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.

Protists are eukaryotic organisms that cannot be classified as a plant, animal or fungus. They are mostly unicellular, but others like algae are multicellular. Protists have mitochondria responsible for respiration to produce energy to be used by cells. Additionally, they can be parasites and mostly prefer aquatic or moist environments. They may be classified as animal-like protists (heterotrophs and have ability to move), Plant-like (autotrophs that photosynthesize) and fungi-like (heterotrophs with cells that have cell wall and reproduce by spore forming). Protists reproduce by asexual means (e.g. budding) or sexually. Therefore, in this case we may conclude that they are all parasites and reproduce sexually or asexually.

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.

The relationship between fat content and calories in food selections is that caloric content increases as fat content increases,regardless of the protein source. Tom select that food for the proper nutrition.Even though eggs are a critical wellspring of cholesterol, Tom should consider a few information on the off chance that he chooses to purchase eggs,because eggs are good source of protein. for example, the Calories of one egg which is 80, complete fat 5 grams, soaked fat 1.5 grams, trans fat 0 grams, cholesterol 200 milligrams, and protein 7 grams.Salmon foods has the lowest unsaturated fat content per serving
