  2. Define molecule.
    Two or more atoms linked together to make a substance with unique properties.
  3. Define photosynthesis.
    The process by which  Green plants and some other organism use the energy of sunlight and simple chemicals to produce their own food.
  4. Define Metabolism
    The sum total of all processes in an organism that convert energy and matter from outside sources and use that energy  and matter to sustain the organisms life functions
  5. Define receptors
    Special structures that allow living organisms to sense  The conditions of their internal or external environment.

  7. Define Alteicial
    A term used to describe offspring that are born without at least one of the following abilities:  here see move about regulate body temperature or eliminate waste.
  8. define cell
    The smallest unit of life in creation.
  9. What are the four criteria for life.
    1.   All lifeforms contain deoxyribonucleic 

    2.    All lifeforms have a  method by which they extract energy from the surroundings and convert it into energy that sustains them. 

    3.   All lifeforms can sense changes in their surroundings  and respond to those changes. 

    4.   All lifeforms reproduce.
  10. What does DNA provide to  A living organism.
    DNA provides the information necessary to make a bunch of lifeless chemicals and turn them into a living system
  11. Compared to other molecules is DNA big or small.
    DNA  is enormous  compared to other molecules.
  12. Does DNA store it's information more efficiently or less efficiently than a computer?
    DNA stores it's information way more efficiently than computers.
  13. DNA is made up of two basic parts: The backbone in the nucleoid bases

     Which part stores the information,?

     Which part forms the double helix structure ?
    1.   The backbone forms the double Helix structure.

     The nucleotide  bases holds the information.
  14. Which nucleotide base  Will link to adenine?   Which will  link to cytosine?
    Thymine  Will link to adenine.   Guanine will link to cytosine.
  15. 1/2 of the portion of DNA has the following sequence: cytosine guanine, adenine,  guanine, thymine, thymine.

     What is the sequence of nucleotide bases on the other half of this portion.
    • Guanine,
    • cytosine, thymine, cytosine,
    • adenine,
    • adenine,
  16. 1/2 of a portion of DNA has the following sequence:


     What is the sequence of nucleotide bases  on the other half of this portion?
    • adenine,
    • cytosine,
    • guanine,
    • thymine,
    • adenine,
    • cytosine.
  17. What is the name of the chemical the plants make for food.
    Carbon dioxide.
  18. What is the name of the chemical that plants often store the food as.
  19. for most organisms,  Metabolism requires food and something else. What is that something else,?
  20. Metaball is him produces energy in usually two other things. What are they?
    Water and carbon dioxide.
  21. An organisms receptors no longer work. Which of the four criteria of life will the organism not be able to perform?
    the organism will no longer be able to sense changes in their surroundings and respond to those changes
  22. Consider the difference between a shark and anchovy. Both are fish. The first is fierce hunter that rarely is 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 offspring's: two shark parents or to anchovy parents?
    The two anchovy parents are more likely to have more offspring.
  23. Every once in a while,  A female cat will be born sterile. This means that the cat cannot have kittens. Does this mean that the cat is not alive, since it cannot reproduce.
    No it does not.
  24. Is the population on this earth becoming a problem?
  25. Indicate what the arrows are pointing at in the cell drawing below:
    A is the organelles

     B is the nucleus 

    •  C  is the cytoplasm 

      D is the membrane
  26. In which  organelle  is most of the DNA stored?
    In the nucleus
  27. How many basic kinds of cells are there? Name them
    • There are three basic types of cells 
    •  The animal cell the plant cell and the bacteria.
