Scores on neuropsychological tests show amount of damage done to person Destruction and Stimulation test: can destroy parts of the brain to see effect or stimulate nerves with electrodes (Dr. Penfield- famous neuroscientists) – mapped motor and sensory areas Broca’s aphasia: could understand, but not speak Dorsal Stream: action (D.A) Ventral Stream: perception (V.P) Single-…
Neurons: constructive unit of the nervous system; interconnected like electrical circuits Made up of: Soma (cell body): contains nucleus, keeps nerve cells alive (grey matter) Dendrites: receiving portion of nerve cell- receiving end of cell Axon: sends impulses away from the cell (white matter) Dendrites and axons are all interconnected; vary in shape and size…

Once the ideas of Planck and Einstein (re: quanta) had been accepted, the study of atomic and molecular structure began. With the invention of the spectroscope (Bunsen & Kirchhoff, Fig 2/175) the quantitative analysis of the atomic spectra of elements began. The range of frequencies of light emitted or absorbed by an atom is called…
Isotopes have the same number of protons, but different numbers of neutrons. This means that while the atomic number of an element will NEVER change…The MASS of the atom can change quite a bit depending on how many neutrons there are The number of protons in an atom is also called the “atomic number”. This…
After reviewing the Bohr-Rutherford diagram you should know that atoms wish to “fill” electron orbits. Atoms tend to combine in a way that allows the resultant compound to be neutral but have only full electron orbits on the atoms. Lets do an example: Note: I draw the electrons with holes in noticeable places. In reality…
Latitude o imaginary lines that measure the distance north or south of the Equator (0°) o lines are parallel to the Equator at regular intervals (approximately 113 kilometres apart) What is Latitude? Its reference point is the equator. The equator’s latitude is O degrees. Even though the lines run horizontally, latitude measures north and south.…
Minerals are non-renewable resources found all over the world The Canadian Shield is the source of many of our mineral deposits Minerals can be divided into three groups: Metallic (copper, nickel, uranium, gold, etc) Fossil Fuels (coal, oil, natural gas) Industrial (stone, diamonds, salt, potash) Environmental Issues Mining can cause air pollution, acid precipitation, and…
Softwood Forests: coniferous trees (cone-bearing: fir, pine, spruce) make up 66% of Canada’s forests Hardwood Forests: deciduous trees (lose leaves every year: birch, maple) make up 12% of Canada’s forests Commercial Forests Trees are harvested to make a profit exists in warmer, wetter areas where trees grow quickly British Columbia, Alberta Non-commercial Forests Not profitable…
There are five major agricultural production sectors in Canada. They are….. grains & oilseeds (wheat, oats, rye, flax seed, canola, soybeans, and corn ) 34% red meats (beef, hog, veal, lamb) 27% dairy 12 % horticulture 9% poultry and eggs 8% Horticulture, poultry & eggs, and dairy are all produced with a domestic orientation –…
Key Terms Aboriginal Peoples: Descendents of Canada’s original inhabitants Treaty: An official agreement between the federal government and the First Nations – Aboriginal people give up their land rights (except for reserves) and accept treaty money/government assistance Reserve: Area of land set aside for status Indians Assimilate: To lose your culture and adopt the culture…
Definition An eating disorder characterized by the refusal or inability to eat which creates a state of self-starvation. Characteristics Victims have a severe distortion of body image and extreme concern about appearances. Use voluntary starvation, excessive exercise and diet pills to try and achieve idealized body proportions. Have an obsession with food and calories. Physical…
Attempting to enter the basic American search for self-control, individuality and thinness has not brought most people more health and happiness. Instead, we often feel as if we have failed and the blame is laid squarely on our shoulders. But the social requirement that we achieve the “ideal weight” is based on the presumption that…
Dihybrid cross = involves inheritance of 2 characteristics Example 1: In Pisum sativum, a round seed is produced by a dominant allele (R), while wrinkled seeds are produced by the recessive allele (r). Yellow seeds are produced by the dominant allele (Y), while green seeds are produced by the recessive allele (y). In a cross…
Niche An organism’s ecological ROLE in the environment (NOT HABITAT!) All components of lifestyle and how they affect other organisms Three Types of Symbiosis Mutualism both species benefit Commensalism one species benefits, the other is unaffected Parasitism one species benefits, the other is harmed Lichen Lichen is really two organisms: algae and fungus. The fungus…
Characteristics of Life Living things are organized. Living things are made up of cells. Living things metabolize. Living things maintain an internal environment. Living things grow. Living things respond. Living things reproduce. Living things evolve. Seven Levels of Taxonomic Classification Kingdom Phylum Class Order Family Genus Species Kingdom Animalia Characteristics All animals are multicellular, eukaryotic…
Mycology Myco- = fungus -ology= study of General Characteristics of Fungi: Eukaryotic Decomposers – the best recyclers around No chlorophyll – non-photosynthetic Most multicellular (hyphae) – some unicellular (yeast) Non-motile Cell walls made of chitin (kite-in) instead of cellulose like that of a plant Are more related to animals than the plant kingdom Lack true…
The largest animal phylum- 1 million species of crabs, shrimp, spiders, scorpions, and insects make up this phylum Have jointed appendages; segmented bodies Exoskeletons made of chitin Molt; have heads with many sensory organs. Bilateral Simple and complex eyes that detect only light intensity and form images Antennae that smell chemical substances in the environment…
Introduction: Surface tension refers to water’s ability to “stick to itself”, due to the forces of cohesion. Surface tension can be measured and observed by dropping water (drop by drop) onto a penny. The number of water drops that can fit on a penny will surprise you. Initial Observation: Observe surface tension by seeing how…
Background: As members of the class Amphibia, frogs may live some of their adult lives on land, but they must return to water to reproduce. Eggs are laid and fertilized in the water. On the outside of the frog’s head are two external nares, or nostrils; two tympani (tympanic membranes), or eardrums; and two eyes,…
