To draw: The phylogenetic tree consisting of the several types of the protists, plants, algae, and the
Concept introduction: The phylogenetic tree alignment of the supergroup species of the protists, plants, and the algae consists of the placement of the species in the various groups. The branches represent the starting of the trees, roots, and the phylogenetic diversity and the distance of each species present in the group.
The broad spectrum of the antibiotic drugs is used for combating and controlling the infection caused by the growth and infection of various pathogenic strains of fungi, plants, prokaryotic bacteria, and small microbes. The ribosomal RNA sequence analysis of the genome is analyzed based on the homology and the similarity in the sequences present in the genome.
Given data: The given data include the names of the various protists in groups like the Excavata, SAR, Archaeplastida, Unikonta, amoebozoans, animals, choanoflagellates, fungi, and Nucleariida species.
