the work horses of the cell

60
Q

the reproduction process is

A

a copy of the parents DNA being passed on to the offspring

61
Q

why do offspring resemble their parents?

A

they share the same genetic material (DNA)

62
Q

what does photosynthesis produce?

A

sugar and o2

63
Q

what are heterotrophs?

A

organisms who need to eat other organisms as food (animals)

64
Q

what are autotrophs?

A

organisms who make their own food (plants)

65
Q

what is respiration?

A

cells break down organic molecules(sugar) to make high energy compounds. These compounds are used for growth and metabolism

66
Q

where do cells come from?

A

pre-existing cells, by cell division

67
Q

what type of organization do organisms have?

A

internal

68
Q

why do organisms have an internal organization?

A

so that the living cell is separated from the external environment

69
Q

biology

A

the study of life

70
Q

what are the classifications of living things?

A

domain bacteria, domain archae, and domain eukarya

71
Q

what is in domain eukarya?

A

the eukaryotes

72
Q

why has the kingdom monera changed into the domain of bacteria and archae?

A

better techniques have allowed us to differentiate more between them and their cellular structures

73

Q

what are two types of domain bacteria?

86
Q

what is taxonomy and how does it work?

A

different organisms being grouped together based on their similarities and relatedness. species with a recent common ancestor are grouped together and ones who share a distant ancestor are placed in different groups

87
Q

in taxonomy, related species are grouped into the same

A

genus

88
Q

in taxonomy, after the genus, they are grouped into

A

family

89
Q

A

the genus is capital and the family is either underlined or italicized

90
Q

what is binomial nomenclature?

A

each species is given a two part scientific name in Latin.

91
Q

describe the two part of the binomial nomenclature

genus: shared by other closely related organisms
species: unique to that specific organism

the appearance

93
Q

what is a hypothesis and what is it based on?
what should the predictions be like?

A

a proposed explanation for a natural phenomenon. It is based on observation or scientific knowledge.
They should be testable

94
Q

what is science?

A

observation, identification, experimental investigation, explanation of natural phenomena

95
Q

if the prediction of the hypothesis is incorrect…

if the prediction of the hypothesis is correct…

A

the hypothesis has been proven false
the hypothesis is consistent with known data

96
Q

what is a theory?

A

a broad explanation of some aspect of the natural world that is supported by a large body of evidence

97
Q

what do theories incorporate?

A

observations, hypothesis testing, and other disciplines of science such as physics and chemistry

98
Q

what does a theory establish and explain?

A

they establish a set of ideas and explain a vast amount of data that offers valid predictions that can be tested

99
Q

discovery based science is…

A

collection and analysis of data without a preconceived hypothesis. these observations may lead to the formation of new hypotheses or discoveries

100
Q

hypothesis based science and the scientific method is…

A

when observations are made about a certain biological process. a hypothesis is made that explains the observations. a good hypothesis will make testable predictions and experiments are performed to test them. the data is analyzed and the hypothesis is considered consistent with the data or false

101
Q

experimental design is…

A

a controlled experiment where it contains two groups (the control and experimental), that vary in only one factor that is being tested. there are multiple organisms in each group and the data is analyzed to determine if the two groups are SIGNIFICANTLY different from each other.

102
Q

what is Koch’s postulates?

A

the suspected pathogen must be present in every case of the disease. then the pathogen must be isolated from the host and grown in a lab dish. the disease must reproduced when a pure culture of the pathogen is inoculated into a healthy host. the same pathogen must be recovered again from the experimentally infected host.

103
Q

what is a double blind study?

A

neither the doctors nor the patients know which medication they are given to not screw the results
