The incorrect among the choices is "<span>direct signaling involves the activation of g proteins"
This is incorrect because direct signaling does not involve the activation of g proteins rather it involves the activation of ion channels resulting to either an excitation reaction (depolarization of the membrane) or an inhibition reaction (hyperpolarization of the membrane); and this will ultimately affect the action of the organ the nerve is innervating.</span>
<span>A low level of TSH is indicative of hyperthyroidism. This is a medical condition in which the thyroid gland secrets or produces an excess of hormones resulting in an imbalance.

Answer:
D. Particle A orbits the nucleus, and Particle B is located in the nucleus
Explanation:
Here since both particles are of the same atom and particle A is much lighter we can infer that Particle A is electron because electrons are much lighter than protons which are Particle B in this case. Thus, particle A orbits nucleus as an electron does and particle B is in nucleus where protons are.
