Question 21 (1 point) Regarding olfaction, which of the following statements is FALSE?
Blows to the head can tear the olfactory nerve and cause anosmia.
There are roughly five million nerve fibers embedded in the lining of the upper
nasal passages.
Five people out of 100 experience some degree of anosmia.
The theory of smell that holds that odors are related to the shapes of chemical
molecules is known as the opponent-process odor theory.

show the wavelengths of a wave. show the crests of a wave.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
