Forest fires are often started by lightning. In the past, forestry services would extinguish the fires before they spread. Today, many forestry services practice controlled burning of forests. What is the most likely reason forestry practices have changed?

• Controlled burnings return nutrients to the soil.

• Controlled burnings prevent the logging of trees.

• Controlled burnings maintain the population growth of animal species.

• Controlled burnings increase the amount of water runoff after a storm.

Use the diagrams to answer the question. The diagram shows the concentration of different molecules across a lipid bilayer. Which numbered diagram or diagrams represent active transport?

• 1 only

• 3 only

Which property of water helps organisms survive in lakes during cold winters?

• Ice forms a crystalline structure with air pocke

• Ice requires large amounts of heat in order to melt.

• Solid ice is less dense than liquid water, so surface ice insulates the water below.

• Solid ice is white, so it reflects electromagnetic radiation of a range of wavelengths.
