Yes they should be viewed as nonliving. Because viroids are just like viruses without protein coats. They are similar to viruses excepte the protein coat. And prions are like malfunctioned proteins. They cause diseases too but they are non-living too. Because they too, don't have any metabolics reactions.

pshichka [43]

Answer:

The condition is called "Spinal Bifida", caused by lack of vitamin B12 which helps regenerate the active form of folate.

Explanation:

Because Lori is a vegan, her vitamin B12 intake which comes from animal products such as meat, is not enough. She has to take supplements to make up for the lack of it in her diet.

As stated in the question, this lack of vitamin B12 causes her child to have a defect in his spinal cord called Spinal Bifida that defines a spinal cord or spine that has not fully developed. The vitamin B12 is necessary for regenerating the active form of folate.

I hope this answer helps.

What are the primary mechanisms by which E. coli regulates the amount and activity of its heat-shock sigma H?
Ratling [72]

Answer:

Option b (proteolysis by chaperones) and Option e (translational control) would be the correct options.

Explanation:

  • In addition to transcriptional control as well as mRNA compliance, translational management systems seem to be the most deciding factors for finished protein expression.
  • Besides protein biosynthesis, a substantial majority of optional extra systems that determine the ribosome on the first day of transcription initiation, deformation, but mostly termination were mostly permitted.
  • Limited proteolysis usually happens during which extremely specialized proteases fundamentally modify proteins.

The other choices are given aren't linked to something like the scenario in question. So, the solution here is just the right one.
