Arrange the following measurements from the smallest to largest meter millimeter centimeter micrometer.
Micrometer millimeter centimeter meter
When measuring liquids in a graduated cylinder you must make sure the lowest margin of the water level or blank is at the correct Mark for the volume you are measuring
Miniscus
A lengthwise cut through any type of specimen is called a
Longitudinal
Water freezes at blank Celsius and boils at blank Celsius
Zero; hundred
The standard system of measurement in the sciences including biology chemistry and physics that has tremendous advantages because all conversions weather for volume mass or length are in units of 10 is blank
Cross-section
The blank is designed to study entire objects in three dimensions at low magnification
Stereo microscope or dissecting microscope
The blank also known as the stereomicroscope allows you to view objects in three dimensions at low-power
dissecting microscope
The blank holds the nose piece at one end and the eyepiece on the other end and conduct light rays
Body tube
The stereo microscope has a light to illuminate the object your viewing called the blank
Illuminator
When viewing an object on a compound microscope you place your slide on the blank which holds and supports the microscope slides
Stage
The blank uses two sets of lenses to view an object it is used to examine smaller objects or those sliced into sections
Compound light microscope.
A lead system below the stage used to focus the beam of light on the object is called the blank.
Condenser
The lowest power objective on the microscope use to scan the whole slide is the blank.
Scanning power objective
The adjustment knob used to bring the object into approximate focus used only with the scanning and low-power objective is the blank.
Course adjustment knob
100 X objective used to achieve the greatest magnification is called the blank.
Oil immersion objective
When a specimen is prepared for observation on the compound light microscope the object should be viewed as a blank.
