Over time they build up forming the structure.

随着时间的推移，它们逐渐形成结构。

Bacteria and archaea mingle with other microbes like algae, fungi, and protozoa, forming dense, organized structures that grow on almost any surface.

水澡，真菌，原生动物等微生物，与细菌、古生菌混合，形成紧密、有序的能在几乎所有表面上生长的结构。

When water freezes, this bonding occurs on repeat, ultimately forming a hexagonal structure due to the angle between hydrogens and oxygen within each molecule.

当水结冰，这样的键合不断重复，由每个水分子内氢原子和氧原子的角度驱使最终形成一个六边形结构。
