Front 1

Ingestion

Back 1

taking in food; eating

Front 2

RNA

Back 2

nucleic acid that "reads" the genetic information carried by DNA and guides the protein making process

Front 3

Fats

Back 3

substance that supplies the body with energy and also helps support and cushion the vital organs in the body:
solid at room temperature

Front 4

Sugar

Back 4

one of the main types of carbohydrates

Front 5

Digestion

Back 5

a process where large carbohydrates are broken down into smaller carbohydrates

Front 6

Respiration

Back 6

process in which simple food substances such as glucose are broken down and the energy they contain is released

Front 7

Stimulus

Back 7

signal to which an organism reacts; changes in the environment

Front 8

Homeostasis

Back 8

ability of an organism to keep conditions inside its body the same, even though conditions in its external environment change

Front 9

Development

Back 9

the growth of a human body

Front 10

Sexual Reproduction

Back 10

reproduction usually involving two parents in which a sex cell from each parent unite to form an offspring

Front 11

Movement

Back 11

the process of moving

Front 12

Carbohydrates

Back 12

energy rich substance found in foods such as vegetables, cereal grains, and breads ;sugars and starches.
they are composed of carbon, hydrogen and oxygen.
they serve as the main source of energy.

Front 13

Proteins

Back 13

substance used to build and repair cells; made up of amino acids.
are composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur and phosphorus.

Front 14

Lipids

Back 14

-include fats, waxes and oils
-composed of carbon, hydrogen, and oxygen
-secondary source of energy

Front 15

Nucleic Acids

Back 15

large, organic compound that stores information that helps the body make the proteins it needs; DNA or RNA.

Front 16

Spontaneous Generation

Back 16

hypothesis that states that life can spring from non-living matter.

Front 17

Francesco Redi

Back 17

an Italian physician who was the first to attempt to disprove spontaneous generation.

Front 18

Inorganic Compounds

Back 18

compound found in living things that does not contain the element carbon

Front 19

Organic Compounds

Back 19

compound found in living things that contains the element carbon.

Front 20

DNA

Back 20

nucleic acid that stores the information needed to build proteins and carries genetic information about an organism.

Front 21

Catalyst

Back 21

speed up or slow down a chemical reactions but are not used up by the reaction.

Front 22

Amino Acids

Back 22

building blocks of protein.

Front 23

Genes

Back 23

DNA is the molecule of which your genes are made.

Front 24

Starch

Back 24

also known as polysaccharides.
starches are also complex carbohydrates.

Front 25

Metabolism

Back 25

the sum total of all chemical activities in an organism.

Front 26

Excretion

Back 26

the process of getting rid of waste materials.

Front 27

Response

Back 27

some action or movement of an organism brought on by a stimulus.

Front 28

Back 28

maximum length of time an organism can be expected to live.

Front 29

Asexual Reproduction

Back 29

reproduction requiring only one parent.

Front 30

Competition

Back 30

the struggle among organisms, both of the same or different species to fight for food, water, and energy from the sun.

Front 31

Energy

Back 31

All living things need energy. The primary source of energy is the sun. That is where the organisms in plants or animals get there energy to run, or produce more flowers.

Front 32

Lazzaro Spallanzani

Back 32

was an Italian naturalist, who also attemted to disprove the theory after about one hundred years after Redi.
-Theory solved by using the broth

Louis Pasteur

Back 33

he finally disproved the theory using the "S" shaped tubes connected to the broth.

Front 34

Biogenesis

Back 34

the production of living organisms from other living organisms
