Passage 1 (1) An upsurge of new research suggests that animals have a much higher level of brainpower than previously thought. If animals do have intelligence‚ how do scientists measure it? Before defining animals’ intelligence‚ scientists defined what is not intelligence. Instinct is not intelligence. It is a skill programmed into an animal’s brain by its genetic heritage. Rote conditioning is also not intelligence. Tricks can be learned by repetition‚ but no real thinking is involved. Cuing

"nourishing") or "producer"‚ is an organism that produces complex organic compounds (such as carbohydrates‚ fats‚ and proteins) from simple substances present in its surroundings‚ generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis). * Photosynthesis (pron.: /foʊtoʊˈsɪnθəsɪs/; from the Greek [photo-]‚ "light‚" and [synthesis]‚ "putting together"‚ "composition") is a process used by plants and other organisms to

energy. 9. Explain how C4 photosynthesis is based on a spatial arrangement of structures‚ whereas CAM photosynthesis is temporally based. C4 photosynthesis is based on a spatial arrangement of structures because in C4 plants‚ light and carbon reactions are separated into different cells. The light reactions along with a carbon-fixation reaction occur in mesophyll cells‚ but the Calvin cycle occurs in the inner ring of bundle-sheath cells. However‚ CAM photosynthesis is temporally based because

Cytoplasmic streaming is controlled by microfilaments in the cell’s cytoskeleton. These filaments of actin and myosin move cellular contents in an active process that uses energy released by breaking ATP down in ADP. How might a cell benefit by

1. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. To start off with we will need to define photosynthesis and respiration. Photosynthesis is a process in which carbon dioxide‚ water‚ and certain inorganic salts are converted into carbohydrates by green plants‚ algae and certain bacteria using energy from the sun and chlorophyll (dictionary.com). Respiration is all of the physical and chemical processes in an organism by which oxygen

Premium Photosynthesis Carbon dioxide Light
The Calvin Cycle Plants use energy from the sun in tiny energy factories called chloroplasts. Using chlorophyll in the process of photosynthesis‚ they convert the sun’s energy into storable form in ordered sugar molecules such as glucose. In this way‚ carbon dioxide from the air and water from the soil in a more disordered state are combined to form the more ordered sugar molecules. Carbon dioxide is captured in a cycle of reactions known as the Calvin cycle or the Calvin-Benson cycle after
