- Give typing answer with explanation and conclusion A biologist is measuring photosynthesis and respiration in a lake. She places a pair of bottles in the lake and measures the initial oxygen concentration to be 9.56 mg O2/L. Twenty-four hours later, she measured the oxygen concentrations in the light and dark bottles: 8.23 mg O2/L in the dark bottle and 10.11 mg O2/L in the light bottle. Calculate the hourly rates of NPP and respiration for this ecosystem. Be sure the units are correct. A) NPP=0.0229 mg O2/L/h, R=0.0554 mgO2/L/h B) NPP=.55 mgO2/L/h, R=1.33 mgO2/L/h C) NPP=-0.0554 mgO2/L/h, R= -0.0229 mgO2/L/h D) NPP=0.0229 mg O2/L, R=0.0554 mgO2/LLight that the chlorophyll-a pigment uses may be measured by the solar-induced fluorescence (650-850nm). This fluorescence caused by the sun and a plant's gross primary output are correlated linearly. Why does this reasoning shows that solar induced fluorescence can be used to infer net photosynthesis?Light that the chlorophyll-a pigment uses may be measured by the solar-induced fluorescence (650-850nm). This fluorescence caused by the sun and a plant's gross primary output are correlated linearly. Why can solar induced fluorescence be used to infer net photosynthesis?
- Solar-induced fluorescence can be used to infer net photosynthesis. This is because this solar-induced fluorescence is able to measure the light that is used by the chlorophyll-a pigment (650-850nm). There is a linear relationship between this solar-induced fluorescence and the gross primary production of a plant. How does measuring chlorophyll-a pigment with solar-induced fluorescence help us infer net photosynthesis?How were the investigators able to identify potentialsentinel plants that were starting to experience phosphorousdeficiency?Use to answer Household chemicals are sometimes discarded in ways that allow the chemicals to enter lakes and streams. These diluted chemicals may affect the growth of aquatic plants or terrestrial plants growing beside the water. A student hypothesized that a particular household chemical would have a negative effect on the photosynthetic rate of plants. She assumed that the chemical would not kill the plants. Question: Unit C - Design an experiment to determine whether a household chemical affects the rate of photosynthesis in plants . Your response should include • a detailed procedure • identification of the controlled, manipulated, and responding variables • an explanation of evidence that you will collect and how it will be interpreted to determine the effect the chemical had on rate of photosynthesis

What will be a suitable hypothesis predict answers for the following: A) what is the rate of germinating peas versus non-germinating peas. B) what is the effect of temperature on germinating peas?What are the potential advantages of promoting artificial photosynthesis research?the leaf was treated with iodine solution. 2.5 Explain the results observed in Question 2.4. C Question 3 B.1 Photosynthesis is the only process that is able to combat the greenhouse effect. Explain why. 2 Photosynthesis is said to be the most important process on Earth.
