Living organism (level of organisation) Life exist in an organised form so as to carry out efficiently the characteristics of living things. Organisation of life is the existence of life from a single-celled organism to a multicellular organism with complex forms that perform different functions Four level of organisation exist :- 1. Cell :- some living exist as a cell capable of carrying out all the characteristics of living things. Eg Amoeba Chlamydomonas Paramecium and Euglena 2. Tissues :- A tissue is a collection of cells which are similar in structure and perform similar functions. Hydra Is an example of animal that is made up of tissues only. examples are blood, epithelial skeletal etc 3. Organ :- An organ is a collection of different tissues that perform a common function or functions . Example of organs are heart, roots, kidney etc 4. System :- A system is a set of organs which co-operate to carry out one vital functions of life. Eg digestive system, reproductive system etc

lol seriously? half of the questions r purely pume questions (jamb usually set these type of questions when they r out to bar students frm getting maximum score in biology.. the jamb professors in charge will be setting questions like "the ability of tasting phenylthiocarbimide indicates what type of variation in humans?" thats why we have to read in between lines. btwn, iam a 300L student of bio/isc in a college of education here(currently posted to a govt skul for my teaching practice, and i wanna try my luck on mbbs).

except question 4 (its under a topic in embryology). Superfetation is an extremely rare phenomena that occurs when a mature egg is produced after conception. Progesteron is actually produced to prevent ovulation when fertilization takes place)

if those re O' level questions, then I need to up my game...

I still got chemistry and physics to work on, now I just found my biology isn't close to what I expected it to be

and its only 1 month remaining... Gosh! I'm so toast

thats nt true, u're gud jor!! no be u dey answer question on resting potential just now? hehe!! Phy is what i wanna start reading! i intentionally delayed it till dis tym so that all d bloody formulars can still be fresh in my head.

Reading between the lines is the best solution.
We student of nowadays avoid and overlook a lot in our textbooks,am very sure 60% of student don't know about rhodopsin,zona pellucida,protandry,glans penis,basilar and tectorial membrane,joints between the three ear ossicles,the list is endless
But all knowledge comes from GOD,you can't be perfect but you can always try to be a near perfect............
