Answer:

Before accepting brain imaging studies, the inquiries that I would pose before believing these discoveries to be legitimate are:  

Did the investigation show up in a peer-reviewed journal?  

peer-reviewed implies presenting the exploration papers to different specialists for an alternate and free audit before accepting it. It is perhaps the most ideal way of finding out the reality of the study and how right the outcomes are. It is in every case great to go for the subsequent feeling.

One shows signs of improvement result when the investigation of populace is as homogenous as conceivable in light of the fact that it permits the specialists to reduce or diminish the quantity of contrasts that may influence the examination or result.

Gram-positive bacteria are bacteria that have thick cell walls which yield positive results in the Gram staining test. Lipoteichoic acid is a major component of the cell wall of gram-positive bacteria.

  • All bacteria indicated in the question can be classified by the Gram staining test:
  1. Actinomycetes are Gram-positive bacteria
  2. The genus <em>Arthrobacter </em>includes Gram-positive bacteria
  3. <em>Escherichia coli </em>(<em>E. coli</em>) is a Gram-negative bacterium
  4. <em>Staphylococcus spp.</em> are Gram-positive bacteria
  5. <em>Bacillus spp</em> are Gram-positive bacteria
  6. <em>Mycobacterium spp.</em> are Gram-positive bacteria

  • Prokaryotes can be divided into two domains: Bacteria and Archaea.

  • Gram staining is a method used to classify bacteria, but this method IS NOT USED to stain Archaea.

  • In consequence, I would not use the Gram test to stain Archaebacteria because Archaebacteria aren't bacteria (Option A is correct).

  • Archaebacteria belong to the Archaea domain.

nikitadnepr [17]
<h3>Your answer is D.</h3>

The insects are the same species.

<h3>Explanation:</h3>

A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.
