• A dog runs 33 m to the east in 9.0 s, then turns and runs 13 m to the west in 4.3 s. Assume movement to the east corresponds to positive displacement.
What is the average velocity of the dog?
What is the dog's average speed?

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.

It would be c hope this out
