Biology 143 Delgado Test 1-Answered
Accuracy - ANSWER-A description of how close a measurement is to the true value of
the quantity measured.
Base unit - ANSWER-a defined unit in a system of measurement that is based on an
object or event in the physical world
Benedict's reagent - ANSWER-an alkaline solution of copper(II)sulfate used in the
chemical tests for reducing sugars and non-reducing sugars. A brick-red precipitate
indicates a positive result.
binocular - ANSWER-pertaining to two or both eyes
Biuret test - ANSWER-A biochemical test for the presence of proteins.
body tube - ANSWER-Connects the eyepiece to the revolving nosepiece
Carbohydrates - ANSWER-the starches and sugars present in foods
Celsius - ANSWER-Metric unit for measuring temperature; On this scale water freezes
at zero and boils at 100.
condenser lens - ANSWER-located immediately below the specimen, focuses light from
the light source onto the specimen
Contrast Microscopy - ANSWER-shows presence of dye or other treatments
Control - ANSWER-In an experiment, the standard that is used for comparison
Conversions - ANSWER-the act or an instance of converting or the process of being
converted.
course adjustment knob - ANSWER-Moves the stage up and down for focusing; Cannot
be used during high power or the objective lens can crack
dehydration synthesis - ANSWER-A chemical reaction in which two molecules
covalently bond to each other with the removal of a water molecule.
density - ANSWER-mass/volume
Depth of Field (DOF) - ANSWER-The amount of your image that will be in
focus.
Disaccharides are - ANSWER-double sugars
