Answer:
C. because the common goal of basic science is to understand how things work, whether it is a cell, an organism, or a entire ecosystem.
Answer:
Every organism possesses in its ribosome a protein that is similar to rpl4. This protein has an amino acid sequence that is similar to the sequence of E. coli’s rpl4.
Explanation:
Phylogenetic tree is a diagram which represents the similarities between different organisms and shows their evolutionary histories.
The presence of a similar genetic sequence or amino acid sequence shows that the gene is common in all those organisms. This means that all organisms had a common ancestor through which the gene or amino acid was transferred. The genetic r amino acid sequence remained common in all the different organisms.
