Sugar dissolves in, or mixes completely with water. The solubility of a substance in water is determined by measuring the maximum amount of the substance that dissolves in a given amount of water at a given
temperature. Hypothesis: The solubility of sugar in water increases as the temperature of the water decreases.
What would be the independent variable and the dependent variable that would be used to test this
hypothesis?

What evidence is there that convection occurs in earth’s troposphere?

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e. g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.

Which is an example of a population?
