  • adu evans Question
    Explain how the carbon in a molecule of CO2 produced in the tissue of a living mammal may ultimately be found in the underground food storage organ of a named plant.
    29 August 2013Comment
    • andy chuks I have a faint idea, when a living mammal respires it produces CO2 while taking in O2, this CO2 utilized by plant in a process called photosynthesis, to produce food and O2. Check out Photosynthesis for more details.

    02 February 2013Comment
    • andy chuks Movement in Amoeba is accomplished by protrusion of cytoplasm of the cell involving the formation of pseudopodia. The cytoplasm slides and forms a pseudopodium in front to move the cell forward. This type of movement has been linked to changes in action potential; the exact mechanism is still unknown. Locomotion of amoeba occurs due to the sol-gel... Read All
