2. What procedure did you use to complete the lab? Outline the steps of the procedure in full sentences. Virtual Lab: Water Eros
Anettt [7]

The procedures that can be used to perform water erosion laboratory practicals are:

  • The use of detachment
  • Transportation
  • Deposition.

<h3>What is Water Erosion?</h3>

This refers to the biological process where rock particles are broken down into smaller particles and how they are removed by water.

Hence, we can see that in a laboratory experiment, one would need different apparatus such as:

  • Pitchers
  • Bottles
  • Soil
  • Water, etc.

This would be used to test the loss of water as it is put into the soil from the set of bottles to see how much the water is retained.

A farmer ,sangay , plants chilli in the first year .He than plants beans in the same field next year ..
Gnom [1K]

Answer/Explanation:

Chilli and Beans are two different groups of crops having different nutrient requirement for them to grow well.

Beans is a leguminous crop that can help fix nitrogen back to the soil after the soil nitrogen content has been depleted by crops that use up nitrogen in the soil.

So, one of the possible reasons why Sangay plants Chilli the first, and beans the next year could be to ensure optimal productivity, as beans would replenish the soil with nitrogen. Also, both crops have different nutrient requirement. Nutrient requirement for both crops vary.

In the plaque assay for bacteriophages, A. only temperate phages may be used. B. the plaque is an opaque area caused by a high c
arsen [322]

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.
