Which factor is least likely to affect the results and interpretation of a functional MRI?
fiasKO [112]

Answer:

None of the given options is correct. The correct solution is "Sprained ankle".

Explanation:

  • Brain activation is assessed by functional MRI via identifying causes an increase in blood flow. The assumption that brain blood flow and neural activity are linked is the basis of this methodology.
  • MRI allows excellent visualization of the structure of the ankle, allowing ligament defects and their related osteochondral including tendon disorders to be correctly identified. In patients with such an uncertain psychiatric history although with equivocal otherwise complicated psychiatric exams, MRI can be particularly useful for early diagnosis of syndesmotic lesions.  

All those other alternatives are not linked to a working MRI. Then the option above is appropriate.

Complete question:

Which correctly describes the set of clades that contain the arthropods, from largest to smallest?

  1. Archaea: Eukaryotes: Opisthokonts: Animals: Protostomes Ecdysozoa: Arthropods
  2. Eukaryotes: Opisthokonts: Nuclearia: Animals: Protostomes Ecdysozoa: Arthropods
  3. Eukaryotes: Opisthokonts: Animals: Deuterostomes Ecdysozoa: Arthropods
  4. Eukaryotes: Opisthokonts: Animals: Protostomes: Ecdysozoa: Arthropods

Answer:

4. Eukaryotes: Opisthokonts: Animals: Protostomes: Ecdysozoa: Arthropods

Explanation:

Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.  

  • The eukarya domain is composed of all the unicellular or pluricellular organisms that have eukaryotic cells that characterize by having a well-defined nucleus surrounded by a complex biological membrane. They also present organelles delimitated by membranes. These organisms reproduce asexually and sexually.  
  • Animalia Kingdom: Includes different phyla closely relates.
  • The embryonary development of bilateral coelom animals makes a place for the division of two groups: protostomes and deuterostomes. Among protostomes might be mentioned the flatworms, annelids, mollusks, and arthropods. Protostomes show spiral initial segmentation, and the mouth develops as a first opening near the blastopore.  
  • Ecdysozoan Superphylum: Their bodies are covered by a cuticle that provides protection. They have a complete digestive system. They might reproduce sexually and asexually.
  • Phylum Arthropoda: Invertebrates characterized for having an exoskeleton, a segmented body, and articulated appendixes. A very diverse group with many different characteristics.

List the advantages and disadvantages of the switch from persistent chlorinated hydrocarbon pesticides (such as ddt) to nonpersi
expeople1 [14]
Persistent chlorinated hydrocarbon pesticides persist in the environment and accumulate in the foods chain causing harmful effects on the environment including posing a threat to humans health in the long term. Nonpersistent organophosphate pesticides are more toxic than the former but degrade after a short life span. Therefore they cause immediate harm in case one is in contact with them.
The fact that they do not accumulate in the environment, they are more favourable than chlorinated hydrocarbon pesticides. Chlorinated hydrocarbon pesticides will affect several generations due to their accumulation in the environment. However they don't need to be re-applied hence are less expensive
