Biology Review 1

This question has two parts. Between 2005 and 2016, the Kenai Fjords in Alaska experienced an increase in exposed rock due to melting ice. These rock formations are known as "nunataks," which are the tips of mountains that were left uncovered by glaciers in the last ice age. Part A Which timeline describes how plant diversity on the nunataks will change over time?

• (1st) Mosses completely cover rock-->(2nd) Small shrubs grow between cracks of rock.--->(3rd) Small trees become rooted in the soil.

• (1st) Small shrubs grow between cracks of rock.-->(2nd) Mosses completely cover rock-->(3rd) Small trees become rooted in the soil.

• (1st) Small shrubs grow between cracks of rock.-->(2nd) Small trees become rooted in the soil.--> (3rd) Mosses completely cover rock

• (1st) Mosses completely cover rock-->(2nd) Small trees become rooted in the soil.--->(3rd) Small shrubs grow between cracks of rock

Which statements best compare the function of an ATP molecule to a DNA molecule?

• ATP carries and transmits the genetic information of organisms./DNA serves as a biological catalyst that speeds up the rate of chemical reactions.

• ATP provides energy for chemical reactions in the cell./DNA carries and transmits the genetic information of organisms.

• ATP serves as a biological catalyst that speeds up the rate of chemical reactions./DNA acts as a structural sugar in the cell walls of plants.

• ATP acts as a structural sugar in the cell walls of plants./DNA provides energy for chemical reactions in the cell.

Which cellular function of carbohydrates and lipids should be placed in the shared section of the Venn diagram?

• Hormone production
• Structural support of cell walls
• Energy storage
• Catalyst for chemical reactions

Which pair of statements best compares the primary functions of the carbohydrate chitin and the protein chitinase

• The chitin in the exoskeleton provides support and protection for insects and the chitinase provides support and protection to insectivorous bats

• The chitin in the exoskeleton provides insulation for insects and the chitinase stores genetic information for insectivorous bats

• The chitin in the exoskeleton provides support and protection for insects and the chitinase breaks down the chitin for energy to be used by insectivorous bats

• The chitin in the exoskeleton breaks down for energy to be used by insects and the chitinase provides insulation for insectivorous bats

Answer explanation

The chitin in the exoskeleton provides support and protection for insects, while the chitinase breaks down the chitin for energy to be used by insectivorous bats.
