Answer:
40km
Explanation:
Average speed can be computed with the equation:
So we know the average speed and one of the distances is already given and we need to know how much it traveled after that. The total time the car traveling is 2 hours. Let's plug that in our equation:
Now let's multiply both sides by 2 hours:
Cancel out the hours and multiply:
Subtract 100km from both sides of the equation:
The main signal in small intestine for pancreatic bicarbonate ion secretion is Secretin.
When food from the stomach with acidic medium enters duodenum(first part of small intestine) it stimulates the lining of duodenum cells to release the hormone secretin.
This hormone travels via bloodstream to pancreas and stimulate to it to release bicarbonate ions.Now these ions enter duodenum and neutralise the acidic medium.
This results in the optimum pH for the enzymatic action to take place thereby promoting final digestion of protein.
