The Venus fly trap is a plant that has a unique system by which it traps and breaks down its prey. Unsuspecting insects land on the leaf and touch tiny hairs located on the leaf, triggering the leaf to close around the prey

The substance responsible for breaking down the Venus fly trap’s prey most likely contains

• chlorophyll molecules

• glucose mlecules

• hormone molecules

• enzyme molecule

Certain seaweeds contain a greater concentration of iodine inside their cells than there is in the seawater surrounding them. The energy required to maintain this concentration difference is most closely associated with the action of

• ribosomes

• vacuoles

• mitochondria

• nuclei

An amoeba is a single-celled organism. It uses its cell membrane to obtain food from its environment, digests the food with the help of organelles called lysosomes, and uses other organelles to process the digested food. From this, we can best infer that

• amoebas are capable of digesting any type of food molecule

• single-celled organisms are as complex as multicellular organisms

• all single-celled organisms have lysosomes to digest food

• structures in amoebas have functions similar to organs in multicellular organisms

The diagram represents a portion of a cell membrane.

The arrow indicates that the cell membrane is carrying out the process of

• respiration

• diffusion

• cell recognition

• active transport

The two diagrams represent a sugar molecule and a fat molecule that are used by living organisms.

Which statement best describes these two molecules?

• Sugar molecules are inorganic and fat molecules are organic.

• Sugar molecules are organic and fat molecules are inorganic.

• Energy for life processes can be stored within the chemical bonds of both molecules

• Energy for life processes can be stored within the chemical bonds of sugar molecules, only
