X, Y, and Z are adjacent sensory receptors in the skin. During administration of the flu shot, a needle is inserted in the middle of Y's receptive field. All three receptors are activated. Which of the following is likely to be true?
A) The receptor potential in neurons X and Z will be more depolarized than in neuron Y.
B) It won't be possible to discriminate which neuron's receptive field was stimulated at its center.
C) The frequency of action potentials in the afferent pathway from neuron Y will be increased by excitatory interneurons projecting from the afferent pathways from neurons X and Z.
D) The frequency of action potentials in neuron Y will be greater than that in neurons X and Z.
E) The receptor potentials in all three neurons will achieve the same, average value.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

explanation:

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
