Feel like everyone’s always yelling at you for not doing what you’re supposed to be doing? Look, this is your life, and you need to get in charge of it if you don’t want everyone making decisions for you. I teach parents how to advocate for their kids, but I also teach kids how to…
There a 6 essential features needed to create maps. – MUST HAVES Title: A title should tell the reader both what the map is about and where the map is depicting. It should be located at the top of a map, in large print, inside the border of the map. eg. Land Use in Mississauga,…
Incomplete Dominance – there is an interaction between 2 alleles in the homozygous form – alleles are semi – or incompletely dominant and act together to yield an intermediate heterozygote – usually phenotypically between the two homozygote Codominance – when definite product or substance controlled by each allele is identified ex. of incomplete dominance: Andalusian…
The polymerase chain reaction is a technique for quickly “cloning” a particular piece of DNA in the test tube (rather than in living cells like E. coli). Thanks to this procedure, one can make virtually unlimited copies of a single DNA molecule even though it is initially present in a mixture containing many different DNA…
– inhale – oxygen travels down the bronchi and bronchioles – into the alveoli – oxygen strikes the moist coating of the alveolar wall – dissolves in this liquid – moves by diffusion through the cells of the alveoli, and into the cells of the capillaries – enters the red blood cells which will transport…
Asthma – results in contraction of smooth muscle that surrounds airways – makes breathing difficult – allergic reaction – treat with bronchodilators – causes airways to dilate (increase in diameter) Bronchitis – inflammation of bronchial lining + overproduction of mucous and frequent coughing – related to smoking and other irritants (air pollution etc) – increased…
Pathogen – a disease causing organisms – May be: – viral (HIV, chicken pox) – bacterial (TB, strep) – fungal (athletes foot) – Protozoan (malaria = plasmodium) – Flatworm – Roundworm How to get infected? – airborne; waterborne; food; insect transmission; STI; skin Barriers to infection – skin, mucous membranes Specific defenses – production of…
Evolution describes the changes in the gene pool of a species over time. These changes are the results of mutations, natural selection and genetic drift. Often populations produce more offspring than the environment can support; in other words, they often exceed the carrying capacity. Over-production of offspring leads to intraspecific competition and survival of the…
Genetics Definitions Genes: portion of the DNA molecule that codes for a particular protein. Loci: location in the DNA molecule of the gene Alleles: forms of a gene Homozygous: paired alleles are identical Heterozygous: paired alleles are different Genotype: set of all alleles (i.e. genetic expression) Phenotype: all observable traits (i.e. physical expression) Genome: The…
A summary is a concise version of an original text. What is a good summary? 1. A good summary should give an objective outline of the whole piece of writing. It should answer basic questions about the original text such as “Who did what, where, and when?”, or “What is the main idea of the…
Deterrence theory contains principles about justice which many of us find attractive because it conforms to what we recognize as fairness. The wicked should be punished –quickly –to the extent that pain will deter them from committing a crime again. Deterrence theory so permeates our thinking that we recognize it as the model by which…
Electric Current (the movement of electrons) in a wire can produce a force at a distance (a field) on metals made of any combination of Iron, Nickel, and Cobalt. This is an electromagnet. All neutral atoms have electrons moving in orbits. Some atoms (Iron, Nickel, and Cobalt) have an electron arrangement that act like tiny…
DNA or nucleic acid is a polymer of nucleotides. A nucleotide consists of 3 molecules: a 5-carbon sugar (pentose) either deoxyribose (in DNA) or ribose (in RNA) a phosphate attached at the #5 carbon of the sugar an organic or nitrogenous base – a nitrogen containing ring structure – attached at the #1 carbon of…
In chemistry, isomers are compounds with the same molecular formula but different structural formulas. The word is derived from the Greek ισομερης, isomerès; isos = “equal”, méros = “part”. There are many different classes of isomers, like stereoisomers, enantiomers, geometrical isomers (see chart below). Isomers do not necessarily share similar properties, unless they also have…
Water is a unique substance essential to life. It is the most abundant molecule in any cell. Human body is 55-78% composed of water. 1. Polar Molecule – A polar covalent bond is formed between the oxygen and hydrogen. The oxygen atom is slightly negative and the hydrogen is slightly positive due to unequal sharing…
VIII Then, the elderly man said, “I have a story that will make you believe in God.” 6 The reason death sticks so closely to life isn’t biological necessity – it’s envy. Life is so beautiful that death has fallen in love with it, a jealous, possessive love that grabs at what it can. But…
The term “modernism” designates a movement in art, literature and music, beginning in the 19thC and lasting into the 20thC, ending approximately with WW II. Art which is modernist may possess the following 12 characteristics: it is psychological in nature and attempts to render individual consciousness or a more subjective reality its depiction of time…
The character of Beloved is a paradigm for an angry, painful sense of memory and suffering. She starts out as a vengeful, willful ghost who haunts Sethe, the woman who gave birth to and also killed her in the past. As soon as Sethe encounters Beloved, while she doesn’t seem to understand or react emotionally…
Existentialists believe that man’s own individual experience or “existing” comes before anything such as a general purpose, goodness or “truth,” or any other Absolute that may be felt to exist. Man creates himself through his own thoughts and actions since the only reality for an individual is that of his own personal existence and nothing…
