Answer:
The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.
Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.

Answer:
1. Endocrine
2. Exocrine
Explanation:
The pancreas serves as both endocrine and exocrine gland.
The pancreas is an exocrine gland as the pancreatic acini produce digestive enzymes that are delivered to the small intestine through a network of ducts. The glands that release their secretions by ducts are called exocrine glands.
Islets of Langerhans scattered among pancreatic acini serve the endocrine part of the pancreas. The alpha cells of pancreatic islets secrete hormone glucagon while the beta cells of the islets secrete the hormone insulin directly in the bloodstream. Likewise, the delta cells of pancreatic islets secrete hormone somatostatin. The ductless glands that release their secretions directly into the bloodstream are known as endocrine glands.
Answer:
The correct answer is C. Frequency.
Explanation:
In statistics, frequency is called the period of time that elapses between a certain event developing and repeating itself again. That is, the frequency measures the duration of the process of repetition of a certain event.
Thus, for example, if an earthquake occurs exactly every 4 months in a certain place, this natural catastrophe occurs with a frequency of 4 months.
Therefore, if the limits of a certain type of aquafarming pest during the farming of catfish might not to recur more than once every 6 months, this expression refers to the frequency with which said event must (or in this case, not must) happen.
Answer:most protozoa (prevalently attached ciliates) can only graze on suspended bacteria and particles; in this way they have a significant effect on the effluent quality.
Explanation:Even though some protozoa (crawling ciliates and other forms) can eat flocculated bacteria, most protozoa (prevalently attached ciliates) can only graze on suspended bacteria and particles; in this way they have a significant effect on the effluent quality.
