Substances or solutions with high concentration of hydrogen ions (H+) also tend to have low PH (0-6) values.
Substances or solutions with high concentration of hydrogen ions (H+) also tend to have high PH (8-14) values.
Nonpolar molecules cannot form any hydrogen bonds with water, so those molecules are
Polar molecules can form any hydrogen bonds with water, so those molecules are
Process to sort the fragments. Electrical current draws fragments through gel. Sorted by size smallest fastest/ first, large at top near wells
Examples of genetic modified organisms (GMO)?
If you can have babies then it is a species, but if you can't then it is not a species.
Derived from same body part present in ancestor. (ex: body limb)
Similar looking structure in unrelated lineage (ex: insect wing & bird wing)

Conditions in nature determine which kinds of individuals in a population are the most fit.
When organisms act like other either to hide from predators, or be the predator & obtain food.

Prevent zygotes from developing into normal individuals (ex: mules - hybrids)
