<span>If Noam chooses a filter, it might be more effective than a screen. After using it for a while, though, he will have to replace it, which could be expensive. A screen might be less effective, but it can be cleaned instead of replaced.</span>
Answer:
Transcription, mRNA (processing, transport, localization and stability), translation.
Explanation:
- Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
- mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
- In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

Answer:
The correct answer is - it is essential to produce red blood cell and development of the spinal cord and brain.
Explanation:
Folic acid is natural form of vitamin B9 which is essential for producing red blood cells therefore the level of this vitamin should be in proper amount as in fetuses it is crucial for the various organs to develop,
The neural tube, spinal cord, and brain growth requires appropriate amount of folic acid in pregnant women. Low level of this vitamin can leads to the risk of various disease in baby
Thus, the correct answer is -it is it is essential to produce red blood cell and development of the spinal cord and brain.
