How diverse a population of organisms in a commuty are

Front 5

environment

Back 5

an area where many species, populations and communities live

Front 6

Competition

Back 6

where animals compete for their resources to live

Front 7

Broad Niche

Back 7

is an animal with a big role in its environment

Front 8

Narrow Niche

Back 8

an animal with a smaller role in its environment

Front 9

Specialization

Back 9

is when an animal specializes something about the behavioural or physical to adapt to a specific way

Front 10

Symbiotic

Back 10

Is when organisms rely on another to live

Front 11

Heritable

Back 11

can be inherited (passed down) by your parents

Front 12

Reproductive

Back 12

ways animals reproduce (sexual reproduction)

Front 13

Asexual Reproduction

Back 13

the organism makes an exact copy of itself

Front 14

Bianary Fission

Back 14

is a form of asexual reproduction where the organism splits into 2

Front 15

spores

Back 15

the reporductive cells for fungi

Front 16

zoospores

Back 16

A motile flagellated asexual spore, as of certain algae and fungi

Front 17

Meristem

Back 17

A meristem is the tissue in most plants consisting of undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place.

Front 18

Clone

Back 18

where the organism makes an exact copy of itself

Front 19

Sexual reproduction

Back 19

each parent passes on traits to their offspring as they each carrie 23 gamets

Front 20

Zygospores

Back 20

sexual spores produced by fungi

Front 21

bacterial conjunction

Back 21

Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.

Front 22

zygote

Back 22

is the initial cell formed when two gamete cells are joined by means of sexual reproduction.

Front 23

Pistil

Back 23

female reproduction part of a plant

Front 24

Stamen

Back 24

male part of flower that contains the pollen

Front 25

Ovule

Back 25

where the ovaries (eggs) are held

Front 26

Pollen tube

Back 26

is a tube where the pollen travels through to get to the ovule

Front 27

Embryo

Back 27

Embryos in animals refer to an early stage of development for the animal between the zygote (fertilized egg) stage and birth.

Front 28

Cotyledon

Back 28

A cotyledon (or "seed leaf") is a significant part of the embryo within the seed of a plant.

Front 29

Genetics

Back 29

The make-up of the human being

Front 30

Continious variation

Back 30

always changing to the environment

Front 31

Discrete Variation

Back 31

what traits you were born with

Front 32

Dominant/Recessive

Back 32

are traits that you inherit from your parents (dominant trumpts recessive, giving it the dominant name).

Front 33

Mutation

Back 33

is a change to your DNA, that can be noticable or not

Front 34

Mutagen

Back 34

is something that changes the DNA of someone

Front 35

Deoxyribonucleic Acid (DNA)

Back 35

Is a phosphate backbone where the codes for our traits are found

Front 36

Chromosones

Back 36

found in the nucleus of each cell and carries the genes f(traits) for the human

Front 37

Somatic/sex cells

Back 37

are the sperm and the ovule. each carry 23 gametes (haploid) and when the sperm fertalizes the egg, you get 46 chromosomes (diploid)

Front 38

Genetic engineering

Back 38

is when we change (alter) somethings DNA to change its appearance or behaviour

Front 39

Artificial selection

Back 39

is when we chose which animals will live and reproduce

Front 40

Natural selection

Back 40

is when nature choses who will survive and reproduce (usually the stonger ones survive to reproduce)

Front 41

Selective breeding

Back 41

when we force upon sexual reproduction upon 2 different animals to get a new animal

Front 42

extirpation

Back 42

the process of extirpating or destroying totally,

Front 43

Protected Area's

Back 43

are area's where close to extinct animals go where noone can hunt or harm them. An example of one is Banff National Park

Front 44

Biological Diversity

Back 44

Is the study on how everything living thing lives their lives, what they do inside of their environment, how others live off of others, and how we are made up

Front 45

Speciation

Back 45

The evolutionary formation of new biological species, usually by the division of a single species into two or more genetically distinctinct ones

Front 46

Biotechnologies

Back 46

are technologies that enchance and control biodiversity

Front 47

Bioindicator species

Back 47

Biological indicators are species used to monitor the health of an environment or ecosystem

Front 48

Global treaties

Back 48

A treaty is an express agreement under international law entered into by actors in international law, namely sovereign states and international organizations.

Front 49

Transgenic

Back 49

An organism whose sperm or egg contain genetic material originally derived from an organism other than the parents or in addition to the parental genetic material.

Front 50

Seed Banks

Back 50

A seedbank stores seeds as a source for planting in case seed reserves elsewhere are destroyed. It is a type of gene bank.
