Secretin increases the flow of bicarbonate ions from the pancreas into the small intestine to neutralize stomach acid.
Gastric acid regulation, pancreatic bicarbonate modulation, and osmoregulation are the three primary roles of secretin. Pancreatic fluid stimulation and bicarbonate secretion are two of secretin's main physiological effects.
Peptide hormones released by endocrine cells in the digestive system include secretin and CCK. While CCK enhances the synthesis and secretion of bile juice and pancreatic enzymes, Secretin stimulates the release of water and bicarbonate ions from the pancreas.
A pancreatic fluid that is high in bicarbonate is secreted when secretin is present. By interacting with pancreatic ductal cells, secretin enters the bloodstream or intestinal lumen and increases the production of bicarbonate, which lowers the pH of the gastric chyme as it enters the small intestine.

Answer:
Scientists found additional similarities between the frog genes and human genes. For instance, genes in frogs have very similar neighboring genes as humans about 90 percent of the time. In other words, the frog genome contains the same sort of “gene neighborhoods” as the human genome.

Answer:
Option a. met3, Met3p, MET3 is correct answer
"An investigator is studying mutants in methionine synthesis. The _met3_ mutants are unable to ATP sulfurylase, also known as _Met3p_. This protein is the product of the _MET3_gene. "
Explanation:
MET3 encodes ATP sulfurylase, which is a catalyst of first step of the sulfur assimilation pathway. This pathway results in the formation of hydrogen sulfide which is a precursor in the biosynthesis of cysteine, homocysteine, and methionine.

Answer:
The mass number is the sum of protons and neutrons. This means to find the number of neutrons you subtract the number of protons from the mass number. On the periodic table, the atomic number is the number of protons, and the atomic mass is the mass number.
Answer:

Phloem cells that surround sieve tube elements. The tough covering of the root tip that protects the meristem. The part of the plant structure containing apical meristem tissue that can produce new stems and leaves. The central region of a root that includes the vascular tissue -- xylem and phloem.
