Question

explain the process of digestion in human beings​

Answer 1

Explanation:

The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body. The digestive organs also move waste material out of the body. The enzymes in saliva help break down foods, and the lubrication function of saliva makes it easier for food to be swallowed.

Answer 2

Answer:

Perimeter of trapezium = 104 m

Length of Non-parallel sides = 18 m and 22 m

Altitude = 16m

Area of Trapezium = 0.5 * (sum of parallel sides)*altitude ------ (1)

Sum of parallel sides = Perimeter - (sum of non-parallel sides) = 104 m - (18+22)m = 104-40 m = 64 m

From (1), Area of Trapezium = 0.5*64*16 = 512 m^2

Ans: Area of trapezium = 512 m^2
