Scientific method
What is a control group?
Group/samples under normal circumstances
What is oxidation?
Giving away electrons
What does hydrophobic mean?
Doesn't dissolve in water
What is transpiration?
Water evaporating out of plants
What is nitrates and ammonia from?
factory pollutants
What is an independant variable?
What the researcher changing/testing?
(x axis)
What is an ionic bond?
Giving or losing electrons
What is a hypertonic solution?
More water in of cell/Cell shrinks
What stops water when traveling underground?
impermeable barriers
What causes sulfate to enter the water?
Eroding rocks and soil
What is a constant?
Factors that remain the same in both the control and testing groups?
What is a polar covalent bond?
unequal sharing of electrons
What is an isotonic solution?
Same percent of water inside and outside of the cell
What happens to water when the soil has a high porosity?
The water moves quickly
Effects of drinking water with ammonia?
Changes acidity(pH) of the blood
58dg = ?cg
580cg
The most common electronegative elements
N (nitrogen)
O (oxygen)
P (phosphorous)
What is a hypotonic solution?
More water out of cell/water moves into cell
What is eutrophication?
The deadening of a waterway
-Often caused by algae overgrowing and dying from nitrogen runoff
-Decomposers break down dead stuff and use all the oxygen
