Which four body systems interact to allow a person to sneeze?
Muscular, immune, nervous, respiratory
Nervous, respiratory, circulatory, skeletal

- 3. Multiple Choice
Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein.
What is the most likely result if the shape of the enzyme changes?
The substrate will change its shape to match the enzyme.
The enzyme will no longer be able to catalyze the reaction with the substrate.
The products made from the enzyme and the substrate will be changed.
The enzyme will be able to bind to more diverse substrates than before.

Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones to stimulate the growth of shoots.
How are gibberellins able to affect other parts of the plant?
Gibberellins are absorbed through the stomata and attach to chloroplasts.
Gibberellins are transported through vascular tissues to other parts of the plant.
Gibberellins become concentrated within the tissues of the plant during mitosis.
Gibberellins become modified once they infect healthy cells and are later released to infect other cells.

The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants. To protect itself against the ants, it ejects fibers from a tuft located at the tail end of its body. The tufts have hooks at the tips and barbs along their length that lock and interlink with the ant’s setae, small hairs that cover the body of the ant. When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it. As the ant attempts to remove the tufts, it entangles itself more, becoming immobilized.
Which two systems most directly interact in the fuzzy millipede’s defense against ants?
Muscular and integumentary
Immune and muscular
Integumentary and endocrine
Endocrine and immune

A feedback mechanism in the human body is shown. Based on this diagram, which two systems interact to maintain homeostasis?
The nervous and reproductive systems work together to stimulate the production of insulin.
The circulatory and endocrine systems work together to keep blood sugar levels constant.
The excretory and nervous systems work together to convert glycogen into glucose.
The immune and circulatory systems work together to circulate blood through the pancreas.

Which statement accurately describes the energy needs for photosynthesis and cellular respiration?
Solar energy is needed for cellular respiration but not for photosynthesis.
Chemical energy in the form of glucose is needed for both cellular respiration and photosynthesis.
Chemical energy in the form of glucose is needed for photosynthesis, and solar energy is needed for cellular respiration.
Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration
- 10. Multiple Choice
Transmembrane proteins span the width of cell membranes. Four types of transmembrane proteins are shown in a section of cell membrane. Although these proteins have different specific functions, they all —
stop chemical reactions within the cell
synthesize molecules that signal other cells
help the cell interact with its external environment
remove large waste particles from the cytoplasm of the cell
