Radioactive - The atoms decay over time and emit radiation. Isotope - The same number of protons, but a different number of Neutrons. Ionized - The number of electronic do not equal the number of protons. Atom - The basic unit of a chemical element. Atomic number - the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table. Electron - a stable subatomic particle with a charge of nega...

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 ...

Using the Gizmo, a student types the word "teaching" four times, recording times of 45.1, 24.4, 19.6 and 14.8 seconds, in that order. Which of the following is the most likely explanation of these results? - The student tried the same type of test four times. A student sets up an experiment according to the table below. What question was the student most likely investigating? - What test is the hardest to adapt to?

Based on the diagram below, rank three objects from least dense to most dense. - object X, object Y, object Z fill in the blank: an object is most likely to sink in water if? - it has a high density A ball has a mass of 33.6 grams and a volume of 14.0 cubic centimeters (cc). What is its density? - 2.4g/cc Three balls were measured and placed in a liquid. Based on the following data, what could be the density of the liquid? - 0.9 g/mL "That's just the tip of the iceberg...
