The electronics aboard a certain sailboat consume 50 w when operated from a 12.6-v source. if a certain fully charged deep-cycle lead acid storage battery is rated for 12.6 v and 100 ampere hours, for how many hours can the electronics be operated from the battery without recharging?

Ithink they do have the same properties just in less quantities i think

Then the answer would be d then

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.
