up with an explanation of what had just occurred‚ they felt a strong pull. This pull came from Cactus pear Opuntia Ficus-indica. Opuntia was ready to perform photosynthesis and nothing was going to stop her from using the friends of Carla and Carla. Without hope‚ Carla and her friends were unable to escape the cactus desires. Photosynthesis in Opuntia does not work the same way as in C3 plants because Opuntia is a CAM plant. Opuntia lives in a deserted region where it is hot and dry. Thus‚ Opuntia

follows the Northern Hemisphere’s growing season. The Northern Hemisphere dominates the annual cycle of CO2 concentration because it has much greater land area and plant biomass than the Southern Hemisphere. Concentrations peak in May as the Northern Hemisphere spring green up begins and reach a minimum in October when the quantity of biomass undergoing photosynthesis is greatest. So basically‚ more CO2 is created when the sun is directly giving light to the vegetation. Half of the year the sun is more

respiration also produces CO2‚ H2O and Heat. This is an organic redox reaction. Redox reactions Redox reaction occur when there is a movement of electrons between atoms. Part of a redox reaction include: Oxidising Agent: Atom losing/giving away electrons (causing reduction) Reduction: Atom that gained/received the electron from the oxidizing agent‚ making it more negative and thereby the name reduction/reduced. Reducing Agent: Atom that will be taking electrons

SCI203 Phase 3 Lab Report Sources of CO2 Emissions Sharon Patton June 8‚ 2015 Colorado Technical University Purpose The purpose of this report is to determine the increase or decrease in CO2 emission over the past 40 years. Showing that human activity is the reason for the altering of the CO2 emissions to the earth. Resulting in the unbalancing of ecosystems across the globe. (M.U.S.E.‚ 2010) Introduction Carbon dioxide is naturally present in the atmosphere as part of the Earth ’s
Free Carbon dioxide Global warming
to consider is what the cause of global warming is‚ and the answer to this basic question is greenhouse gases. Greenhouse gases are natural gases such as CO2‚ Nitrous Oxide or Methane and are created in one of two ways. The first way is‚ through natural cycles‚ for instance‚ CO2 is released through animal respiration or plant photosynthesis. The alternative greenhouse gas production comes from man’s use of different fuels and products; this can lead to anthropogenic climate changes. Anthropogenic

its ability to remove nutrients and toxins from water sources. Thus‚ duckweed will kill the organisms that require similar nutrients‚ yet aid the organisms that would otherwise die to toxins. Specifically‚ if one was to place Elodea plants in a tank with duckweed‚ then the Elodea will die due to the lack of nutrients from the duckweed having used the nutrients for its own benefits. Furthermore‚ if one were to place an organism such as Daphnia in a tank with Duckweed‚ then the duckweed would remove any

I) Introduction In this lab‚ a test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively
