Which of the following is an example of osmosis?

• Water moves into the root cells of a tree
• Carbon dioxide molecules move into a leaf cell
• Oxygen molecules move into a lung cell
• Perfume molecules spread throughout an empty room

Which of the following is required for active transport to occur across a cell membrane?

• ATP
• water
• oxygen
• helium

A dentist told their patient to gargle with salt water to reduce the swelling of their gums.  Why did the dentist advise their patient to gargle with salt water?

• More water would move into the patient's gums and increase swelling
• Water would move out of the gums toward the salt to reduce swelling
• Salt would immediately enter the gums and absorb the extra water inside the gum cells
• The water and salt would chemically react to create an antiviral chemical in the gums

An athlete begins sweating while running a marathon.  The sweating cools his body down to maintain a body temperature of 98 degrees.  This is an example of which of the following?

• homeostasis
• photosynthesis
• adaptation
• organization

• Phospholipids & Proteins
• DNA & Proteins
• DNA & Sugar
• Carbohydrates Only

Which process moves molecules AGAINST a concentration gradient?

• diffusion
• osmosis
• active transport
• protein synthesis

If energy is NOT needed to move materials in or out of a cell, what process is most likely happening?

• Active Transport
• Passive Transport
• Respiration
• Vacuole
