Q

what are systematics

A

current classification system using all info known about the organism

31
Q

what is the info that we use to classify organisms

A

cell type, structures, habitat, DNA, evidence, common ancestry, food and energy

32
Q

what is Taxonomy

A

the branch of science concerned with the classification of organisms

33
Q

what are the 3 domains that divide all organisms

A

bateria, Archea, Eukarya

34
Q

what is the bacteria domain

A

simple cell organisms

35
Q

what is the Archea domain

A

single celled organisms with special structures that live in extreme conditions

36
Q

what is the Eukarya domain

A

single or multi celled organisms that have a nucleus

37
Q

what are kingdoms

A

smaller divisons of domains

38
Q

which domains only have 1 kingdom

A

bacteria and archaea

39
Q

how many kingdoms does Eukarya have

A

4 kingdoms

40
Q

what are the 4 Eukarys kingdoms

A

Fungi, Plante, Protis, scientific names

41
Q

what is a nucleus

A

the structure in a cell that contains the chromosomes

42
Q

what is the Fungi kingdom about

A

single or multi celled organisms that absorbs food

43
Q

what is the Plante kingdom about

multi celled organisms that take in food

44
Q

what is the Protis kingdom about

A

single celled organisms that are more complex than those organisms of the Bacteria and Archea domains

45
Q

who originated the naming system for organisms

A

Carol Linnaeus, a sweetish physician in the 1700s

46
Q

what is biomedical nomenclature

a 2 word scientific name for every organism consisting of its genus and species

47

a group of organisms that can produce fertile offspring

48
Q

what is a genus

A

groups of similar species

49
Q

why is using scientific names usful

A

it permits anyone in the world to use the same name for all organisms, makes communication easier

Q

what are cladograms

A

branched diagram that shows the relationship among organisms, including common ancestry

53
Q

what does a cladogram look like

A

a brached diagram with each brach leading to a new characteristic and all organisms to the right of the branch that show that characteristic

54
Q

what does using a microscope enable

A

people to see details of living things that they could’t see otherwise

55
Q

who made the first simple microscope and what did he discover

A

Robert Hook 1600s english scientist discovered cells

56
Q

who made improvements to the microscope after Robert Hook

A

Anton van Leeuwenhoek, Dutch merchant

57
Q

what do all microscopes do

A

magnify objects and have a resulution

58
Q

what does magnification mean

A

makes an object appear larger than it really is

59
Q

what does resolution mean

A

how clearly the magnified objects can be seen

60
Q

how do light microscopes work

A

use a light source and lenses to enlarge the image of an object

61
Q

how does a simple light microscope work

A

has one lens to create an enlarge image

62
Q

how does a compound light microscope work

A

has 2 or more lenses to crate the image, each lense make the image larger, has a greater magnification than the simple microscope

63
Q

how do you determine how many times an object is magnified over its actual size

A

multiply the power if the ocular lens by the power of the objective lens

64
Q

what is the maximum magnification

A

is 1500x the actual size

65
Q

how does an electron microscope work

A

uses a magnetic field to pass through a beam of electrons to or through the object

66
Q

does a light microscope or a electron microscope have a greater magnification ability

A

the electron microscope has a greater magnification ability than the light microscope - up to 100,000x. The electron microscope has a greater resulution

67
Q

why can’t a transmission electron microscope (TEM) test on alive objects

A

because the objects are mounted in plastic and sliced thin

68
Q

how does a transmission electron microscope work (TEM)

A

an electron beam is passed through the specimen

69
Q

How does a Scanning electron microscope (SEM) work

A

elecrtrons are bounced off the surface to create a 3d image ob the object

70
Q

how does health care use microscopes

A

to diagnose problems and in surgery to give the doctor a greater detail of the area

71
Q

how do forensic scientists use microscopes

A

they study evidence from crime scenes

72
Q

how do anthropologists use microscopes

A

they study fossils

73
Q

how do commercial industries and the jewelry industry use microscopes

A

can look at impurities of a product or quality of a stone
