Que font les sociologues? 1. Identifient les tendances - Observent les regularités sociales (situations qui se répètent; nous appartenons tous dans des catégories sociales) 2. Étudient & mettent en question les présupposés - Quelle impacte les films, etc. qui supportent les présupposés. 3. Comment les stéréotypes diffèrents parmis différentes catégories sociales. Qu'est-ce que sa donne la sociologie? 1. Mieux comprendre le monde qui nous est alentours. 2. Meilleure c...

3 conditions define social problems -Objective, condition negatively affects large # of ppl -Subjective, Govt/influential group recognizes problem -Condition can be solved by collective action Poverty definition over time Once seen as individual problem, but now seen as public issue, post great depression Racism definition over time Civil rights post WW2 difference Domestic violence definition over time post vs before womens movement Who are Baby boomers Born b...

Explain why plasma membranes are said to have a fluid mosaic structure. 1. Fluid because the phospholipids are constantly moving. 2. Mosaic because the proteins are scattered throughout the membrane-like tiles in a mosaic. What effect does cholesterol have on the cell membrane? 1.Cholesterol molecules fit between the phospholipids and bind to the hydrophobic tails of the phospholipids. 2.Causes them to pack together more closely, restricting the movement of other molecules in the membra...

Describe the events of fertilisation that occur after the acrosome reaction. -Membrane of sperm and egg cell fuse together -cortical granules release contents into zona pellucida -Zona pellucida thickens -Haploid nuclei fuse Explain how phospholipids form a cell surface membrane -Hydrophilic parts associate with water -Hydrophobic parts repel water -a bilayer forms with hydrophobic parts pointing in towards the centre of the bilayer Describe the role of the CFTR protein in e...

Molecular phylogeny It compares the structure of a particular molecule from different organisms to discover their degree of evolutionary relation. Somatic cell A cell in an organism which isn't a gamete. DNA Deoxyribose nucleic acid. Carries the genetic information for cells and some viruses. mRNA Messenger ribose nucleic acid (single stranded). The product of transcription. Speciation The process through which a species is created Sympatric Due to repro...

what is simple diffusion molecules pass directly through the plasma membrane without the assistance of another molecule, from a higher concentration to a lower concentration. when is simple diffusion used to allow molecules to travel in and out of the cell membrane: examples water, o2, co2 and ethanol. What is a phospholipid? It is a lipid that has a phosphate group attached to the glycerol and only two fatty acid chains. What is a protein? chain of amino acids ...

Packaging considers Protecting surfaces from physical damage and corrosion Site Surveys should be done at the user site: early in the program so that any site modificatoin orneeded new construction is completed prior to End Product transition Forms of End Product transition include: Select the two correct answers. Delivery of lower level products to higher-level ones for integration Ultimately, delivery of an end product to its customer or user. An outcome of the Transit...

Fumaric acid has two conjugate base forms, with pKa1=3.02 and pKa2=4.48, at what pH value αHA- got its largest fractions? a. 3.02 b. 4.48 c. 3.75 d. 5.41 c. 3.75 For a diprotic system, the equation for the fraction of A2-(αA2-) is a. αA2- = K1K2/([H+]2+[H+]K1+K1K2) b. αA2- = [H+]2/([H+]2+[H+]K1+K1K2) c. αA2- = K1K2/([H+]+[H+]K1+K1K2) d. αA2- = [H+]2/([H+]+[H+]K1+K1K2) a. αA2- = K1K2/([H+]2+[H+]K1+K1K2) A 25.00mL solution of 0.0316M benzylamine was titratd with 0.02...
