Answer 7

type of logic where specific results are predicted from a general assertion

Question 8

Answer 8

descriptions rather than than measurements

Question 9

Quantitate data

Answer 9

numbers and measurements based

Question 10

Controlled experiment

Answer 10

manipulate the variable that is predicted to cause difference’s between groups

Question 11

Comparative experiment

Answer 11

look for different between the samples or groups
ex. body size of different sexes

Question 12

Independent variable

Answer 12

the variable being manipulated

Question 13

Dependent variable

Answer 13

the variable that changes as a result of the independent variable
ex. mass of both groups

Question 14

Atom

Answer 14

smallest unit that retains properties of element

Question 14

Element

Answer 14

a substance that cant be changed or broken down anymore

Question 15

subatomic particles

Answer 15

proton (+), neutron, electron (-)
protons and neutrons give an atom mass

Question 16

isotopes

Answer 16

different forms of the same element
–> number of neutrons is changed

Question 17

Atomic mass

Answer 17

neutrons + protons (top left corner)

Question 18

Atomic number

Answer 18

protons (bottom left corner) not always given

collection of many, many genes

Question 20

genes

Answer 20

information needed to produce proteins is contained here

Evolution

Answer 23

change over time

Question 24

Descent with modification

Answer 24

descendants are different from ancestors because they change over time

Question 25

3 Important patterns noted by Darwin
