Magnetic field lines always forms closed loop in such a way that it originates from North pole and then terminates back into the South pole
Inside the magnet we will draw the field lines from south pole to north pole
So it is not possible that magnetic field lines originates from north pole and again terminates at the same pole
So this is
FALSE
Answer;
B. both a non-directional and directional hypothesis
Explanation;
A two-tailed test is the standard test of significance to determine if there is a relationship between variables in either direction. Two-tailed tests do this by dividing the .05 in two and putting half on each side of the bell curve.
A non-directional hypothesis is a type of alternative hypothesis used in statistical significance testing. In contrast, a directional alternative hypothesis specifies the direction of the tested relationship, stating that one variable is predicted to be larger or smaller than null value, but not both.

</span>The receptor senses environmental stimuli, sending the information to the integrating center.
