________ sweat glands are widely distributed across the body surface, ________ glands are located wherever hair follicles exist,
ss7ja [257]

Answer:

<h2>merocrine, sebaceous, and apocrine</h2>

Explanation:

Merocrine: merocrine sweat glands are widely distributed across the body surface,

Sebaceous glands are located where hair follicles have existed,

apocrine sweat glands are found only in a few areas like axilla. Apocrine -are restricted to specific areas like the axilla, nipple of the breast, pubic region and around the anus area etc.

Describe the responses of a plant cell in isotonic, hypertonic and hypotonic solutions.<br>​
aksik [14]

Explanation:

A plant cell will remain stable in an isotonic solution.

A plant cell will shrivel in a hypertonic solution (the water inside the cell will leave into the exterior of the cell).

A plant cell will expand in a hypotonic solution (the water outside of the cell will enter into the plant cell because there is a lower solute concentration outside of the cell).

U937D cells express high levels of creatine kinase (CK‑B) mRNA but do not translate the mRNA into protein. Ribosomes bind the 5'
RUDIKE [14]

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>
