and 4 seconds?
a coat
.
O The object has decreasing acceleration and
increasing velocity.
O The object has positive acceleration and eventually
stops.
O The object has decreasing acceleration and
decreasing velocity,
O The object has negative acceleration and eventually
stops.

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

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.
