Answer:
The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
Explanation:
Water has awesome properties that distinguishes it among all other substances, many of which is attributed to its hydrogen bonding. Liquid water contains hydrogen bonds that holds tightly its molecules. However, when this liquid water freezes, the hydrogen bonds between its molecules break and expands. This creates space for the water molecules to occupy as it turns to its solid form (ice).
This is the case of this ice-covered lake. The ice, when it sinks, causes the liquid water beneath to freeze because the hydrogen bonds between the water molecules are being expanded enabling the molecules to occupy more space (volume) and make it less dense than liquid water (decreased density).
Answer:
When ATP molecules are used to fuel movement.

Answer:
"The population starts to die off to return to carrying capacity."
Explanation:
When a population has maxed out the space it has to live, something has to come to kill it off so the natural balance would be restored. What kills the population can vary. It can be lack of resources, illness, predators, etc.
