Which characteristics do all protista have in common? they are all autotrophic and mobile. they are all heterotrophic and produce spores. they are all parasites and reproduce sexually or asexually. they are all unicellular and lack cell specialization.

Unicellular and lack of cell specialization is a common feature of all the Protista.

Further Explanation:

Protists produce generally by the means of sexual reproduction. They undergo in meiosis that is a reductional division and produce haploid cell. Protists are deliberated as first eukaryotes to be recognized. They are unlike from prokaryotes as they have a distinct cytoskeleton. They also comprises of different organelles and nuclear covering. Protists have a diverse range of cell surfaces and can easily survive in any unfavorable environment because of the presence of outer cover. They have “Flagella” for the propulsion. They can be either autotroph or heterotrophs as they ingest food by pulling them in the “intra-cellular vesicles” denoted as phagosomes or vacuoles. They can yield by the means of sexual and asexual process. Protista produces through meiosis, which is a “reductional division” causing the materialization of haploid cells. The progeny produced by the merger of two haploid cells allows the formation of new allelic grouping by genetic recombination.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.
