<span>The concentration of carbon dioxide, water supply, and the temperature are the other factors needed for photosynthesis. Light seems to be a limiting factor, when too low photosynthesis is declined. Given too much though may also slow the rate of photosynthesis due to the bleaching of chlorophyll.</span>
Answer:
1.Ions
2. Neurotransmitter
Explanation:
The neurons transmit the signals in the form of the electrical form and the chemical form.
The electrical signals are generated in the neurons as a result of the flow of ions or electrically charged species to maintain the equilibrium.
The signal from one neuron to another neuron takes place in the form of the chemical signal that is the chemical stored in the terminal of the axon called neurotransmitters.
Thus, ions and neurotransmitters are correct.
creates the sun's energy from nuclear reactions
sorry if wrong.
