Um drone fez três voos sucessivos, descritos pelos seguintes deslocamentos: 3,2 km a 45o ao sul do leste; 5,3 km a 26o ao norte do oeste; 2,6 km a 18o ao leste do sul. Determine o vetor deslocamento resultante.

Does this your question?

The purpose of a lab is to do your "expirements" the importance of the topic is so you can now what the story is about and the last one is because no one is me with my question ( what is 3 over 4 x - 9 = 27 maybe you can )

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.
