Answer:
It will enable gut enzymes to act on the bolus during digestion.
Explanation:
The acidic presence of HCl (hydrochloric acid) in the gastric juice serves as a stimulus for the intestinal wall to produce secretin.
This hormone will act on the pancreas by stimulating the production of pancreatic juice that will contain <u>enzymes</u> (trypsinogen, amylase, lipases) and <u>HCO3⁻</u> (bicarbonate) salts, which have base composition.
With this composition that will be sent to the duodenum, there will be neutralization of acidic solution coming from the stomach and pH leveling around 8.0 (slightly basic) which is great for the enzymes that work there.
Answer:
The correct answer is (b)-False
Explanation:
Bacteria do not undergo meiosis or mitosis to reproduce and increase its genetic recombination. To increase their genetic recombination bacteria take the help of horizontal gene transfer through which it gets the genetic material of another bacteria. This new gene helps bacteria to survive in the challenging environment.
Bacteria divide through binary fission in which one cell of bacteria divides into two equal daughter cell each having its genetic material because genetic material of parent cell segregate equally into both the cell.
Therefore bacteria do not undergo meiosis or mitosis.
