PLZ H MMM I NEED THE ANSWER NOW Carolyn observed a freshwater plant, Elodea, in a small aquarium filled with freshwater on her desk. In one five-minute period, Carolyn counted 32 bubbles that formed on the plant’s leaves and were released into the water. She then moved the aquarium from her desk to a sunlit window and observed the Elodea again. In a second five-minute period, Carolyn observed 194 bubbles form and be released by the Elodea into the water.

a) What gas is released in this investigation?­­

b) Describe how the bubbles released by the Elodea signify that the plant is cycling matter. Provide evidence to support your answer.

c) Explain why the number of gas bubbles produced by the Elodea in a five-minute period increased when the aquarium was moved from the desk to the sunlit window.

Bubbling Plants Experiment to Quantify Photosynthesis

Photosynthesis

Explanation:

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
