|what are the first two criteria for life||
A. All life forms contain Deoxyribonucleic acid, which is called DNA.
B All life forms have a method by which they take energy from the surroundings and convert it into energy that helps them live.
|what are the last two criteria for life?||C. All life forms can sense changes in their surroundings and respond to those changes.
D. All life forms reproduce.
|what does DNA provide to a living organism||DNA provides the information necessary for life.|
|does DNA store its information more efficiently or less efficiently than a computer?||DNA stores information more efficiently than a computer.|
| DNA is made up of two basic parts: the backbone and the nucleotides.
A- which part stores the information
B- which part forms the double helix structure
|A Nucleotides store information
B The backbone forms the double helix.
|Which nucleotide will link to adenine? which will link to cytosine?||Thymine will link to adenine and guanine will link to cytosine|

|what is the name of the chemical that plants store their food as?||Starch.|
|what is a biosphere?||a biosphere is where you have a living system that is isolated from its surroundings and its sat_flash_1s continue to live and grow.|
|metabolism requires food and something else. what is that something else?||Metabolism requires food and water|
|metabolism produces energy and usually two other things. what are they?||. Water and carbon dioxide will also be produced.|
|an organisms recptors no longer work. which of the four criteria of life will the organism not be able to perform||A organism will not be able to meet the third criteria for life, all life forms can sense changes in their surroundings and respond to those changes.|
|consider the diffrence between a shark and an anchovy. both are fish. the first is a fierce hunter that is rarely eaten by any other animal. the second is a major source of food for many other fish in the sea. which would you expect to have more babies?||two anchovy parents.|
|every once in a while a female cat will be born sterile this means the cat cannot have kittens. does this mean that the cat is not alive, since it cannot reproduce?||the cat will still be considered alive since most of its kind will be able to reproduce.|
|Is the population of people on this earth becoming a problem?||the population on earth is not a problem|
|how many basic kinds of cells are there?||There are three basic kinds of cells.|
|if a scientist uses a microscope to examin a cell from a mouse, a cell from a leaf, and a cell from a cat, how many diffrent basic kinds of cells will she see?||The scientist will see two different kinds of cells.|
