Anatomical or molecular homologous structures
You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. You only need small amounts of trace minerals.
B - Homozygous, because both alleles are the same
Answer:
Neurotransmitters
Explanation:
Neurotransmitters are the chemicals that are released from the axon terminals of the pre-synaptic neurons of the synapse. These chemicals have receptors at the surface of the dendrites of postsynaptic neurons of the synapse. Binding of neurotransmitters to their receptors brings about the excitatory or inhibitory effect on the postsynaptic neuron. Accordingly, the action potential is fired. In this way, electrical signals are passed from one neuron to the next at the synapse. Acetylcholine is an example of neurotransmitters.
