Answer: Unicellular and microscopic features set the protista apart from the rest of the kingdom.
Explanation:
Protista are eukaryotic organisms that are neither plants, animals or fungi. They do not have a natural group with whom they share common ancestor. They have a unique features that set them apart from the rest of the kingdom which are unicellular and microscopic. Examples are amoeba, blue green algae, diatoms, green algae, ciliates and many more.
The best way is to compare the DNA of the two species. The more nitrogenous bases and amino acids two species have in common, the more closely related they are.
D cause it matches and I makes sense
Explain how amino acid sequence data can help scientists infer patterns of evolutionary relationships between species. ... A gene's DNA sequence determines the order of amino acids that make up a protein, so changes in the DNA sequence often result in changes in the amino acid sequence as well.
