Heterotroph
an organism requiring organic compounds for its principal source of food.
Cellular Respiration
the oxidation of organic compounds that occurs within cells, producing energy for cellular processes.
Control Group
a group in an experiment that does not receive experimental treatment.
Experiment
a planned procedure to test a hypothesis.
Dependent Variable
variable that is measured in an experiment.
Eukaryotic
any organism having as its fundamental structural unit a cell type that contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing genetic material organized into chromosomes, and an elaborate system of division by mitosis or meiosis, characteristic of all life forms except bacteria, blue-green algae, and other primitive microorganisms.
Imprinting
learning that can occur only during a specific period early in the life of an animal and cannot be changed once learned is called imprinting.
Carbon Dioxide Fixation
Carbon dioxide is fixed to ribulose-diphosphate. This reaction is catalysed by the enzyme carboxy-dismutase and gives 2 molecules of phospho-glycerin acid. This compound is then reduced by NADPH, by means of the energy of ATP, to give triose phosphate.
Diffusion
the spreading of something more widely
Membrane
a pliable sheet like structure acting as a boundary for an organism.
Biodiversity
number of different things in one habitat.
ATP
an ester of adenosine and triphosphoric acid, C10H12N5O4H4P3O9, formed esp. aerobically by the reaction of ADP and an orthophosphate during oxidation, or by the interaction of ADP and phosphocreatine or certain other substrates, and serving as a source of energy for physiological reactions, esp. muscle contraction.
NADH
an abbreviation for the reduced form of NAD in electron transport reactions.
Pie graph
a pie graph is a graph in a circular shape with information divide up upon the circle.
Bar graph
a bar graph is a graph using a grid that has labels on each side to explain the graph.
Photosynthesis
The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.
Enzyme Catalyzes
a particular type of chemical reation.
Krebs Cycle
a cycle of enzyme-catalyzed reactions in living cells that is the final series of reactions of aerobic metabolism of carbohydrates, proteins, and fatty acids, and by which carbon dioxide is produced, oxygen is reduced, and ATP is formed.
PH
measure of the acidity of a solution representing the hydrogen ion concentration.
Autotroph
any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists.
Learning
the development of behaviors through experience is called learning.
Carotenoid
any of a group of red and yellow pigments, chemically similar to carotene, contained in animal fat and some plants.
Chlorophyll
the green coloring matter of leaves and plants, essential to the production of carbohydrates by photosynthesis, and occurring in a bluish-black form, C55H72MgN4O5 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).
Community
many different species in one habitat.
Reasoning
the ability to analyze a problem and think of a possible solution is called reasoning.
Fermentation
The anaerobic conversion of sugar to carbon dioxide and alcohol by yeast.
Prokaryotic
An organism of the kingdom Monera (or Prokaryotae), comprising the bacteria and cyanobacteria, characterized by the absence of a distinct, membrane-bound nucleus or membrane-bound organelles, and by DNA that is not organized into chromosomes
Functions
an activity or structure.
Observation
the act of noting or perceiving objects or events using the since.
Electron Transport Chain
The oxidation of NADH occurs in a stepwise manner involving an electron transport chain. Reducing equivalents go via a series of carriers to oxygen. Electrons flow downhill, energetically. Energy released in this process is used to generate the Proton Motive Force which is used by the cell to make ATP.
Enzymes
are proteins that act as biology catalysts with in the cells of all living organisms.
Line graph
a line graph is a graph where plot on a sheet of paper going in a line that is mainly for explaining increasing and decreasing matters.
Calvin Cycle
a cycle of biochemical reactions taking place in the chloroplasts plants during photosynthesis in which carbon dioxide is fixed and six-carbon sugar formed;
NADPH
The reduced form of NADP.
Abiotic
the physical aspects of its habitat.
Aerobic
Living or occurring only in the presence of oxygen: aerobic bacteria.
Anaerobic
An organism, such as a bacterium, that can live in the absence of atmospheric oxygen
Innate Behavior
genetically-programmed behavior is called innate behavior
Subtrant
specific meaning that each enzyme fis with only a single type of reactant molecule.
Theory
explanation based on a se of related hypothesis that have been tested and confirmed many times.
Thylakoid
a flattened sac or vesicle lined with a pigmented membrane that is the site of photosynthesis, in plants and algae occurring in interconnected stacks constituting a granum of the chloroplast, and in other photosynthesizing organisms occurring either singly or as part of the cell membrane or other structure.
FADH2
is another type of electron carrier.
Hypothesis
a proposed explanation for an observation that can e tested by additional observations or experimentation
Independent Variable
factor that is varied in an experiment.
Glycolysis
An ATP-generating metabolic process that occurs in nearly all living cells in which glucose is converted in a series of steps to pyruvic acid.
Prediction
A thought or what you think
Habitat
population were species live.
Pigment
any substance whose presence in the tissues or cells of animals or plants colors them.
Ecosystem
ecological system.
Fixed Action Patterned Behavior
the off spring will do as the parent without being taught this is called fixed action patterned behavior.
Conditioning
a more complex type of learning is conditioning.
Behavior
behavior is an action or series of actions performed by an animal in response to a stimulus
