Chapters 1

Question 1

Biology

Answer 1

The study of life

Question 2

Common characteristics of life

Answer 2

Order, regulation, growth & development, energy utilization, response to environment, reproduction and evolution

Question 3

Order

Answer 3

Complex & ordered organization

Question 4

Regulation

Answer 4

Maintain internal homeostasis when environment changes

Question 5

Growth and development

Answer 5

Based on jeans from generation to generation (information carried by DNA)

Question 6

Energy utilization

Answer 6

Takes in energy and transform it for use

Question 7

Response to environment

Answer 7

Shivering (like Venus fly trap, responds to touch, sensory)

Question 8

Reproduction

Answer 8

Pass on genetic info.reproduce their own kind doesn’t change. Hipo reproduce hipo.

Question 9

Evolution

Answer 9

Reproduction allows change. Evolve in population. Change will

Question 10

Biosphere

Answer 10

All life, or places where life exist. (the earth is the largest level)

Question 11

Ecosystem

Answer 11

Everything living or dead in a region. example: savanna all the animals, water, soil, air

Question 12

Community

Answer 12

All of the organisms like grass, animals, insects. Tide pool

Question 13

Population

Answer 13

One species example zebra

Question 14

Organism

Answer 14

One living thing example one zebra

Question 15

Organ system

Answer 15

Heart and blood vessels

Question 16

Organ

Answer 16

Heart

Question 17

TIssue

Answer 17

Groups of similar cells performing a specific function

Question 18

Cells

Answer 18

The basic unit of life

Question 19

Molecular

Answer 19

A cluster of Adams example DNA

Question 20

Adams

Answer 20

The smallest unit of matter (element)

Question 21

Ecosystem organism interacts with its environment two main processes

Answer 21

1. Cycling of nutrients: nutrients taken up by plants return to the soil
2. Flow of energy in sunlight
   Procedures = plants by photosynthesis
   Consumers animals eat plants, decomposers fungi break down organisms back to minerals.

Question 22

DNA

Answer 22

All cells use DNA

Question 23

Genes

Answer 23

Half of our genes came from each our parents

Question 24

Code for protein

Answer 24

Adenine, thymine, cytosine, guanine (ATCG)

Question 25

Persons sex

Answer 25

Is determined by father, XX vs XY

Question 26

Taxonomy

Answer 26

Field of biology that names and classifies species

Question 27

Life divided into 3 groups (domains)

Answer 27

``` Bacteria= prokaryotic cell Archaea= prokaryotic cell Eukarya= eukaryotic cell ```

Question 28

Domain Eukarya | Has 4 domains

Answer 28

Plantae- multicellular organisms Fungi-multicellular Animalia-multicellular Protista- single cellular, example amoebas

Question 29

Transcription(TRNA) occurs

Answer 29

In the nucleus

Question 30

tRNA

Answer 30

Amenities acids

Question 31

Charles Darwin

Answer 31

The origin of species(2 main points) 1. Decent with modification = based on food and environment species living today descended from ancestral species. 2. Natural Selection= mechanism for #1 they do to help them survive.

Question 32

Darwin Charles

Answer 32

Species can cross breed for once the new species is created they can not go back and breed with the original species due to genetics

Question 33

Overproduction and competition

Answer 33

Too many other species compete for food in survival = not all will survive

Question 34

Individual variation

Answer 34

No two species are alike Some have better survival skills, the strong will adapt. Like turtles, lots are produced boat once hatched from the sea to the ocean crocodiles, birds, and other animals are waiting to eat them.

Question 35

14 species of Finches

Answer 35

Their beaks change due to what they need to eat to survive in the different areas. Some even bigger nuts and some eat smaller nuts.

Question 36

unequal reproduction success is natural selection

Answer 36

The product of natural selection is adaptation. Natural selection is the mechanism of evolution. Best traits are passed to the next generation, adaptation occurs = evolution. Like the moth color changing to survive to blend in to the environment because of all the dark side so birds couldn't spot them.

Question 37

Artificial selection

Answer 37

You pick it's not natural. Breeding dogs.

Question 38

Bacteria

Answer 38

Can use antibiotics

Question 39

Virus

Answer 39

Cannot use antibiotics because it's not a bacteria

Question 40

Science

Answer 40

To know. | Based on inquiry due to curiosity to understand.

Question 41

Two approaches to science

Answer 41

1.discovery science-based on verifiable observations and measurements. Conclusions drawn by inductive reasoning. Summarizes many concurrent observations and measurements. 2. Hypothesis-driven science- consists of series of steps. Observation-question Question-hypothesis Hypothesis-prediction Prediction-testing Results- if results don't match the hypothesis then new hypothesis.

Question 42

With science

Answer 42

Take good notes so someone else can follow the procedure step-by-step and get the same results

Question 43

Watson & Crick

Answer 43

Discovered DNA.
