Term
____ is a reaction to protect your skin
Definition
tanning
Term
makes you more susceptible to cancer? (2)
Definition
Frequent tanning and family history
Term
Where is UV strong? (name3 )
Definition
higher altitudes, ozone hole (southern hemi), non cloudy days
Term
2 parts of skin, and order of depth?
Definition
epidermis and dermis
Term
what happens is the basal cells?
Definition
basal cell carcinoma
Term
most common skin cancer (90 percent)
Definition
basal cell
Term
What does basal cell carcinoma look like?
Definition
small shiny bumps, stays local
Term
2nd most common skin cancer
Definition
squamous cell
Term
Tell me about squamous cell.
Definition
common with darker skin, red patch with well defined outline, rarely spreads, alsered in drs office
Term
now melanoma.
Definition
most dangerous and least common, young age, most dangerous, let's re emphasize that again, surgery for to go away. looks like a mole.
Term
CUE CELL DIVISION
Definition
yes
Term
3 reasons for cell division
Definition
growth, regeration, heals wounds
Term
cell cycle.
Definition
interphase and mitosis (prophase, metaphase, anaphase and telophase)
Term
Interphase, first step
Definition
G1 phase- most rapid growth, makes many many proteins
Term
2nd step of interphase
Definition
either recieves chemical signal and heads onward passed the (SECRET) or is sent to the G0 phase.
Term
g0 phase? fill me it honey!!
Definition
cell is just chillin waiting for a signal to keep splitting.
Term
R point
Definition
r for restriction cuz there aint no goin home after dis girl!!! must finish cycle
Term
AFTER THE R POINT??? THE MOVIE ENDED!!!! WHAT HAPPENS???
Definition
the S phase, fool! where DNA is replicamated. the original and the copy are joined by a centromere. from this: I to this: X
Term
THEN WHAT!!! I AM DYING TO KNOW!!!
Definition
g2 phase, you fattie. there's lesser growth, macromolecules are copied slower (there aint no rush no more!!!) and soemting about proteins and lipids and rna.
Term
ONWARD TO MITOSIS. FIRST PHASE PLEASE.
Definition
Prophase- chromies thicken and become more visible. spindler fibers form. nuclear envelope and membrane are disappearing. doubled chromies (X) move towards center. Centrioles move toward opposite poles.
Term
NEXT.
Definition
Metaphase- Chromies have migrated towards the equator of a cell, moved by the SPINDLIES OF COURSE. that's it, they're just chilling waiting for mr !)(#$&!%P@#_(% to occur.
Term
KEEP GOING, I'LL MOST LIKELY KILL YOU IN THE MORNING.
Definition
Anaphase- Centromeres split and chromatid and sister chromatid separate. BUT WAIT. now they're called chromosomes. a twist! one copy of each goes each way.
Term
THE LAST, IF YOU DON'T COUNT ($&%&&%*$^)(!@@#*&^
Definition
Telophase- Chromies have reached opposite sides, decondense and once again take on a thread like appearance (chromatin). Splindlies dismantle and nuclear membrane and stuff reforms.
Term
the legit last one
Definition
Cytokenesis- diffusion of cytoplasm? in animal cells, cell poinches at the surface and micro filaments form a band and tighten. plant cell- cell wall builds between the 2. vesicles form cell membrane by attaching together to form a plate which attaches to cell wall, causing cyto to divide
