tresset_1 [31]

Answer:

The correct option is D. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.

Explanation:

Nitrogen is an active constituent of amino acids which make up proteins. Nitrogen is also an active constituent of the nitrogenous bases which make up an organism's DNA.

Phosphorus is actively present in the DNA but amino acids lack phosphorus.

Our body is actively made up of DNA and proteins. If the nitrogen was radioactively labelled, the experimental results would be wrong as proteins also have nitrogen in them.

rjkz [21]

Once the chyme begins to enter the duodenum, it must first be Neutralized before any of the enzymes in the pancreatic juices can be activated.

<u>Explanation:</u>

Chyme or chymus is the semi-liquid mass of halfway processed sustenance that is excreted by the stomach, through the pyloric valve, into the duodenum. Chyme results from the mechanical and compound breakdown of a bolus and comprise of incompletely processed sustenance, water, hydrochloric acid, and different stomach related catalysts.

Chyme gradually goes through the pyloric sphincter and into the duodenum, where the extraction of supplements starts. With a pH of roughly 2, chyme rising up out of the stomach is exceptionally acidic. The duodenum secretes a hormone, cholecystokinin (CCK), which makes the nerve bladder contract, discharging antacid bile into the duodenum.

The duodenum is a short segment of the small digestive tract situated between the stomach and the small digestive system. The duodenum additionally creates the hormone secretion to invigorate the pancreatic emission of a lot of sodium bicarbonate, which at that point raises pH of the chyme to 7 and this process is called as neutalization of chyme.
