Answer: The hormones secretin and cholecystokinin act on the pancreas, stomach, and gallbladder.
Explanation:
The duodenum produces two more hormones. Cholecystokinin (CCK), similar to enterogastrone, is released when fat is present in the chyme. CCK promotes the contraction of the gallbladder, which releases bile into the duodenum to help emulsify and digest fat more effectively. The other hormone from the duodenum is secretin. In response to the acidic chyme entering the duodenum, secretin triggers the pancreas to release bicarbonate, thereby neutralizing some of the acid.
Option C is the right choice. Since the start of industrialization in the 1800s, the concentration of carbon dioxide in the atmosphere has risen <span>. This increase is attributed to emissions from industrial machinery and vehicles.

Population density = total number of individuals divided by land area
land area should be expressed in square kilometers
thus, 120 ha = 120 x 0.01 = 1.2 square kilometers since 1 ha = 0.01 square kilometers
total population= (80 x 1500)/100 = 1200
so, the population density is 1200/1.2 = 1000
