If a log rolled for 10 minutes and went 1 mile, what was the average speed of the log?

time(t)=10min 10×60 =600sec

distance(d)=1×1.609=1.609×1000 1609m

average speed =?

now,

average speed =total distance/total time taken

=1609m/600sec

=268.17m/sec

Explanation:

this is all

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
