and hear The potential answers are positive Negative feedback in
a minute All right Well a fino typical variation simply
put refers to the variability and few types that exist
in a population It's Why a box or is much
larger than a chihuahua and the nose of a collie
is way way longer than that of a pug So
answer See is not what we're looking for A genetic
mutation is a permanent alteration in the dna sequence that
makes up by jean Bye Bonzo here has one blue
eye and one green eye When why the chinese crested
dog is hairless But genetic mutation is not the reason
why dogs pant when they're hot So the answer d
try Try again Now think of a feedback mechanism is
a siri's of checks and balances within an organism When
a dog's temperature rises its blood vessels dilate in the
sweat plans begin to secrete a fluid all is well
and good except for one tiny detail Because we mentioned
before dogs do not have sweat plans so this positive
feedback mechanism cannot kick in to cool down our canine
friends We need jake japan can't jake pants by panting
a dog will use the largest gay patch of its
mouth to eliminate internal heat and bring its body temperature
back down to normal The correct answer is b always
remember that a negative feedback mechanism works to maintain homo
stasis in an organism by monitoring and controlling physiological processes
Bottom line be grateful Humans have sweat otherwise that's not 00:01:38.048 --> [endTime] pretty
