The mouth, stomach, small intestine, and large intestine are organs that work together to perform the specific function of food digestion and absorption in organisms. Which of the following describes the level of biological organization described above?

• cell

• organelle

• organ system

• organ

You accidentally place your hand on a hot stove. The nerve cells in your hand respond to the pain, the stimulus, resulting from the heat. The nerve cells would relay this information to which of the following?

• stimulus

• effector

• receptor

• control center

When a muscle cell is stimulated, calcium is released into the muscle fiber. This calcium binds to proteins that start the muscle contraction process. The initial release of calcium triggers more calcium release, which amplifies the contraction. This feedback loop continues until the muscle contraction is fully achieved. Which of the following best describes the scenario above?

• metabolism

• adaptation

• positive feedback loop

• negative feedback loop

A specific type of MRI, or magnetic resonance imaging, looks at the brain in 24 vertical sections, starting from the right side of the brain and moving to the left side of the brain.

Which of the following planes of symmetry would split the human brain into left and right vertical sections?

• saggital

• spinal

• transverse
