4=> the colon's function is to absorb the remaining water from indigestible food matter; to accept and stores food remains that were not digested in the small intestine; and to eliminate solid waste (feces) from the body. so when the colon is removed, these functions are not carried out which may lead to many excretory system problems...

hey again.... i checked out abt dat taxis thing and it says it is restricted in cells that possess any organ having functions related to locomotion (flagella, cilia,etc) which means it can only take place in unicellular organisms lyk some bacteria that dont have flagella... bt in the IGCSE study guide they have taken an example of woodlice in choice chambers!?!?!... m reely confused pls help..

Hi people! I have some doubts in Biology.. I'm appearing for o/n 2012 (IGCSE)
1] explain how variation within one species may eventually lead to the development of two different species. {4marks}
2] Describe the part played by the uterus in the development of an embryo from the time of ovulation to the birth of the baby. {7 marks}
3] Describe the use of fermenters in the production of
i) antibiotics ii)single cell protein {6 marks}
4] what happens to digestion when the colon is removed? {4 marks}

PS- give me as many points as you know... n thnx in advance...

Ans to 1] is NAtural Selection followed by Evolution...m pretty sure of diz
2]Uterus is d moms womb were d baby develops....placenta is an extended organ from uterus....den ri8 bout d fuctions of placenta...during birth uterus causes rapid contractions thus helping baby come out...
3]1)Extra cellular digestion done by micro organisms..so dey secret d product of intrest as well....den d microbodies are filtered.
2)Donno...
4] I told u d ans dat day on chat....
Satisfactory.????
