light is a .... wave
transverse
properties of sound and waves
-vibrations that propagate through space as waves
-source is something vibrating
-carry energy

optic nerve
carries messages from the eye to the brain
divergant lens
another term for concave
cornea
transparen sheet at the front of the eye that bulges outward slightly
pupil
this part of the eye is not an actual structure
vitrious fluid
transparent jelly-like substance that fulls the entire back cavity of the eye
fovea
the region on the treina of most distnict visoin
iris
expands and contracts to control the amount of light entering the eye
pitch
the relative highness or lowness of a sound

determined by the frequency of the sound wave
frequency
# of waves coming at source per second
descirbe how various animals see different and hear diferen
some see colors differently-snakes in infared and dog+cat in black and white
what is light and how does it travel
transversal wave that travels without a medium
how does an image look on our retina
upside down
rods
and
cones

are located in?
rods: sensitive to dim light and movement; cant see in color.

cones: sensitve to brigh light and color and are able to make out fine detail

lens
lens
bends light that passes throught the cornea and pupil so that it comes to a focus on the retina.
iris
colored part of the eye
what fixes nearsightedness
what cause it
convex
eye to narrow
what fixes farsightedness
what causes it
concave
eye to thick
farsightedness
ibjects at distant are seeon clearly while near objects are out of focus
auditory nerve
carries meggases from the ear to the brain
DNA
controls the cell
instructions for life
twisted later
a t c g
Gene
a segment of DNA that codes for a protein which codes into a trait
mRNA
used to read DNA in nucleus because DNA is to big to fint through pores

carries info from DNA in nucleus to the ribosomes for protein synthesis

TRANSCRIPTION
tRNA
TRANSLATION

RNA molecuels transport amino acids to ribosomes to be translated
transcription
making mRNA in nucleaus from DNA code

DNA-RNA
translation
builds proteins from amino acids

RNA makes sequences of amino acids on ribosome to form protein
nucleaus
control center
contains DNA
Mitosis
multiply cells
replace dead cells
miosis
sex-mixing genes of diff. genes of diff. orgainisma of same species

making cells with half the numebr of chromosomes
allele
version of trait or gene
C=curly hair
c=straight hair
dominate
trait that shows even when one is present
recessive
trait that shows only when paired with another recesive
genotype
what the gene looks like

AA. Aa. aa
phenotype
physical apperance of gene

curly/straight hair
Karyo
nucleaous (of cell)
type
representative of..
di
two, twice
zygous
pairing (of chromosomes)
hemo
