Evolutionary tradeoffs can be present in a form called life history tradeoffs, which can be defined as the decrease in fitness (essentially, lifetime reproductive success) caused by one life history trait as a result of the increase in fitness caused by a different life history trait. [5]
The largest and most-known species, the so-called "giant amoeba" (Chaos carolinensis), can reach lengths up to 5 mm, although most specimens fall between 1 and 3 mm. [3] [4] [5] Members of this genus closely resemble those of the genus Amoeba and share the same general morphology, producing numerous cylindrical pseudopods , each of which is ...
Xenophyophorea / ˌ z ɛ n ə ˌ f aɪ ə ˈ f oʊ r iː ə / is a clade of foraminiferans.Xenophyophores are multinucleate unicellular organisms found on the ocean floor throughout the world's oceans, at depths of 500 to 10,600 metres (1,600 to 34,800 ft).
The single-celled giant amoeba has up to 1000 nuclei and reaches lengths of 5 mm. Gromia sphaerica is a large spherical testate amoeba which makes mud trails. Its diameter is up to 3.8 cm. [ 116 ]
This social cycle results in a differentiation between cells: ~20% are sacrificed to form a structural stalk, [10] some transform into sentinel cells with immune like and detoxifying functions, [4] and the rest of the aggregated amoeba form a ball of spores located in protective fruiting body. [8]
An amoeba of the genus Mayorella (Amoebozoa, Discosea). Amoebozoa is a large and diverse group, but certain features are common to many of its members. The amoebozoan cell is typically divided into a granular central mass, called endoplasm, and a clear outer layer, called ectoplasm.
The club’s net spend on player transfers hit a record £1.19 billion ($1.52 billion) between 2014 and 2023, according to the CIES Football Observatory—quadruple that of successful rivals ...
Amoeba proteus is a large species of amoeba closely related to another genus of giant amoebae, Chaos. As such, the species is sometimes given the alternative scientific name Chaos diffluens. [1] [2] Amoeba proteus in locomotion. This protozoan uses extensions called pseudopodia to move and to eat smaller unicellular organisms.
