Both "turn on" factors (hormonal, humoral, and neural stimuli) and "turn off" factors (feedback inhibition and others) may be modulated by the activity of the nervous system. t/f

True.

Explanation:

Nervous system is one of the most important systems of the body that regulate the control and coordination of the body. Nerve cells are the basic structural unit of the nervous system.

The turn on factors like hormonal, neural stimuli can be modulated by the activity of the nervous system. The turn off factors like feedback inhibition can be controlled or altered by the nervous system.

Thus, the answer is true.

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.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
