Explanation:
Pure substances contain only one element or compound.
Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.
The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.

Answer: c. Increased lactate production
Explanation:
The shock causes the deprivation of oxygen, this leads to anaerobic respiration in cells. In anaerobic respiration lactic acid production increases. The lactate get dissociated into lactic acid and hydrogen ions this makes the pH of blood more acidic. The acidic blood ruptures the blood vessels. This anaerobic process leads to the cell death. If enough number of cells die, the organs fails and death may occur.
