Cards (49)

  • An evidence in a text that readers can use to illustrate their ideas and support their claims
  • using exact words from the original text
  • writing a particular text using your own words
  • condensing a text without omit
    ting essential details
  • a concise summary of a research paper or entire thesis
  • Project proposal presents a solution to a specific problem
  • Research report is a compressed representation of a research
  • Literature review is focused on subjects or topic related to particular questions as proven from previous researches
  • Resume serves as a compilation of the important information needed for a person to land a job
  • Mail or E-mail formal way of communicating your thoughts, ideas and inquires addressed to different people
  • Tremors are the shaking of the ground during an earthquake
  • Rupture occurs when the tremors leave a sizeable fissure or crack to the surface
  • Liquefication is the softening of the soil due to seismic shaking that mixes the loose sediments to the ground
  • tsunami means harbor wave, a series of waves that travels outward from the point of origin
  • landslide may occur or after an earthquake , a portion of steep land weakens
  • the five earthquake hazards are landslide, tremors, rupture, tsunami and liquefication
  • ash fall can cause minor to major damage to vehicles and buildings, contaminate water supplies, and cause respiratory problems
  • 99% of the gas molecule emitted during a volcanic eruption eruption are water vapor, carbon dioxide and sulfur dioxide is volcanic gases
  • lahar may be a crater lake , a dam collapse or heavy rainfall washing ash from the slope of a volcano
  • ballistic comprise fragments of magma and old rocks ejected during an eruption
  • lava flows are streams of molten rocks
  • debris avalanche is a volcanic hazard
  • phases of the cell cycle consist of interphase and the miotic phase
  • interphase is the normal cell activity
  • miotic phase is cell division
  • diploid cell possessing two copies of each chromosome( human body cell)
  • haploid a cell possessing a single copy of each chromosome (human sex cells)
  • in prophase the chromatin become more tightly coiled, condensing into discrete chromosome with a light microscope. each duplicated chromosome appears as two identical sister chromatids joined together
  • in metaphase chromosomes line up along the middle of the cell
  • anaphase is the shortest stage of mitosis. it begins when the two sister chromatids of each pair suddenly part .
  • in Telophase two daughter nuclei begin to form in the cell. the chromosomes become less condensed
  • cytokinesis -cleavage of cell into halves
  • Meiosis reduces the chromosome number such that each daughter cell.
  • the period of time between meiosis 1 and meiosis 2 is called Interkinesis
  • no replication of DNA occurs during interkinesis because the DNA is already duplicated
  • building blocks of life called macromolecules
  • carbohydrates - organisms main source of enegry
  • complex sugars are called starches
  • tough fiber found in the plants is made up of the carb "cellulose
  • Lipids is made of glycerol and fatty acids
