Biologists have long been aware that the defunct kingdom protista is paraphyletic. whichof these statements is both true and consistent with this conclusion? a) many species within this kingdom were once classified as monerans. b) animals, plants, and fungi arose from different protist ancestors. c) the eukaryotic condition has evolved only once among the protists, and alleukaryotes are descendants of that first eukaryotic cell. d) chloroplasts among various protists are similar to those found in prokaryotes. e) some protists, all animals, and all fungi share a protist common ancestor, but theseprotists, animals, and fungi are currently assigned to three different kingdoms.

The correct answer is option E

The kingdom Protista includes large diversity of organisms ranging from flagellated cells to macroscopic organisms. It is sometime referred as Protoctista instead of Protista. Some of the ancient Protista’s have characteristics of animal and plant kingdom. For example Lichen is not a protist but it includes the characteristics of both Protista and Fungi. Likewise organisms such as algae, bacteria, ciliates have the features of Protist as all these are Eukaryotic cells. Since the formation of kingdom Protista many animals have been included and excluded from the kingdom. Even today red and brown algae are considered as protist

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
