What substance is released by the nervous system and excites muscle cells?
Calcium
The Lewis electron dot system represents electrons in the -?
outer energy level
Which electrons has the most energy in an atom?
The energy level that holds a maximum of 8 electrons holds the most energy because 8 electrons = maximum stability so it takes more energy to break away an electron. The energy level that holds a maximum of 8 electrons holds the most energy because 8 electrons = maximum stability so it takes more energy to break away an electron.

What is the molecule responsible for chemical reactions?
The cell itself is responsible for chemical reactions. Chemical reactions are the basis of life, and all parts of the cell work together to make them happen. Specifically the enzyme and mitochondria are often cited as being responsible. The enzymes are proteins that create a binding surface for the chemical reaction and speed the process. The mitochondria act as a digestive system and energizer for the cell.

Where do electrons get their energy from in photo system II?
PSII is a protein that is filled with chlorophyll, specifically P680. This chlorophyll captures the energy of light (light that has a wavelength of 680). That energy is used to split a water molecule into O2 and a hydrogen ion (an electron) and excites that electron that is then passed down the electron transport chain to PSI (filled with P700) where the energy in the light of the wavelength of 700 is used to excite it further.

What would happen if i don't water my bean plants as often as i should?
They would not be able to preform photosynthesis efficiently. Water is split to replace electrons raised to a higher energy level from the chlorophyll pigment as it gives it's electrons on to photo system II. Water replaces these electrons by being split. Without enough water this process, which makes glucose for the plant to build and use for energy, would be slowed considerably.

What converts sunlight into sugars?
Photosynthesis that is where The energy-fixing reaction of photosynthesis begins when light is absorbed in photosystem II in the thylakoid membranes. The energy of the sunlight, captured in the P680 reaction center, activates electrons to jump out of the chlorophyll molecules in the reaction center. These electrons pass through a series of cytochromes in the nearby electron-transport system. After passing through the electron transport system, the energy-rich electrons eventually enter photosystem 1. Some of the energy of the electron is lost as the electron moves along the chain of acceptors, but a portion of the energy pumps protons across the thylakoid membrane, and this pumping sets up the potential for chemiosmosis. The spent electrons from P680 enter the P700 reaction center in photosystem I. Sunlight now activates the electrons, which receive a second boost out of the chlorophyll molecules. There they reach a high energy level. Now the electrons progress through a second electron transport system, but this time there is no proton pumping. Rather, the energy reduces NADP. This reduction occurs as two electrons join NADP and energize the molecule. Because NADP acquires two negatively charged electrons, it attracts two positively charged protons to balance the charges. Consequently, the NADP molecule is reduced to NADPH, a molecule that contains much energy. Because electrons have flowed out of the P680 reaction center, the chlorophyll molecules are left without a certain number of electrons. Electrons secured from water molecules replace these electrons. Each split water molecule releases two electrons that enter the chlorophyll molecules to replace those lost. The split water molecules also release two protons that enter the cytoplasm near the thylakoid and are available to increase the chemiosmotic gradient.

Where from permanent magnet get energy?
Permanent magnets don't get energy from anywhere. The nature of the atoms a natural magnet is made of allow for the free exchange of electrons with other objects that also have free electrons. Energy is conserved in the system, not used and so a natural magnet doesn't need power to operate.
Why do metals conduct heat and electricity?
Electrons in metals are mobile and carry (conduct) electricity and heat energy. Plato: Free moving electrons carry both heat and electric current throughout the system
What substance excites the nervous system?
The nervous system responds to stimuli, that is referred to as excitability. The chemicals that are involved in carrying the impulse from being excited are called neurotransmitters.
