I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:
You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled
If you are crossing rr with an Rr (so a heterozygote wrinkled):
50% will be Rr (wrinkled)
50% will be rr (round)
See my picture for the Punnett Squares for both answers!
Answer:
The correct answer is -
A. axon
B. dendrite
C. neurotransmitter
D. Synapse
Explanation:
The given diagram is the representation of two neurons connected by the chemical signal. Each neuron has a nerve fiber that carries the nerve signal from one neuron to another covered with sheath, this body is called Axon.
Axon is connected with dendrite, which receives a signal from other neurons and is arise from the cell body of neurons in various numbers. The site where two neurons meet called synapse which is releases neurotransmitters a chemical signal molecule.
