Answer:
The correct option is B
Explanation:
The <u>biomolecule used in comparing lizards A and B is the mitochondrial DNA while that used to compare the same lizard B to another lizard C is the ribosomal RNA (rRNA)</u>. <u>They should have compared the same biomolecules throughout</u> by extracting the mitochondrial DNA of the three lizards and then proceed to sequence the whole genome of the lizards. After which they can now do a Global alignment (comparison) of the three sequences together. This procedure would have given them a more accurate information on there identity and similarity.
Simple version:
6 levels of environmental organization
individual
population
community
ecosystem
biome
biosphere
complicated version:
Exploring levels of biological organization
Biosphere
Ecosystem
community
population
organism
organs
tissues
cell
organelles
molecules
They work together to benefit the entire organism, so that would be B
