3
Order of Taxons
Domain, kingdom, phylum, class, order, family, genus, species
4
How to write the binomial nomenclature?
Genus name is first (capitalized) followed by species name (lowercase) with both either italicized or underlined
5
Experimental, factor that you were changing
Independent variable
6
The thing you are measuring, a result of the independent variable
Dependent variable
7
everything else that is kept constant
Standardized variable
8
Group that doesn't get the experimental variable
Control group
9
The larger the __ The better the experiment results
Sample size
10
Steps of the scientific method
Observation, hypothesis, productions and perform experiments, Data collection, conclusion
11
Educated guess
Hypothesis
12
Hypothesis that Has lots of evidence
Theory
13
Has so much evidence that is considered true
Law
14
Can't prove a hypothesis, but can __
Support and disapprove
15
Everything seen in the circle
Field of view
16
Increases the size of a specimen
Magnification power
17
How detailed image is
Resolving power
18
Characteristic of a lens, distance from the lens in specimen where the specimen is in sharp focus
Plane of focus
19
Thickness of a specimen that is in chart focus, the higher the power lens the less of this
Depth of field
20
Field of view and magnification have a __ ; as field of view decreases the magnification increases
Inverse relationship
21
Dense region of the nucleus that is involved in the production of rRNA
Nucleolus
22
Membrane-bound organelle that has DNA
Nucleus
23
Regulates what goes in and out of the cell
Plasma membrane
24
Structure of plasma membrane
Phospholipids, sterols (cholesterol), proteins, fluid Mosaic model(cholesterol helps with fluidity)
25
Plasma membrane's fluid Mosaic model
Made of a lot of different proteins, fluidity is due to cholesterol and means that it is not rigid
26
Membrane-bound storage vessel
Vacuole
27
Semi fluid that contains organelles
Cytoplasm
28
Function is to maintain cell shape
Cell wall
29
Proteins embedded and semi permeable, regulates what goes in and out
Plasma membrane
30
How to prepare a wet mount
Take the slide, put a specimen on the slide, put a drop of water on it, put a coverslip on top
31
Substrate of the organelle lab (potato slushy)
Hydrogen peroxide
32
Enzymes of the organelle lab
Catalase and catacholase
33
Catalase reaction
Speeds up the breaking down of hydrogen peroxide to water and oxygen
H2O2 -> H2O + O2
34
When catacholase is in the presence of oxygen, ___ is produced
Melanin
35
__ makes the color change quicker because it produces __ which is what catacholase acts on to produce __
Catalase
Oxygen
Melanin
36
Movement of molecules from an area of high concentration to an area of low concentration
Diffusion
37
Diffusion of water through a semi permeable member
Osmosis
38
Substrate of enzyme lab
Hydrogen peroxide
39
Enzyme of the enzyme lab
Catalase
40
Lens through which you view magnified specimen.
Ocular lens
41
Movable Mount for selecting the objective lens which provides the magnification desired
Revolving nosepiece
42
Lens on revolving nose piece, which accomplishes the initial magnification of the species
Objective lens
43
Flat work surface upon which the slide is placed
Stage
44
Regulates the amount of light passing through the stage aperture and specimen
Iris Diaphragm
45
Constant light source beneath the iris diaphragm
Lamp
46
Has a lever that is open that early to except insecure the slides to the stage
Mechanical stage
47
Gives initial focus on low-power
Course adjustment knob
48
Gives refined focus on low powers, high power, oil immersion
Fine adjustment knob

A compound microscope has
Two sets of lenses
51
A monocular has
One Eyepiece
