Answer:
Basically the translation of CK-B protein is inhibited in the U937D cells, despite the fact that the CK-B protein is bounded to the ribosomes. This is because(<u>mechanisms)</u> the translation is inhibited by the binding of translational repressors to the 3’UTR of the CK-B mRNA rather than the actual CK-B mRNA 3'UTR.
Furthermore, the soluble protein inhibitions is due to the reaction of the U937 cells to the short RNA sequences with the 3’UTR.
<u>The introduction of these sequences(shot segement of RNA) </u>into the U937D cells leads to CK-B synthesis. This makes 3’UTR sequences to bind to the translational repressor proteins, thus preventing them from binding to the CK-B mRNA

COMPLETED QUE.
A common feature of many eukaryotic mRNAS is the presence of a rather long 3' UTR, which often contains consensus sequences. Creatine kinase B (CK-B) is an enzyme important in cellular metabolism. Certain cells—termed U937D cells—have lots of CK-B mRNA, but no CK- B enzyme is present. In these cells the 5’ end of the CK-B mRNA is bound to ribosomes, the mRNA is apparently not translated. Something inhibits the translation of the CK-B mRNA in these cells. Researchers introduced numerous short segments of RNA containing only 3’UTR sequences into U937D cells. As result, the U937D cells began to synthesize the CK-B enzyme, but the total amount of CK-B mRNA did not increase. The introduction of short segments of other RNA sequences did not stimulate the synthesis of CK-B; only the 3’UTR sequences turned on the translation of the enzyme. Based on these results, <u>purpose a mechanism for how CK-B translation is inhibited in U937D cells. Explain how the introduction of short segments of RNA containing the 3'UTR sequences might remove the inhibition.</u>

Explanation:
Light energy in ATP has to be converted from light to chemical energy. So im not really sure. Wouldn't we be getting our energy primarily from other animals?
It is a basin
Explanation:
The Midwestern region is made up of sedimentary rocks because it is a basin. In a basin, sediments accumulates and they form sedimentary rocks there.
- Sedimentary rocks are rocks that are laid down in natural depression on the earth surface.
- These depressions serves as the collection point of sediments from different sources.
- When wind, water glaciers brings materials here, they settle and accumulate.
- Compaction, cementation and lithification of sediments occur here and sediments are transformed into sedimentary rocks.
Therefore, the Midwestern region must have been a basin for sedimentary rocks to have formed there.

Acute transfusion reactions usually have symptoms within 24 hours of having the blood transfusion. When there is a transfusion reaction, the transfusion should be stopped right away and a normal saline solution be given as an Intravenous fluid. Corticosteroid or Diphenhydramine medications may help taper the symptoms.
