curved wings : t

smooth eyes are dominant to sparkling eyes

let smooth eyes = H

spark ling eyes = t

tan body is dominant to ebony body color.

Let ebony color be t

If flies that are heterozygous for all three traits are crossed;

we have HtHtHt × HtHtHt

Then the selected trihybrid traits for the cross will be (HHH,HHt, HtH, Htt, tHH, tHt, ttH, ttt)

We will realize that from the punnet square in the diagram below, the proportion of the offspring would you expect to be heterozygous for all three traits (i.e HtHtHt) is asterisk in the punnet square and will be \frac{8}{64}

= \frac{1}{8}

Ed was in a bicycle accident, he had no sensations in his injured leg. He can move the limb normally. Based on the functional cl
____ [38]
There are two types of neurons in our legs: motor neuron and sensory neuron. These send and receive messages to and from each other and the brain.  

After Ed's accident, he can't move his injured leg since the motor neuron is dysfunctional. The sensory neuron is functional so he can feel his limbs but can't move them since when the sensory neuron sends a message to the motor neuron, it isn't able to deliver the message to the brain to make the leg move. This is why he can still feel his limbs but is not able to move them.
