Last Universal Common Ancestor (LUCA) CORRECT ANSWER Was a microbe of unknown type that lived about 4 billion years ago; the origin of all organisms. What is 16s small unit rRNA used for? CORRECT ANSWER It's used to study construct phylogenetic trees of organisms because it's highly conserved and hasn't changed much over time.

IB Biology 1.2 Latest Update Already Passed Resolution Resolution is defined as the shortest distance between two points that can be distinquished Explain why electron microscopes have a better resolution than light microscopes because the wavelength of the electrons is thousands of times smaller than the wavelength of light. Ultrastructure all the structures of a biological specimen that are at least 0.1 nm in their smallest dimension Something that electron microscopes can se...
