Answer:
photosynthesis and the erosion of limestone
During the exercise period (10-15min) the blood lactic acid concentration increases to about 13.2 mmol/dL (same units as on graph) as the individual is having problems keeping up their aerobic respiration. After 15min, they stop exercising and the lactic acid concentration starts to return to normal as their body is able to take in enough oxygen and catches up with the excess lactic acid, metabolizing it into CO2 and H2O. The period between 15-20 min shows the fastest reduction in concentration.
When water is transferred from land to atmosphere by evaporation from the soil and by transpiration plants.
Jack should arrange the beads close together and slide past each other to represent water molecules in a liquid.
<h3>How are the molecules of water arranged when water is in its liquid phase?</h3>
- Each water molecule contains two atoms of hydrogen and one atom of oxygen, arranged such that one side of the molecule (nearest the hydrogens) is positively charged while the other side (nearest the oxygen) is negatively charged.
- They’re arranged randomly, and in random motion.
- In fact, they’re not even keeping the same hydrogen atoms, as they are constantly popping off and reforming on the nanosecond time scale.

Answer:
Compounds are made up of elements that are chemically joined. Like elements, compounds have properties that allow us to identify them. Learn about physical properties, like color, odor, melting point and boiling point, as well as chemical properties in this lesson.
