CHIONGING SCIENCE NOW!!!
got three TOPICS!!!
BIOLOGY PHYSICS CHEMISTRY
OMG!!!
OK!!
ii SHALL practice HERE...
hahas...
wad is contraceptiions..?
contraception is the temporary method to prevent unwanted prenancy...correct?
OMG!!! WRONG!!
it is the DELIBERATE PREVENTION OF PREGNANCY!!!
OMG!!! I GOT WRONG!!!
siiao liiaox...
wad is diffusion...
diffusion is the net movement of molecules from a region of higher concentration to a region of lower concentration with or without the presence of the partially permeable membrane...
YEAHH!!! CORRECT!!
wad is osmosis?
osmosis is the net movement of water molecules from a region of higher water potential to a lower water potential with a presence of the partially permeable membrane...YEAH!!! CORRECT!
okok...next...
what will happen to a plant cell when it is soaked in a hypotonic solution...
the cell will become TURGID...there is a flow of water from the water in the surrounding to the cell vacuole...then plant cell would not burst because it has a cell wall to protect it from bursting...WEEE!!! correct!!
ok...
name me 4 temporary contraceptions...?
condoms birth control pills IUD(intrauterine device) and spermicidies...
correct!!
name me the two permenant contraceptions...
the vasectomy and ligation...
vasectomy the doctor cut the sperm duct and ties it...it prevents the sperm from
travelling from the storage duct to the urethra...WEE!!!
LIGATION is the doctor will cut both the fallopian tubes and tie them...it prevents the ova to move from the ovary to the uterus...OK!!
wad is STDs...?
sexual transmiitted diseases...
3types...gonorrhoea syphilis and HIV!
the symptoms are
GONORRHOEA-
is for guys...burning sensation when passing urine and pus will be discharged from the penis.
for ladies...no symptoms...abdominal pain due to the infection of the fallopian tube...infected babies will be blind...
SYPHILIS-
early stage painless sore ..may or maynot develop non itchy rash...
later stage...paralysed...deformed joints insane or which lead to death...
infected babies will result in abnormal teeth bones and deafness...
HIV-human immuno-deficiency virus
early stage no symptons bady system fall sick easily and require a long time to recover.
later stage-severe diarrhoea.PROLONG fever night sweats loss of appetite loss of weight and 8-10years later AIDS(acquired immuno-deficiency syndrome) whole immune system gets weaken and disease like pneumonia dementia thrust brain infection and kaposi's sarcoma...
HOW DOES AIDS SPREAD?
AIDS is spread by the sharing of needles from a infected person...
having sexual intercourse with a infected person...
blood tranfusion through an infected person...
HOW TO PREVENT! befaithful to only one sex partner...
avoid sharing of personal items with others and go to a reliable hospital for blood tranfusion...
WHERE IS BILE PRODUCED...
BILE is produced in the liver...
it is STORED in the gall bladder...
name me THREE ART!
GIFT(gamete intra-fallopian transfer) ZIFT(zygote intra fallopian transfer) IUT(intra uterine transfer EXTRA IVF(in-vitro fertilisation)
where are the THREE TYPES of enzymes FOUND?
the carbohydrases proteases and lipases are found in the SMALL INTESTINE..
carbohydrases break down carbohydrates to simple sugar
protease break down proteins into amino acids
lipases break down fats to fatty acids and glycerol
wad is the USE of BILE?
it is used to emulsify fats into fat droplets...
then PANCREAS PRODUCES pancreatic JUICES which is made up of the three enzymes...
in the BIG intestine
NO DIGESTION! and only absorption of water and mineral salts...
OKOK!!! I HAD ENOUGH!!!
ii GO STUDY WITH EUNICE LERH!!!
KIIES!!!
GTG!!!
CHIONG SCIENCE!!!
hahas...
CANNOT FAIL!!!
ALL THE BEST GUYS!!!
TAKE CARES!!!
