Start off with 2,500 plants of which 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves. Each circle in your simulation will represent 125 organisms. Calculate how many circles you need for each trait, and then create your simulation. Be sure to include a key that states the color coding for each trait.

Molecular models of two different substances are shown below. in the molecule on the left, the oxygen atom pulls on electrons more strongly than the hydrogen atoms. in the molecule on the right, the two oxygen atoms pull on the shared electrons with the same strength. water molecule, h, o oxygen molecule, oz when the two substances are put in the same container, they do not attract each other. why does this happen? a. they both contain oxygen. b. one is polar and one is nonpolar. c . they are both polar. d. they contain different elements.
