Biology

Front 1

science

Back 1

organized way of gathering and analyzing evidence about the natural world

Front 2

observation

Back 2

the act of noticing and describing events or processes in a careful orderly way

Front 3

inference

Back 3

logical interpretation based on what sciences already knew

Front 4

hypothesis

Back 4

is a scienctific explanation for a set of observations that can be tested in ways that support or reject it

Front 5

controled experiments

Back 5

when a hypothesis is tested by an experiment in which only one variable changes, while all other variables should be kept unchanged

Front 6

independent variable

Back 6

variable that is deliberately changed

Front 7

dependent variable

Back 7

variable that is observed and that changes in response to the independent variable

Front 8

control group

Back 8

is exposed to the same conditions as the experimental group except for one independent variable

Front 9

data

Back 9

detailed records of experimental observation, gathering info

Front 10

biology

Back 10

study of life

Front 11

dna

Back 11

where all organisms store complex information they need to live, grow, and reproduce in a genetic code written in a molecule

Front 12

stimulus

Back 12

signal to which an organism responds

Front 13

sexual reproduction

Back 13

vells from two parents unite to form the first cell of a new organism

Front 14

asexual reproduction

Back 14

a single organism produces offspring identical to itself

Front 15

homestasis

Back 15

condition where internal enviroment relatively stable even when external conditions change dramatically

Front 16

metabolism

Back 16

combo of chemical reactions through which an organism builds up or breaks down materials

Front 17

biosphere

Back 17

living planet

Front 18

what procedures are at the core of scientific methodology?

Back 18

observing, asking questions, making inferences, form hypotheses, conduct controled experiments, collect and analyze data, draw conclusions

Front 19

what makes a good scientist

Back 19

curiosity, skepticism, open-mindness, creativity

Front 20

what does it mean to be skeptical

Back 20

to not accept any information without seeing evidence

Front 21

what are some characteristics that all living things share

Back 21

basic unit of cells, on a universal genetic code, obtain and use materials and energy, grow/develop, reproduce, respond to their enviroment, maintain a stable internal enviroment, change over time
