Thrips are insects that feed on the pollen and flowers of certain plants. The size of a thrip population depends on the number of flowers available. Which graph best represents changes in a population of thrips if winter was longer than usual and the summer was too cool and dry for many flowers to bloom?

• 
• 
• 
• 

The percent of DNA that species A has in common with species B, C, D, and E are shown in the graph below. Which statement is a valid conclusion that can be drawn from this graph?

• Species A is closely related to species B, but is not related to species E.

• Fewer mutations have occurred in species B and C than in species A.

• Species A and E have the greatest similarity in protein structure.

• Environment influences the rate of evolution.

Base your answer on the passage below and your knowledge of biology.

Corals come in about 1,500 known species - from soft swaying fans to stony varieties with hard skeletons that form reef bases. They are made up of polyps, tiny animals that live in colonies and feed at night on microscopic plants and creatures. The coral's surface is the living part, with color infused by single-celled algae called zooxanthellae that live in polyp tissue. The algae act like solar panels, passing energy to the coral as they photosynthesize while feeding on the coral's waste.

Extremely sensitive, corals survive in a narrow range of temperature, sunlight and salinity. An uncommonly severe El Nino in 1998 raised ocean temperatures and changed currents, causing bleaching that devastated reefs worldwide. Scientists say parts of the Indian Ocean lost up to 90 percent of corals. The bleaching struck reefs around the Persian Gulf, East Africa, Southeast Asia and the Caribbean. Some recovered. Many died

The relationship between the polyps and the zooxanthellae can best be described as

• negative for both

• neutral for both

• positive for both

• negative for one and positive for the other

How do processes 1 and 2 affect the amount of genetic information provided by a parent to its offspring?

• Processes 1 & 2 doubles the amount of genetic information during the production of egg and sperm.

• Processes 1 & 2 reduce the amount of genetic information by half during the production of egg and sperm.

How does process 3 affect the amount of genetic information an offspring receives?

• Process 3 restores the species number of chromosomes, giving the offspring one full set of chromosomes.

• Process 3 reduces the number of chromosomes in the species

• Process 3 doubles the normal number of chromosomes in the species.

• Process 3 quadruples the species number of chromosomes in the species.

Which diagram indicates the areas where each of these substances would be located after 20 minutes?

• 
• 
• 
• 

Which phrase could be used to describe this technique?

• the use of chromatography to separate molecules in a mixture

• the use of cut leaves to observe certain colors

• using indicators to determine pH

• using dichotomous keys to identify plants

The ability to grow in size is a characteristic of living organisms. Although an icicle may grow in size over time, it is considered nonliving because there is

• an increase in matter, but no increase in the number of icicles

• an interaction between the icicle and the environment

• no way for the icicle to move away from heat

• no metabolic activity present

Which cell structure is correctly paired with its primary function?

• ribosome–protein synthesis

• mitochondrion–movement

• vacuole–cell division

• nucleus–storage of nutrients
