She should make observations next.
If she doesnt make observations, it would be difficult to form a hypothesis and design an experiment, the result will more likely to be inaccurate too.
Answer:
3 molecules of water and use glycerol and fatty acid reactants
The correct answer is: prevent reception of a signal in a receiving neuron
Neurotransmitters are signal molecules or chemical messengers which transmit signals across a chemical synapse. Neurotransmitters send the signal, from one neuron (nerve cell) to another neuron, from neuron to muscle cell (motor plate), or from neuron to gland cell.
Drugs that bind to neurotransmitter’s receptor can have two effects on its action:
• Antagonists-they bind to receptor and thus prevent a neurotransmitter from binding to it
• Agonists-they bind to receptor and mimic the normal neurotransmitter (have the same effect as neurotransmitter).
Some plants have a complex life cycle that includes the sporophyte and,gametophyte stages.
