Explanation:
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.

To make two daughter cells, the contents of the nucleus and the cytoplasm must be divided. The mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell, and then the cell is divided into two new identical daughter cells. The first portion of the mitotic phase, mitosis, is composed of five stages, which accomplish nuclear division. The second portion of the mitotic phase, called cytokinesis, is the physical separation of the cytoplasmic components into two daughter cells.
