1

What is biology?

The study of life

2

What is the process of science?

A way of knowing; based on inquiry
Is limited to natural phenomena; use natural causes to explain natural phenomena
It is falsifiable and self-correcting
Two main approaches: discovery/descriptive science and hypothesis-driven science.
A hypothesis is a tentative answer to a question

3

___ Science describes nature.

Discovery/descriptive science

4

Discovery/descriptive science uses....

Observation, measurements; descriptions, data, and observations confirmed by others

5

What is inductive reasoning?

Many specific observations which lead to a general description or hypothesis (Specific to General)

6

__ Science explains nature.

Hypothesis-driven science

7

What is deductive reasoning?

A general statement which an individual can make a specific. (General to Specific).

8

What is a theory?

A comprehensive explanation supported by evidence.

9

What are the properties of life?

Order
Regulation
Reproduction
Growth and development
Energy utilization
Response to the environment
Evolution

10

What are prokaryotic cells?

No membrane around their DNA

11

What are Eukaryotic cells?

Have a membrane around the DNA; membrane bound nucleus

12

The two classifications to consider when grouping similar organisms are?

Cell structure and Nutrition.

13

What are the three domains of life?

Bacteria, Archaea, and Eukarya

14

What is energy?

How an organism gets energy

15

What is a decomposer?

Decomposers cause things to break down/rot.

16

What is a photosynthetic organism?

An organism which uses photosynthesis for nutrition.

17

Describe ingesting food organisms...

An organism that takes in nutrition through the mouth or gullet.

18

Eukaryotic organisms are divided into...

Kingdoms (Protista, Fungi, Plantae, and Animalia)

19

Is Bacteria Prokaryotic or Eukaryotic?

Prokaryotic

20

Is Eukarya Prokaryotic or Eukaryotic?

Eukaryotic

21

Is archea prokaryotic or eukaryotic?

prokaryotic

22

What are the kingdoms of the Eukaryotes?

Protista, fungi, plantae, and animalia,

23

How does a protista obtain its nutrition?

Varies because some are photosynthetic, some ingest food, as some are decomposers.

24

Classify a Fungi

Cell type: Eukarya
Nutrition: Decomposers
Examples of a fungi: Molds, mildew, mushrooms, and yeast.

25

Classify a Protista

Cell type: Eukarya
Nutrition: Some photosynthetic, some ingest food; some decompose.
Examples: Amoeba, algae, seaweeds

26

Classify an Animalia

Cell type: Eukarya
Nutrition: Ingest food
Examples: humans, earthworms, insects, lobster, sea stars, clams, tapeworms.

27

Organisms in each kingdom are further classified as...

Kingdom
Phylum
Class
Order
Family
Genus
Species

28

What is binomial nomenclature?

When an organism is identified by its genus and species name.

29

Viruses are not

Cells

30

Characteristics of a virus?

They have DNA or RNA but not both
They can only reproduce within a host cell.
They do not have organelles
They do not have metabolic properties.
