obsession

cannot tahan already.
studying the whole animal kingdom
make me wann puke.
i cannot take it anymore.
i still have to go and refresh memory.
wah my cnidarian still rusty. i have no idea
how the cloody anthazoans manage to make corals.
i noe one is internal skeleton
the other one is external skeleton.
how i dont know.
porifera i wish it come out cause i damm power
so are my worms. annelida, nematoda and the platyhelminths
but my chaetopterus still rusty ah.
what modified aliform???
and then my arthropods.
they have tagmatization
and the process of moulting let me see.
the hypodermis?? secrete proenzyme inactive form
and then the endocuticle breaks and then ah forget.
hmmm and then my mollusc gastropods exhibit torsion
which is the counter clockwise 180 degree rotation of head and foot
relative to the shell, body (viseral mass)
why it happes?
because the abductor muscles develops faster
in the embroyonic stage.
why???
scientist not sure advntage: viceral mass at anterior region
protection so head can entert the shell first
but the anus is at anterior region
serious sanitation problem
and then still got my echinoderms.
i remember the structure of WVS
and the Aristotle Latntern from the sea urchins
for feeding got 5 teeth to scrape food
then the defence sstem of the blody sea cucumbers

oh still havent finish
got diong's part
i think avian flight will come out.
I NOE HOW BIRDS FLY!!!
basically, because of the cambered wing structure
so bernoullis principle
the air current flows faster at upper wing
surface compared to the lower
region of wing so generates lift (high pressure to low pressure)
and then also got the angle of attack
beyond 15 degrees the blody bird will come to a stall
and must regain proper angel position otherwise
it will crash.
and then the drag forces cause the bird to move backward
but lift cause bird to move upward.

how the bloddy bird is adapted to bipedalism and flight???
bones baby bons
too many reason
let me see....

pneumatic bone
kneeled sternum for attachment of pectoralis muscle
aiyoh too many cant remember.
and then still have how my turtle heart pump blood
turtle is my personal best
2 seperate atrium
one ventricle
devidid in portions
cavum pulmonale, cavum arteriosum, cavum venusum
then still gotr the right to left cardiac shunt
and left to right for crocodile
for what thermoregulation purposes
then then still got the snake tegument stucture
wah too many i dont know i shall continue
hurting my poor brain.
and i havent touch the blardee nerve for 204 die die die.
