A student is sweating after playing basketball.

Which body systems are MOST DIRECTLY interacting as a response to maintain homeostasis?

• Digestive and circulatory systems

• Immune and integumentary systems

• Nervous and integumentary systems

• Circulatory and nervous systems

Which organ and tissue interact MOST DIRECTLY to absorb and transport water and dissolved minerals inside a plant?

• Flower and phloem

• Root and phloem

• Flower and xylem

• Root and xylem

A student compares two different species of fox as shown in the table.

The student wants to explain why the two species are so different

even though they have a common ancestor.

Which statement BEST explains the differences between the two species?

• Different environments led to different adaptations.

• The same environment led to different adaptations.

• Each species developed the same adaptations to

  different environments.

• Each species migrated to environments that matched

  their adaptations.

Which statement BEST describes how enzymes affect the speed of a metabolic reaction?

• Enzymes increase the concentration of reactants, which increases the speed of the reaction

• Enzymes decrease the energy needed to start a reaction, which increases the speed of the reaction.

• Enzymes replace the reactants in a chemical reaction, which decreases the speed of the reaction.

• Enzymes prevent products from being converted back into reactants, which decreases the speed of the reaction.

Which molecules are the building blocks of DNA?

• Proteins

• Fatty acids

• Nucleotides

• Chromosomes

Which plant structures are DIRECTLY involved in the production and transport of glucose?

Select TWO correct answers.

Answer explanation

the leaves conduct photosynthesis and the stem/phlem transports it around the plant

A Venn diagram comparing the functions of proteins and nucleic acids is shown.

Which functions BEST complete the Venn diagram?

Select the correct answer for each box. Not all answers will be used.

b

c

d

transport substances

Are involved in translation

Provide energy

encode genetic information

are stored as glycogen

provide insulation

Answer explanation

proteins help with cell transport (facilitated diffusion)

Which table correctly matches each type of biomolecule with its function in the cell membrane?

• 
• 
• 
• 

Which statement BEST describes the roles of glucose and oxygen

in photosynthesis?

• Glucose releases chemical energy during photosynthesis, and oxygen is a product of photosynthesis.

• Glucose releases chemical energy during photosynthesis, and oxygen is a reactant in photosynthesis.

• Glucose stores chemical energy during photosynthesis, and oxygen is a product of photosynthesis.

• Glucose stores chemical energy during photosynthesis, and oxygen is a reactant in photosynthesis.

Biting flies can transmit diseases and cause loss of blood for animals

in nature. Horses have developed behaviors to repel biting flies such

as ear twitching, head tossing, leg stomping, and tail swishing.

Which statement best describes the interaction between body systems

that allows horses to repel biting flies?

• The nervous system senses the biting flies and sends a signal to

  the muscular system to move.

• The circulatory system senses the biting flies and sends a signal to

  the nervous system to move.

• The muscular system senses the biting flies and sends a signal to

  the integumentary system to move.

• The integumentary system senses the biting flies and sends a

  signal to the circulatory system to move.
