Answer:
D: a trait with a dominant and recessive allele!
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.
The correct answer is Soluble phosphorous
Soluble phosphorus is a measure of orthophosphate (PO4), the
soluble and inorganic filterable fraction of phosphorus, which is the most
stable type of phosphate and it is the form directly used up by the plant
