Good Luck! Hope I wasn't too late.
Solar energy provides the reducing power within green leaves to convert CO2 and H2O into sugars. ... During illumination, leaf cells have both a source (respiration) and sink (photosynthesis) for CO2. Respiration in some species appears to be greatly stimulated by light.
The two are potassium and rubidium. Why? Na is an alkali metal. As you go down the metals become more reactive.
Calcium has 20 protons. Why? The atomic # is 20 (the one at the top).
It has 20 neutrons. Why? The atomic mass (the number on the bottom) is ~40, ignoring electron mass. 40- 20 protons = 20 neutrons.
It has 20 electrons.
Why? The # of protons and electrons is the same. Ions aren't on the periodic table.

<span>The answer is nuclear imaging. A subject is asked to take in a radionuclide (radioactive
isotopes) and as the radioactive material passes though the body, it continually emits radiation that is detectable by an instrument such as a gamma camera. Examples of nuclear imaging
techniques are SPECT and PET.</span>
