Essentials Of Biology Chapter 1

Front 1

Whatis Biology?

Back 1

Scientific study of life.

Front 2

What are the characteristics of living

organisms?

Back 2

-Life is Organized

-Need energy

-Respond to Stimuli

-Reproduce

-Evolution & Adaptation

-Homeostasis and regulation

Front 3

What is the core principle of Biology and why?

Back 3

Evolution because it explains the unity and

diversity if life.

Front 4

Can you list the levels of organization from the smallest to the largest?

Back 4

Atom

Molecule

Cell

Tissue

Organ

Organ System

Organism

Population

Community

Ecosystem

Biosphere

Front 5

Explain what happens to chemicals(materials) and what happens to energy in an ecosystem.

Back 5

Energy is the ability to do work

energy is burned

when cells use nutrient molecules to make their parts and products, they carry out a sequence of chemical reactions

Front 6

What is the mechanism of evolution?

Back 6

it occurs by natural selection.

if your environment is good you will survive and reproduce.

e.g frog; drought happens, it turns brown

Front 7

Explain the process of natural selection.

Back 7

if you can adapt and survive, you reproduce.

e.g. birds

Front 8

Identify the components of the “Scientific Method”

Back 8

observation

hypothesis

experiment

conclusion

Front 9

•What are the steps of the scientific method?

Back 9

1. observation

2. hypothesis

3. experiment/test

4. data

5. conclusion

Front 10

•What is necessary for a hypothesis to be valid?

Back 10

observation and that it can be tested

Front 11

•What is necessary for a good experiment that is valid?

Back 11

a good experimental design

Front 12

•What is science?

Back 12

A Way of Knowing

Front 13

•What is technology?

Back 13

the application of science knowledge for a particular purpose

Front 14

•What is bioethics?

Back 14

branch of ethics concerned with the development and consequences of technology

Front 15

•What is biodiversity?

Back 15

variation of life on earth

number of different species

Front 16

•What is extinction?

Back 16

death of a species

Front 17

•What is a primary source of information? A secondary source?

Back 17

Primary: provides direct or firsthand evidence about an event, object, person, or work of art.

(e.g historical and legal documents, eyewitness accounts, results of experiments)

Secondary: created later by someone who did not experience first-hand. (e.g. TV, Magazine)

Front 18

•What is a peer reviewed study?

Back 18

closely examined by a panel of reviewers who are experts on the topic

Front 19

•How is a “theory” in science different from a “theory” in everyday language?

Back 19

theory in science: is supported by a lot ofevidence.

theory in language: speculation

Front 20

What is a cell?

Back 20

-the smallest most basic unit of life.

-although alive it is made up of nonliving

molecules

Front 21

metabolism

Back 21

the chemical reaction that occurs in a cell during growth and repair

Front 22

homeostasis

Back 22

self regulating mechanism; hypothalamus

Front 23

evolution

Back 23

the process by which different kinds of living

organisms are thought to have developed

Front 24

taxonomy

Back 24

identifying, describing, and naming organisms

Front 25

What are the three domains of life?

Back 25

1. Archaea

2. Bacteria

3. Eukarya

Front 26

What are the 4 kingdoms under Eukaryotes?

Back 26

1. Protista

2. Fungi

3. Plantae

4. Animalia
