Explanation:
Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.
Food was cooked, quickly frozen, and then dehydrated in a special vacuum chamber. Freeze-dried food didn't need to be refrigerated and would last a long time. To make most freeze-dried foods, astronauts squeeze water into the food packages and then eat the food after it absorbs the water.
Explanation:
Receptors = Sensory neurons
Relay = Relay neurons
Effectors = Motor neurons
Cell bodies of sensory neurons are only found in the root ganglion. (F)
Cell bodies of relay neurons are only found is the grey matter of the spinal cord. (G)
Cell bodies of motor neurons are also found at G.
Hence the answer is Option D.
