    Wow all the time you spent typing this you probably could have ANSWERED THE QUESTIONS YOURSELF sheesh dont you have a textbook or somthin

    2) idk

    8)is it a hypothesis

    9)idk

    10)idk what it is called by the highest magnification is the 40x Lens and it magnifies 400 times

    11)idk

    13)homeostasis

    14)population is how many of each organism and an ecosystem is a community of organisms and their abiotic environment

    15) idk but I think that is the most commonly used microscope

    16)all the time so you never get hurt

    17)idk

    18) water

    19)solute is dissolved in a liquid to make a solution a solvent is a liquid that dissolves other substances and a solution is homogeneous mixture of two or more substances uniformly dispersed throughout a single phase

    23)photosynthesis (reactants) 6 CO2 + 12 H2O yields (products) C6H12O6 + 6H2O +6O2 cellular respiration (reactants) C6H12O6 + 6O2 yields (products) 6CO2 + 6H2O {all the O are ooooos not zeros}

    27) ive never heard of them

    33) my best guess is DNA

    35) because the cells divide a lot and they have cell walls, maybe

    36)the cell wall

    37) diffusion- a substance of higher substance moves to an area with lower conceration, osmosis- when water diffuses through the cell membrane only water is osmosis facilitated diffusion is diffusion across the cell membrane with the help of carrier proteins with the concerntration gradient active transport- the movement of molecules against a concerntration gradient

    38)idk

    39)it becomes ADP

    41)lactic acid produces acid and alcohol fermentationproduces ethyl alcohol and Co2

    42)anerobic goes without oxygen present and aerobic goes with oxygen present

    44) idk

    51) idk

    52)idk

    53)idk

    59)idk

    60) 46

    61) idk

    62) Xy boy XX girl

    63) idk

    64) idk

    I hope that this helped and good luck

    The structure is very cool... What you neglected to address, however, was the fundamental difference between environment. A wood floor's ambiguous and impersonal to the foot, sock or no sock. But who's going to wear socks in a bathroom? Who stays barefoot in bed? Who can eternally choose between two basic needs of the foot? This is a deep societal issue! You cannot generalize about such things! Your question is akin to comparing preferences between Dove and Hershey chocolate--IT CANNOT BE DONE! THIS IS BLASPHEMY!!! Come and ask this again when you have gained a sense of propriety concerning such matters. I command it. So let it be written. So let it be done.

    9. pose a question, hypothesis, research, data, conclusion

    16. when conducting experiments

    19 solute is what gets dissolved, solvent is what dissolves the solute and solution is the mixture with a solvent and a solute [[i think]]

    36. cell wall

    62 x and y

    that's all i've got, check a science book

    well they are all easy so you should do them your self most people don't want to do a 7th graders homework

    a pedigree shows how traits are passed form family members and using symbols (squares, circles) either shaded or non shaded to show the traits or characteristic.

    If you didn't get any of those then perhaps you should consider doing a different class, or even doing some study!!

    Try a new invention its called studying.
