A

grouping of species w certain traits in common

22
Q

Groupings

A

Domain, kingdom, phylum, class, order, family, genus, species

23
Q

three domains

28
Q

spot where life branches off in tree

A

most recent common ancestor

29
Q

Which of the two (prokaryotes or eukaryotes) have a nucleus

A

eukaryotes

30
Q

where is prokaryotic dna contained

A

freefloating instead of nuclear membrane

31
Q

Which of the two (prokaryotes or eukaryotes) has a smaller cell?

A

Prokaryotic have smaller and simpler cells, while eukaryotic larger and many live as multicellular

38
Q

first step scientific method

A

identify problem

39
Q

second step scientific method

A

develop hypothesis and make prediction (if/then statement)

40
Q

hypothesis

A

testable explanation of process

41
Q

prediction

A

statement of what you should find in nature

42
Q

third step scientific method

A

experiment

43
Q

experiment

A

test carried out under controlled conditions and manipulated by researchers

44
Q

fourth step scientific method

A

repeat the tests/devise new ones if hypothesis went through. if not, go back to step 2.

45
Q

fifth step scientific method

A

analyze/report test results and conclusion

46
Q

scientific theory

A

hypothesis not disproved over course of years–researchers can’t find evidence disproving it, low probability of being wrong
