homeostasis
response to a stimuli
reproduction
growth

Front 2

5 kingdoms

Back 2

Front 3

beetle lab

Back 3

insect pest of flour and other stored grain products. the beetles use these grain products for food, living space, and breeding grounds.

Front 4

characteristics of beetle lab

Back 4

short life cycle
small in size
complete metamorphosis
many offspring
easy to care for and observe
may be carnivorous
good model for population studies

Front 6

logistic population growth

Back 6

there are many limitations to population growth (density, competition, predation, and others). these limits are known as the carrying capacity (k) and tend to stabilize population size.

Front 7

in complex population

Back 7

the population size tends to vary above and below the carrying capacity-resulting in a relatively stable population size.

Front 8

compound microscope

Back 8

primary microscope used for cellular and microscopic items which is what we use in lab

Front 9

dissecting microscope

Back 9

used for viewing big pieces

Front 10

transmission microscope

didn't use, used to examine fine detail, a single column of atoms

Front 11

the cell theory

Back 11

1) all living things are composed of cells
2) the cell is the basic functional unit of life
3) all cells arise from previously existing cells

three basic components of a cell

Back 12

cell membrane
cytoplasm
dna

Front 13

cell membrane

Back 13

boundary between interior of cell and external environment

Front 14

cytoplasm

Back 14

everything outside the nucleus and within the cell membrane

Front 15

dna

Back 15

the hereditary material that contains information to direct cell reproduction and other processes

Front 16

prokaryotic

Back 16

no nucleus
no membrane
recognize the cell wall
dna floats around
ribosomes are the only type of organelles
single-celled

Front 17

eukaryotic

Back 17

can be single or multi celled
multiple organelles

Front 18

animals only have ____ not ____

Back 18

cell membranes, cell walls

Front 19

organelles of a typical animal cell

Back 19

nucleus, nucleolus, chromosomes, cell membrane, cytoplasm, endoplasmic reticulum, ribosomes, golgi bodies, lysosomes, mitochondira, centrioles, microtubules, vacuoles

Front 20

what's only present in plants and not animals?

Back 20

cell wall, vacuole, chloroplasts

Front 21

cell wall

Back 21

contains cellulose, gives the shape and rigidity to the cell

Front 22

large vacuoles

Back 22

well developed for storage, small or absent in animal cells

Front 23

plastids (chloroplast)

Back 23

site of photosynthesis; contains green pigment

Front 24

mitosis

Back 24

the division of one cell producing two identical sister cells
only divides somatic cells

Front 25

5 stages of mitosis

Back 25

1. interphase
2. prophase
3. metaphase
4. anaphase
5. telophase

Front 26

meiosis

Back 26

a reduction of division, by which gametes are produced
one cell produces four cells wiht half the chromosome number using two cycles of division
UNIQUE
production of gametes (egg or sperm)

Front 27

cancer

Back 27

a group of diseases characterized by uncontrolled growth and spread of abnormal cells

Front 28

stages of cancer

Back 28

1. initiation- normal cell becomes cancerous
2. promotion- cancer cells divide uncontrollably (tumor formation)
3. metastasis- cancer cells spread to other parts of the body (new cancers appear)
4. death

Front 29

causes of cancer

Back 29

1. environmental conditions
2. radiation
3. viruses
4. hereditary
5. many other causes

Front 30

diagnosis and treatment

Back 30

1. early detection
2. chemotherapeutic drugs
3. radiation therapy

cancer's 7 warning signs

Back 31

1. change in bowel or bladder habits
2. a sore that does not heal
3. unusual bleeding or discharge
4. thickening or lump in breast
5. indigestion or difficulty swallowing
6. obvious change in wart or mole
7. nagging cough or hoarseness

Front 32

benign

Back 32

localized tumor which causes little harm

Front 33

malignant

Back 33

tumor growth continues and destroys other tissues. now considered regional which can slow immunity and cause tumor to spread

Front 34

tumor

Back 34

abnormally dividing cell mass

Front 35

contact inhibition

Back 35

cells cannot respond to the body when it says stop dividing

Front 36

proliferation

Back 36

rapid or excessive spreading

Front 37

a scientific theory is

Back 37

something that has been tested or can be tested

Front 38

personal theory is

Back 38

something that cannot be tested. it is something people assume.
