Answer:
lots of carbon dioxide and cold temperatures
Explanation:
<em>Calcium carbonate has low solubility at room temperature and the solubility increases as the temperature decreases. The solubility of calcium carbonate also increases in water with high level of carbon dioxide due to the formation of more soluble bicarbonate. </em>
<em>
</em>
<em>This is why carbon dioxide rich rainwater is able to erode limestone rocks, leading to the formation of caves, stalactites and other structures in the long run as a result of reversal of the process.</em>

As for function DNA is basically a string of genes and RNA is what converts the information in the DNA into proteins. DNA is the control molecule of the cell and sits in the nucleus. It is made of two strands, connected by hydrogen bonds. Each strand is made of nucleotides.
<span>Not all plants use the C4 or CAM
pathways to avoid photorespiration because they require a lot of extra energy
to perform their function. In photosynthesis, minimizing water loss is essential;
C4 plants relocate the carbon dioxide to lessen photorespiration while CAM
plants indicates when to extract carbon dioxide. Their function is also related
to plants survival where C4 plants is usually a summer plant while CAM plants
is suited to thrive in desserts. Therefore, only plants that need special
requirement to survival use these pathways.</span>
