Biology Quarter 1 Exam

Experiment #1: Polly Plant wanted to determine the effect that color might have on the photosynthesis rate of plants. She purchased 15 spinach plants of equal size and placed each one in a plastic box. Five boxes were placed under a blue light, five boxes under a red light, and five boxes with natural light. Every 30 minutes for two hours she measured the amount of oxygen.

What is the dependent variable?

• Color of the light

• Plants with natural and color light

• Plants with light

• how well the plants grow

The movement of water against gravity up narrow tubes is _______

• Surface Tension

• Capillary action

• Expansion upon freezing

• High Heat Capacity

Why does this happen?

• Because water is mor dense then liquid water while it expands

• Because ice doesn't weight a lot, and it expands

• Because water is less dense than liquid water which cause a hydrogen bond

• Because water is less dense than liquid water which causes a covalent bond

Why can Water striders walk on water

• It resists an external force, due to the cohesive nature of its molecules

• It resists an internal force, due to the cohesive nature of its molecules

• It resists an external force due to the adhesive nature of its molecules

• It resists an internal force due to the nature of its adhesive nature of its molecules

• oxygen
• soil
• carbon dioxide
• sugar

Ms. Fourth spills water on the floor. After she cleans it up, she realizes that the paper towel absorbed all the water and now the paper towel is all wet. What is this caused by?

• Water's ability to be Cohesive

• Water's ability to be Adhesive

• Water's ability of Capillary Action

• Water's ability to be Cohesive and Adhesive
