Which statement best describes the event shown in the diagram?

• A. Glucose is being synthesized in the chloroplast using nitrogen from plants.

• B. Amino acid monomers are joining together to form a protein macromolecule.

• C. A polymer in the nucleus is being broken into its individual monomer subunits.

• D. Lipid molecules are forming fatty acid chains in a dehydration synthesis reaction.

The title of the diagram is, Cellulose Model. The diagram shows a chain consisting of multiple three-part sequences of a rectangle connected to a hexagon connected to the letter “O”. There are six rectangles, six hexagons, and five “Os” shown. Cellulose is a carbohydrate and a polymer of glucose. Which statement best describes how cellulose is formed within living organisms? (the state forgot the image, I found a similar one I think)

• A. It is assembled by bonding individual atoms.

• B. It is constructed by connecting smaller monomer subunits.

• C. It is the product of the decomposition of a much larger molecule.

• D. It is the result of a physical change that alters the shape of a compound

Many plants have a waxy coating on their leaves. Which statement describes the most likely structure and function of the waxy coating?

• A. The waxy coating is a protein that can help attract other organisms for pollination.

• B. The waxy coating is a protein that can help release waste molecules during transpiration.

• C. The waxy coating is a lipid that can help absorb more sunlight in hot environments.

• D. The waxy coating is a lipid that can help prevent excess water loss in dry environments.
