Answer:
D
Explanation:
it would be d as when organisms or plants die they would decay and the energy and nutrients and carbon would then be broken down and absorbed by the soil
The stomach normally secretes acid that is essential in the digestive process and this helps in the breaking down of food during digestion. Acidity is responsible for ulcer, dyspepsia, heartburn and the formulation of the ulcer. One way to experiment on how the acid is neutralized is by using vinegar and starch.

Answer:
C
Explanation:
The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.
A) The Dura mater
B) The arachnoid mater
C) The pia mater
The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.
The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.
The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.
