Flashcards in Lab Test 1 Deck (52):
1

Three subsequences of domain

Bacteria, archea, eukarya

2

Subsequences of kingdom

Protista, fungi, plantae, animaila

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
