The Theraphosinae are a large subfamily of Mygalomorphae spiders in the family Theraphosidae found primarily in the Neotropical realm. Genera
The plant body is a gametophyte.It consists of the main axis (differentiated into nodes and internodes), dimorphic branches (long branch of unlimited growth and short branches of limited growth), rhizoids (multicellular with oblique septa) and stipulodes (needle-shaped structures at the base of secondary laterals).
A further control on the morphology and characteristics of a deposit is the water to magma ratio. It is considered that the products of phreatomagmatic eruptions are fine grained and poorly sorted where the magma/water ratio is high, but when there is a lower magma/water ratio the deposits may be coarser and better sorted.

Magma consists of liquid rock that usually contains suspended solid crystals. [14] As magma approaches the surface and the overburden pressure drops, dissolved gases bubble out of the liquid, so that magma near the surface consists of materials in solid, liquid, and gas phases.
Thylakoid mambranes in cyanobacteria have a variety of different spatial distributions which are characteristic of different species, and these distributions have in the past been used to infer taxonomic relationships between species, but DNA evidence suggests that the type of spatial distribution does not reliably reflect taxonomic ...
This magma may be derived from partial melts of pre-existing rocks in either a planet's mantle or crust. Typically, the melting of rocks is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. [10]: 591–599 Igneous rocks are divided into two main categories:
The Zygnematophyceae, formerly known as the Conjugatophyceae, generally possess two fairly elaborate chloroplasts in each cell, rather than many discoid ones. They reproduce asexually by the development of a septum between the two cell-halves or semi-cells (in unicellular forms, each daughter-cell develops the other semi-cell afresh) and sexually by conjugation, or the fusion of the entire ...
The functions and organizations of the zooids in colonies widely vary among the different species; however, the majority of colonies are bilaterally arranged with dorsal and ventral sides to the stem. [7] The stem is the vertical branch in the center of the colony to which the zooids attach. [7] Zooids typically have special functions, and thus ...
