Which of these is the longest-lasting sink for carbon dioxide? a. plant tissues and cellulose (the "woody" parts of plants) b. the atmosphere c. air bubbles within glacial ice d. limestones?

The answer is: d. limestones

Explanation:

Carbon that is naturally deposited in a certain deposit in the form of solid carbonate. This is a process characterized by the fact that it occurs slowly and is the main responsible for the accumulation of the so-called limestone. Silicates react with carbonic acid in groundwater, it reacts and dissolves calcium, magnesium, and other alkalis. When an organism dies, its remains are deposited as sediment, thus transforming into limestone.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.
