This is the partial amino acid sequence for cytochrome-C, a protein that carries oxygen in the blood. Based on the amino acid sequence, which organism is LEAST like humans?

Which mantle is under the crust the upper mantle or the lower mantle i think it's upper let me know if i'm right

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.

Drag the tiles to the correct boxes to complete the pairs. match the nitrogenous base of dna with its complement.
