Q

Plants

A

Use the suns energy to create chemical energy

19
Q

Animals

A

Feed on producers and other consumers to acquire energy

20
Q

Ecosystems

A

Organisms within an ecosystem interact with sunlight

21
Q

Feedback

A

The output or product of a process regulates that very process/ is a method of regulation

22
Q

Positive feedback

A

The product of a process promotes the process to continue

23
Q

Negative feedback

A

The product of the process stops or deceases the process

24
Q

Evolution

A

Species are descendants of ancestral species that were different from the present day species

25
Q

Evolutionary mechanisms

A

Account for the unity and diversity of all species on Earth

26
Q

Classifications of life

A

Largest to smallest: Domains, Kingdom, phylum, class, order, family, genus, species

27
Q

Taxonomy

A

Is the branch of biology that’s name and classifies species into groups of increasing bread

28
Q

Bacteria

A

Prokaryotes

29
Q

Archaea

A

Prokaryotes

30
Q

Eukaryotic

A

Eukaryotes

31
Q

Unity

A

There are features that are shared or are common among different species

32
Q

Diversity

A

There are features that are different among different species

33
Q

Darwin’s law in Evolution

A

Means of natural selection 1859
Darwin’s theory explains the duality of unity and diversity

34
Q

Darwin two main points

A

Species descent with modification from common ancestors

Natural selection is behind descent with modification

35
Q

Natural selection

A

The concept of evolutionary adaptation

36
Q

Natural selection to work

A

There must be genetic variation within the population heritable traits

Different traits of individuals as a result different phenotypes

Reproduction must occur
Individuals don’t evolve a species does

37
Q

The family tree

A

Based on unity and diversity

38
Q

Scientific method

A

Looking for cause and effect relationships in nature

Seeking to discover how things work

Making sure we have evidence to support our conclusion

Science is about observation and data

39
Q

Hypothesis

A

A testable explanation or answer to a question or for an observation based on available data

40
Q

Doesn’t work with scientific methods

A

Ghost, religion and supernatural

41
Q

Experiment

A

Involve manipulating one factor in a system in order to collect data in regards to how this factor affects the system

42
Q

Independent variables

A

The factor you manipulate

43
Q

Dependent variable

A

Is the outcome of the data you collected what you measured

44
Q

Control

A

Is a group which scientist did not manipulate a variable so they can compare their experiment to this untouched group
