Answer from: jake2920

Converging plates in subduction zones often become locked. Pressure builds in the rocks until they fracture. If the break is along hundreds of kilometers of fault line a megathrust earthquake occurs.The breaking rocks allow the overriding plate to slip over part of the subducting plate all along the fault line. The plate movement on the ocean floor can cause a tsunami. The 2004 Indian Ocean tsunami was triggered by a megathrust earthquake at a convergent boundary.

Introduction
Convergent boundaries form when two crustal plates are colliding. The plates form a subduction zone with one plate descending beneath the other plate. One of the converging plates must be an oceanic plate to form a subduction zone. When two continental plates collide mountain ranges like the Himalayas form.

Subduction zone
The subducting plate is being recycled as it begins to melt at about 100 kilometers. The water soaked oceanic plate forms molten rock that collects in magma chambers.

Buoyant molten rock
The molten rock is buoyant because it is hotter and less dense than the surrounding rocks. The rocks move up through the overlying rocks to erupt at volcanic vents forming an arc of volcanoes on the continental side of the subduction zone.

Causes a megathrust earthquake
Converging plates in subduction zones often become locked. Pressure builds in the rocks until they fracture. If the break is along hundreds of kilometers of fault line a megathrust earthquake occurs.

Causes of tsunami waves
The breaking rocks allow the overriding plate to slip over part of the subducting plate all along the fault line. The plate movement on the ocean floor can cause a tsunami. The 2004 Indian Ocean tsunami was triggered by a megathrust earthquake at a convergent boundary.

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
