In Biology there are 8 characteristics a thing needs to have in order to be considered a living thing. Breathing isn't even one of these characteristics. They are as follows:
1. Ability to reproduce
2. Made of cells
3. Homeostasis
4. Responds to the enviornment
5. Can evolve
6. Grow and develop
7. Obtain and use materials and energy
8. Have a genetic code

A tree absorbs carbon dioxide from the air, and, with the input of energy from sunlight, oxidizes many of the oxygen atoms of the absorbed carbon dioxide to elemental oxygen, which is released into the atmosphere. The carbon and some of the oxygen atoms from the absorbed carbon dioxide are incorporated into the structure of the tree as the tree grows.
sugar C6h12O6 , it have many elementsedit: The reason that it is a molecular compound, rather than an ionic compound, is that it contains only non-metal elements; carbon, hydrogen, and oxygen. Also the formula for sugar(sucrose) is C12H22O11.
Chlorine is a chemical element with the symbol Cl and atomic number 17, so it will remain a chlorine atom as it does not "grow up" into a different element. It is used for various applications such as disinfecting water, producing plastics, and in the production of chemicals.
Grass is a solid. It consists of plant material that grows on the ground and has a definite shape and volume.
Even though fire grows and uses oxygen, it is not considered a life form because it is missing some key elements. Fire has neither DNA or RNA, and it doesn't contain any cells. Fire also lacks metabolism and the ability to reproduce.
Fire grows when oxygen (air) gets blown onto it.
As the volume of a cell grows, the surface area grows but not as quickly.
because as you go higher the oxygen grows lighter
fire is considered alive because it needs oxygen to burn. flowers are alive because it needs heat for energy to create more cells, CO2 because they need it to produce necessary sugars. and it grows... of course
E. coli grows better in the presence of oxygen.
the large a business grows the more exposed it is and the involved with the external environment
because the more it grows the more oxygen it needs which could risk its life

(1974) G (2003) PG You should read the book first, though.
the earth maintains oxygen by trees and flowers and other plants that produce oxygen. it maintains it because the seeds from all the plants that produce oxygen get blown away by the wind and get replanted and then after that it grows then another seed gets blown away and another organism grows , its a big cycle that is happening as i type! its quite interesting!!!
Calmly. Explain to him that he is still a little young for relationships with girls and that it will be OK when he grows older. There is nothing wrong in him having a friend that is a girl though. It is normal behaviour.
