The tentacle side branches are known as tentilla, which in the case of Euplokamis are held tightly in coils except during the act of prey capture. [12] Further, the widely spaced tentillia droplets allow for organisms to be classified to the genus level and are one of the only examples of striated muscle found in ctenophores. [13]
Leaves are 1–3 cm (0.39–1.18 in) in length, twice pinnately divided, usually segmented into 3 lobes and sometimes 4. Flowers are tubular, pink with a yellow tip, 1–1.7 cm (0.39–0.67 in) long, grouped into dangling clusters. Seeds are black and shiny, about 1 mm (0.039 in) wide, held tightly together in long thin cylindrical pods.
Freycinetia marginata is an evergreen root climber with a stem diameter of up to 3 cm (1.2 in), which is held tightly to its support substrate by numerous adventitious roots. [4] [5] The leaves have fine longitudinal veins and are green with a purplish hue. They are long and strap like, measuring up to 150 cm (59 in) long by 8 cm (3.1 in) wide ...
In other words, the difference between "the whole chromosome is a centrome" and "the chromosome has no centrome" is hazy and usage varies. Beyond "polycentricity" being used more about defects, there is no clear preference in other topics such as evolutionary origin or kinetochore distribution and detailed structure (e.g. as seen in tagging or ...
Static sumps may also be connected underwater to active stream passage. When short in length, a sump may be called a duck. Suspension trauma. Main article: Suspension trauma. Also known as harness hang syndrome (HHS), or orthostatic intolerance, is an effect which occurs when the human body is held upright without any movement for a period of time.
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
Porcelain crabs resemble true crabs, but are more closely related to squat lobsters and hermit crabs. [1]Carcinisation (American English: carcinization) is a form of convergent evolution in which non-crab crustaceans evolve a crab-like body plan.
It blooms in late summer or early fall, with 0.5 in (13 mm) flowers that are violet-blue at the edge and fading to white at the center. Many short and slender spikes with verticils of tightly held flowers give the plant its specific epithet polystachia. The leaves are yellow-green, 1 in (2.5 cm) long and wide, and grow in small clusters. [4]
