Thought the mayfly nymphs bit was really hard- also the measles stuff.
1) about the bacteria fixing and lightning
2) then i talked about plants use nitrates for their protein- not sure about that
3) then i said that plants than eaten by animals and they get nitrates
4) excretion of urea that change into ammonia then it goes back to the soil by nitrifying bacteria
Thats it.... i just wrote the whole thing about the nitrogen cycle so i will pick up some marks hopefully....
also one of the sixth mark qs about the heart disease....i talked about the coronary heart disease- CHD built up fat around the arteries and make it hard to circulate the blood around the body.... blah blah blah
also leo i think that was the name... had heart attack because of unhealthy diet, smoking, and lack of exercise that leads to this condition.
cant remember of his brother name but he didnt get heart attack even if he is older because he is healthy, does exercise and living healthy life style.......
thats it i am not gonna write about the triplets one- all i know that a zygote splits into 2 and therefore identical a and b.... blah blah
