Answer:
Pancreatic juice, NaHCO₃.
Explanation:
The buffers are the chemical solution which neutralizes the acidic effect and the human body also produces the biological buffers which help maintain the pH.
The pancreatic juice secreted by the pancreas gets drained into the duodenum of the small intestine and neutralizes the effect of the acidic content in the stomach bolus. The pancreatic juice contains the sodium bicarbonate which neutralises the effect of the HCl.
Thus, Pancreatic juice, NaHCO₃ is the correct answer.
I don't understand, what is the question you're supposed to answer?
Answer: They contain DNA and RNA, they can exhibit a wide range of lifestyles, and they are essential to almost every ecosystem.
Explanation:
1) occluding junctions
2) anchoring junctions
3) communicating junctions
Occluding junctions do not totally seal the space between cells and the resulting permeability varies greatly. I would say anchoring junctions are most likely with one of the other 2 junctions being least permeable.
