<span>Carbon dioxide is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.</span>

Answer:
Amylase and protease enzymes act on daal eaten at lunch.
Explanation:
Daal is the Indian name of pulses. Pulses contains both protein and carbohydrates in large amount and our body cannot absorb these nutrients due to bigger size. For the absorption of these nutrients, they can be broken down into simpler substances with the help of enzymes. Amylase enzyme helps in the break down of carbohydrate while protease enzyme is responsible for the break down of protein.
