This type of carbohydrate is made by autotrophs, like plants, for long term energy storage

• glycogen

• cellulose

• starch

This carbohydrate is used for when extra glucose is needed quickly in animals. It's also stored in muscles and our liver

What is adhesion in water molecules?

• When water sticks to other water molecules

• When water sticks to other molecules that are not water

• When water molecules are equal on both sides of the membrane

• When water molecules bond together at the surface of a body of water

Describe the orientation of the phospholipids in the membrane.

• Phospholipids orient in bilayer with hydrophilic heads on exterior

• Phospholipids orient in monolayer with hydrophilic head on extracellular

• Phospholipids orient in bilayer with hydrophobic tails on exterior

• Phospholipids orient in monolayer with hydrophobic tails on extracellular

Because of the unique properties of water associated with hydrogen bonding, water evaporates from pores on the leaves of plants and draws water molecules in a continuous chain from the roots up through the vascular tissues of plants. Which of these groups of terms describes the process and the properties of water that explain this?

• adhesion, cohesion, and translocation

• adhesion, cohesion, and transcription

• cohesion, adhesion, and transpiration

• cohesion, hybridization, and transpiration

Which of the following describes why lipids are hydrophobic?

• Lipids are composed mostly of hydrocarbons which are nonpolar

• Lipids have hydrogen bonds that repel the hydrogen bonds in water

• Lipids have more neutrons in their atoms, making the compound neutral

• Lipids are gaseous materials that do not dissolve in water

Which of the following does not result from hydrogen bonding in water molecules?

• Cohesion

• Adhesion

• Surface Tension

• Dissolving fats

Why is water considered polar?

• Nonpolar covalent bonds in structure

• Ionic bonds in structure

• Polar covalent bonds in structure

• Hydrophobic interaction in structure
