What important gas do we take is when we breathe? - Oxygen What important gas we breathe out? - Carbon dioxide When the water turns blue, which gas is it most common? - O2(oxygen) When the water turns yellow, which gas is most common? - CO2( carbon Dioxide) What does it tell you when the water is green? - There is an equal amount of o2 &CO2.

how does light intensity affect oxygen production - up to 40% increasing the light intensity increases the oxygen production. Beyond 40% there is no effect. how does temp affect oxygen production - oxygen production is maximized around 25 degrees Celsius. Oxygen production goes down when temp is too hot or too cold. --- to much CO2 (hot) is bad and enzymes are stunted when too cold how does carbon dioxide levels affect oxygen production - up to about 300-400ppm, increasing carbon ...

Atom - The basic unit of matter. An atom is the smallest particle of the element that still has all the properties of the element. Atoms are made up of smaller particles called protons, neutrons, and electrons. the smaller electrons orbit around a central nucleus of protons and neutrons. Atomic Number - The number of protons in the nucleus of an atom. Elements are distinguished from one another by their atomic numbers. For example, any atom with 2 protons is an atom of helium. The...

Which of the following statements is true concerning the neuromuscular junction? The NMJ terminates on a muscle fiber. What prevents continuous stimulation of a nerve synapse and how is this accomplished? The short existence of neurotransmitters in the synapse prevents continuous stimulation. Some synapses contain enzymes that rapidly inactivate neurotransmitters and other synapses rapidly absorb the neurotransmitter. What neurotransmitter is found at the neuromuscular junctions? Acetylchol...
