Biology Midterm Review

Water has many several important properties. Which two of these properties cause water to have surface tension?

• Heat capacity and cohesion

• Solubility and density

• Density and adhesion

• Cohesion and adhesion

Why do invasive species cause native species to become threatened?

• Invasive species have no impact on native species
• Invasive species outcompete native species for resources
• Invasive species help native species find more resources
• Invasive species provide protection for native species
