The true statement among the statements given is " Inner and outer planet composition supports the nebular theory because heavier elements condense close to the Sun, and lighter <span>elements condense at cooler temperatures". This is why terrestrial planets like Earth, Mars, Venus, and Mercury are closest to the sun and are very dense.</span>
Graded potentials are delivered approximately with the aid of using outside stimuli (in sensory neurons) or with the aid of using neurotransmitters launched in synapses.
Action potentials are brought about with the aid of using membrane depolarization to threshold.
The depth of a stimulus is regularly encoded withinside the charge of movement potentials produced with the aid of using the sensory receptor. Thus, an extreme stimulus will produce a extra fast educate of movement potentials, and decreasing the stimulus will likewise gradual the charge of manufacturing of movement potentials.
