Question

1.What are the six elements of living organisms, and where does each occur in the enviorment? In the four cases, identify the specific molecule that the element comes from?
2.Give a simple description of what is the happening to the six key elements in the course of growth and decay.
4.Give five examples that demostrate different conversions among forms of kinetic energy. Give another five examples that demostrate conversions between kinetic and potential energy

I lost my book
I already lood it up at wikipedia
but can find it there
please tell me a page where i can find info

Answer 1

I think you should look over your notes and use your textbook to find all of these answers. But there is a way to memorise the 6 elements. Just remember CHNOPS, said like Schnappes's, which stands for Carbon, Hydrogen, Nitrogen, Oxygen, Phosphurus, and Sulfur.


Ok. You should look here instead...

For the last question, kinetic energy is working and potential energy is stored. So think of examples...like calories stored as fat get converted to energy when you exercise.

Answer 2

a million. climate substitute is purely what it says - substitute of climate. that isn't approximately one undesirable wintry climate or a warm summer season, that's a metamorphosis to undemanding climate varieties over the long term (i.e. an prolonged time or extra) 2. there are diverse motives. Shake, Rattle and Roll are transformations in our orbit with reference to the solar and alignment to the solar impact climate and relate to ice an prolonged time. dirt interior the ambience led to by making use of volcanic activity, aeroplanes and somewhat large meterorites hitting the earth impact the climate. differences of particular atmospheric gases including CO2, methane, CFC's etc adjust climate. transformations in albedo (the reflectivity of the earth's floor) impact climate, case in point in case you break a large component to rain wooded area, the land turns into extra refelctive to the rays of the solar, or overgrazing in semi wasteland aspects is comparable. 3. lots i don't be responsive to. i'd want to be responsive to all of it yet no one would ever be waiting to soak up that lots information. i'd want to be waiting to quote and reference from many of the main scientific papers to try against people who examine some allegation in a newspaper and choose the entire theory is faulty, or people who say by way of fact this wintry climate grew to become into chilly in one small component to the international, there is no warming globally. 4. As above, those with a small quantity of awareness latch onto one piece of information interior the media and think of it disproves an prolonged time of analyze. In any large form of folk there'll constantly be a minimum of person who's a chancer or nook-cutter - it does no longer propose that any of the others are, and if one mistake is made it does no longer propose that each and every thing else with reference to the subject rely is a %. of lies or government conspiracy. that's a pity those minor hiccups get highlighted interior the media and a few people undertake it by way of fact the entire photograph while that's a special to insignificant element. 5. sure, very lots and have been for over two decades. What I discovered interior the Nineteen Eighties is beginning as much as ensue now.

Answer 3

uh oh - looks like someone skipped class again !

Answer 4

Cheater. Look it up in your book.

Answer 5

read your notes, think and then write.
