amount of agar added. Agar is used for the growth of bacteria because it has gel like properties which holds the nutrients evenly and the bacteria can use it accordingly.

At which type of tectonic plate boundary is a volcano least likely to occur?
Arlecino [84]

Answer:

Hotspot

Explanation:

Volcanoes can form in three different places: a convergent boundary, a divergent boundary, or a hot spot.

-At a convergent plate boundary, two plates collide and form a subduction zone. In the subduction zone, the denser, heavier plate goes below the more buoyant plate. The plate that goes under is subjected to immense heat and pressure and melts to form magma. This magma is less dense than the surrounding solid rock and rises to the surface through cracks in the plates to form a volcano.

- Volcanoes will form along divergent plate boundaries. A divergent boundary is when the plates move apart from each other. When the plates part, magma from under either plate rises and forms a volcano.

-A hotspot is the third place a volcano can form. This particular type is the least common. Hot spots are when thermal plumes from deep in the Earth rises. This heat, combined with the lower pressure at the bottom of the lithosphere, causes magma to form. The magma, as we discussed, is less dense than the surrounding solid crust and rises to the surface through cracks and channels and then erupts at the surface to form a volcano.
