When thinking about human swimmers, which model of fluid drag most appropriate?
estimate the reynolds number for a human swimming in water. approximate the human as a sphere of radius 0.5m, swimming at a speed of about 11m/s. the density of water is approximately 1000kg/m³ and its viscosity is 0.001n/m².s.
a. re = 50,
b. re = 5 x 10⁵,
c. re = 2 x 10⁴,
d. re = 0.5,
e. re = 5 x 10⁵,

This did i unseated, sorry

Because its reliable.   there is no pollution  the chances of a radiation leak is low

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.
