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

generalized eukaryotic plant cell. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Plants are unique among the eukaryotes. The interiors of plant cells‚ like all eukaryotic cells‚ contain numerous organelles‚ which are membrane bounded structures that close off compartments within which multiple biochemical processes can proceed simultaneously and independently. The cell membrane of the plant cell has a phospholipid

light used for photosynthesis requires a specific wavelength for the pigments in chloroplast to absorb it. Light independent reactions occur in the stoma of the chloroplast whereas the light reactions occur in chloroplasts that sit on the thylakoid membrane. White light is comprised of all the colors in the spectrum where each of these colors contains different energy; hence they are all of different wavelengths. Since pigments only absorb certain wavelengths within the visible spectrum‚ the others

chloroplasts of plant cells where CO2 + H2O + Sunlight C6H12O6 + O2. The chloroplasts use light‚ an electromagnetic energy source‚ to produce food for the plant in the form of sugar molecules. During photosynthesis‚ the excited electrons from the light pass through proteins in the electron transport chain (ETC)‚ where ATP and NADPH are produced. The CO2 absorbed by the plant are then fixed into carbohydrates by these two organic molecules (Hoober 1984; Halliwell 1984). It is currently known that plants do not

Heat on the pH of the Vegetable and Their Pigment PURPOSE The purpose of this experiment is to see how pH levels of certain vegetables change while being cooked in four different mediums (frying‚ boiling‚ steaming‚ roasting)‚ and how the varying pH levels change the coloring of the vegetables. We will analyze how the different method of cooking/heating changes the levels of pH. BACKGROUND INFORMATION This experiment is based around the different pigments in vegetables‚ of which we researched and

process where plants use sunlight (energy) to synthesize foods forming the products carbohydrates and water (H20 + CO2 + Light CH2O + O2). For photosynthesis to take place they need water‚ carbon dioxide and light and chloroplasts. Light is absorbed inside he thylakoid membrane of the chloroplasts‚ and the carbohydrate reaction or synthesis takes place in the stroma. In plants there are five kinds of chlorophylls with the same basic structure‚ chlorophylls occur as greenish pigments and capture light

Introduction Photosynthesis takes place in the chloroplast and is the use of sunlight energy for cell processes. It happens through a number of chemical reactions and the transfer of electrons. It is used as the source of energy (ATP) for plants. The reaction equation for photosynthesis is H2O + CO2 + (Light) (CH2O)N + CO2 In the Hill reaction‚ Robert Hill showed how chloroplasts in water can still function if there is light and an electron acceptor to release oxygen. He proved that the oxygen

Temperate forests correspond to forest concentrations formed in the northern and southern hemisphere‚ or in temperate regions. Main characteristics include: wide leaves‚ large and tall trees and non seasonal vegetation. Temperate forests can be further distinguished by weatherpatterns and geographical features that favor the predominance of certain kinds of trees. In temperate coniferous forests‚ evergreen coniferspredominate‚ while in temperate broadleaf and mixed forests‚ a more even distribution
