The four butterflies in the illustrations represent the offspring in the F1 generation.

Which statement is best supported by the phenotypes of these offspring?

The 1918 influenza epidemic killed between 50 million and 100 million people worldwide. This epidemic happened near the end of World War I. More people died from the influenza epidemic than were killed in the war. Which of the following explains why this virus was so deadly worldwide?

The amount of energy the producers in this energy pyramid provide the primary consumers is 54,000 joules. From this amount, 540 joules are provided to the tertiary consumers.

Based on this model, how much of the energy was provided to secondary consumers?

The diagram represents one way an enzyme can be inhibited.

Which statement explains the effect of an inhibitor on an enzyme?

Four different nucleotides are used as building blocks of DNA. Which of the following can be used to distinguish one nucleotide from another?

The green frog (Lithobates clamitans clamitans) is found in many parts of the United States. The table contains some information about this frog.

Why does the ability to lay 1,000 to 5,000 eggs increase the fitness of the species L. clamitans clamitans?

During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material —

As a fertilized egg divides, the cells differentiate because they —

Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?

Health professionals sometimes recommend nutritional supplements that contain a variety of species of bacteria to promote good digestive health. The product label for one of these supplements is shown.

Why does this type of bacteria-filled supplement benefit human health instead of causing illness?

The initial steps in gene expression are modeled below. Double-stranded DNA first unwinds into two strands.

Which process and product are represented in Diagram 2?

During ecological succession, how does the growth of young hardwoods affect the organisms living in an ecosystem?

Human bone, muscle, and nerve cells all contain the same number of chromosomes with the same complement of genes. What enables these cells to perform specialized activities?

Some relationships between different organisms are shown in the table.

Which table correctly identifies each type of interaction described?

Cytokinins are a class of plant hormones that help regulate growth by promoting cell division. Cytokinins are produced mainly in meristematic tissue, where most plant growth occurs. Which system carries cytokinins produced in the roots to the rest of the plant?

A prey population consists of individuals with a variety of running speeds.

The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them —

Nitrogenous bases are located on both strands of the DNA double helix. What is the significance of the nitrogenous bases?

This diagram shows cellular activity across a cell membrane.

Which two processes does this diagram most directly model?

In the early 1980s scientists were able to produce two biomolecules by splicing a human gene into the bacterium E. coli to make recombinant human insulin and growth hormone. Which statement best explains why this experiment was successful?

Kidneys are part of the excretory system in a human body. They purify the impure blood and send it back to the rest of the body. Which system is mainly responsible for the transport of plasma to the kidneys?

Part of a hydrothermal vent food web is represented in the diagram.

Which organisms are both secondary and tertiary consumers in this food web?

Five general characteristics of organisms in kingdoms Plantae or Fungi are listed in the box.

Which table correctly lists the characteristics of the organisms in the two kingdoms?

Several structures work together to allow flowering plants to reproduce. The diagram shows a typical flower.

Which table correctly identifies the function of each structure or group of structures in the reproduction of the plant?

Cells pass through a G2 checkpoint before entering mitosis. Ideally, if DNA damage is detected, the cells do not enter mitosis until the damage is repaired. Why is DNA damage repaired before cells enter mitosis?

The table shows a DNA sequence and three types of mutations that can change the DNA sequence.

Which mutation will cause translation to stop?

The picture shows a 3-D model of a virus called a bacteriophage. Bacteriophages can infect bacteria such as E. coli.

In what way are the bacteriophage and E. coli alike?

This dichotomous key can be used to identify some conifers.

Based on the key, which of these best describes the leaves and cones of the longleaf pine?

The complex carbohydrates pictured below are made by linking molecules of glucose.

In all three complex carbohydrates, the subunits of glucose are bonded together differently. Because they have different structures, they most likely —
