Taste bud receptors if not stimulated are normally polarized. With the presence of the food, chemicals from the food bind with the cell protein which depolarized the cell membrane receptor. Depolarization will lead into the propagation of electric impulse. This will lead into the creation of sensory impulse. The larger number of the chemicals in the food will lead into a stronger impulse.
D) yes because in order to inherent a recessive trait you would have to have two recessive genes. In this case it’s (gg)
E)Yes because the parents have the genes (Hh) and (hh). (I’m assuming based off the first question) Therefore, if an offspring has hanging earlobes there’s a 50% chance they’d have the genes (Hh)
