Answer:

The correct answer is C. In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.

Explanation:

The plaque assay is an approach used for titering bacteriophage stocks or determining the quantity of infectious virus in a sample. Plaques are visualized if you spot the phage on a lawn of growing compatible bacteria. Each plaque indicates an initial infection with one phage followed by lysis of neighboring bacteria in the lawn. Only viruses that cause visible damage of cells can be assayed in this way. The plaque assay is used to determine viral titer as plaque-forming units per ml so that known amounts of virus can be used to infect cells during subsequent work.

In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.

Why do water molecules “stick together”?
fredd [130]

Answer:

Water is sticky and clumps together into drops because of its cohesive properties, but chemistry and electricity are involved at a more detailed level to make this possible. More precisely, the positive and negative charges of the hydrogen and oxygen atoms that make up water molecules makes them attracted to each other.

You have to find the acceleration first. so you would use the equation a=Vf-V0/t.
This would be 0-20/0.5 which equals to be a=-40. then you plug this in to the force equation wich is F=ma. F=55 x -40.  F= -2200

Hope this helps!

FrozenT [24]

Answer:

GLD-1 is a regulatory protein whose function is to regulate the expression of MES-3.

Explanation:

Since the MES-3 protein itself is not modified but only its quantity is, then it is likely that the GLD-1 protein is only inhibiting MES-3's expression; keeping it at a certain  level set by the organisms DNA.

The image below shows a convergent plate boundary.
JulsSmile [24]

Answer:

the answer is volcanoes

Explanation:

The oceanic crust collides with the continental crust to form a convergent boundary. At the convergent boundary, the denser oceanic crust sinks under the lighter continental crust. The rocks of the oceanic crust reach very high temperatures of about 12,000°C, which is enough to melt the rocks. These molten rocks travel upward through cracks and crevices in the continental crust. They then erupt on the surface as volcanoes. Therefore, the feature expected to form at point X as the result of converging plates would be volcanoes.
