Stalactite.
<u>Stalactite:</u>
- Often, stalagmites develop up from the cave floor, whereas stalagmites typically grow down from the cave roof.
- It's simple to distinguish between the two since stalagmites have a "G" for ground and stalactites have a "T" for top.
- Typically made of calcium carbonate, stalagmites can also be made of lava, mud, peat, pitch, sand, sinter, and amber.
- A single drop of water rich in minerals is the origin of all limestone stalactites.
- The smallest ring of calcite is left behind by the falling water drop.
- Another calcite ring is left behind with each new drop of water that develops and drops.

Answer:
Carbon is stored
Fossil fuel deposits and the Earth’s oceans are two places in which <u>carbon</u> is stored
Explanation:
This is because the organisms that lived millions of years ago in the sea died off and their remains were compressed at the bottom of the ocean from carbon, thus creating the fossil fuels that we have today. This process took thousands of years.
Answer:
The Ames test, named for its designer, Bruce Ames, is a technique to test synthetic compounds for their disease causing properties. Three analyzer strains are utilized for this reason - Escherichia coli , Salmonella typhimurium strain An and strain B. E. coli distinguishes base pair substitution change though Salmonella typhimurium strain B identifies frameshift transformation and strain A recognizes base pair substitution change. Acridine orange intercalates itself between adjoining bases and contorts DNA helix, subsequently causes additions and erasures during replication process. Along these lines it is utilized to decide frameshift change and this is the reason it seems mutagenic in Salmonella strain B yet not strain A. Sodium nitrite deaminates cytosine to deliver uracil and uracil thus matches with adenine shaping a CG to TA progress. Along these lines it is utilized to decide base pair substitution and that is the reason it seems mutagenic in Salmonella strain A yet not recolor B.
