Under normal conditions, some interstitial fluids slowly escape through the epidermis via a process called ______ water loss.
katrin [286]

Under normal conditions, some interstitial fluids slowly escape through the epidermis via a process called epidermis/trans-epidermal water loss.

Interstitial fluids are the fluids filled between the spaces present around the cells. This fluid is present due to the leakage of substances from the blood capillaries. It also aids in transport of oxygen, nutrients and removal of waste product from the cell.

Epidermis/trans-epidermal water loss is the passive evaporation of water from the skin. This is the reason why skin sometimes may feel very dry after a person wakes up. This evaporation happens de to the presence of water vapor gradient across both sides of the skin.

All of the following techniques involve hybridization between single-stranded nucleic acid molecules except:
Savatey [412]

Answer:

RFLP analysis.

Explanation:

RFLP (Restriction fragment length polymorphism ) may be defined as a molecular technique used to determine the location of a particular gene in the DNA sequences. The individuals among the population can be easily identified by RFLP analysis.

The restriction enzyme is used for the digestion of DNA sample. The restriction fragments are then visualized by running the fragments on gel electrophoresis. The hybridization between single stranded nucleic acid is not involved in the RFLP.

Thus, the correct answer is option (1).

Glucose labeled with 14C in C-3 and C-4 is completely converted to acetyl-CoA via glycolysis and the pyruvate dehydrogenase comp
Morgarella [4.7K]

Answer:

The correct answer is option d.

Explanation:

The production of Acetyl-CoA takes place by the dissociation of both carbohydrates and lipids in the process of glycolysis and beta-oxidation. It then moves into the TCA cycle in the mitochondria and combines with oxaloacetate to give rise to citrate.  

In the given case, no labeling will be found in the acetyl-CoA. The labeled C3 and C4 carbon of glucose signify the carboxyl carbon of pyruvate. In the succeeding reactions of the transformation of pyruvate to acetyl-CoA, the carboxyl carbon gets lost in the form of carbon dioxide. Thus, acetyl-CoA does not comprise any labeled C3 and C4 of glucose.
