21. The smaller organelle is the ribosome.
Answer: The correct answer is- to see what new traits might appear next.
As per the information in the question, pigeon breeder selects the offspring of pigeons with spotted bodies.
Spotted body is a trait that would be depicted by two different alleles ( such as one for black and other for white color).
As both the alleles for the color are represented in the pigeon offspring, therefore, it is a case of co-dominance ( let us take its genotype as Bb, where 'B' is allele for black and 'b' for white color).
When pigeons with spotted bodies are cross bred, they can produce pigeon with spotted and non spotted ( such as black 'BB', white 'bb', or spotted 'Bb' ) body depending upon the allele that is passed to the offspring.
Thus, pigeon breeder selects the spotted bodies pigeons and then breed those offspring to see what new traits might appear next.
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.
