This is a physics question, not biology, but...
f=1/T where f is frequency and T is the period.
f= 1/(1/3)=3
frequency =3 Hz
Answer:
Mobility.
Explanation:
Mobility is the term used for all types of movement such as walking , running, swimming and flying etc. Mobility refer to the movement, those organisms which has the ability to move from one place to another is known as mobile organisms e.g lion, birds, tiger and humans etc, while on the other hand those organisms that are unable to move from place to place is called immobile organisms.
D) creates a variety of intercellular enviroment
The best method for studying both the structure and the function of the brain would be the functional magnetic resonance imaging (fMRI).
This technique measures the blood flow to different brain regions in order to determine which areas are active in certain brain processes. An increase in the blood flow increases the amount the oxygen the area is receiving that is needed for the functioning of the nerve cells.
