Which statements are supported by the image above? (Choose all that apply.)

• Chemical energy in glucose is transferred to ATP to power cellular functions. 

• some of the energy stored in organic molecules is lost as heat energy. 

• heat energy is used trapped by water during photosynthesis. 

• Solar energy is captured by chloroplasts. 

• energy from the sun is stored in oxygen gas

Which means of particle transport is shown in the image below?

• Diffusion

• Facilitated diffusion

• Osmosis

• Active transport

The removal of mitochondria from a typical animal cell would have an immediate effect on the cell’s production of

• DNA

• oxygen

• ATP

• glucose

Within a specific kind of tissue, there are different types of cells. In bone tissue, there are four different cell types, as shown in the picture. Since the four types of cells contain the same genetic instructions, how is it possible for them to have different shapes and carry out different functions?

• Each cell type has the ability to remove unnecessary DNA sequences.

• Different parts of the genetic code may be used in each of the cell types.

• Different gene mutations take place within each cell type.

• Each cell type is the result of different methods of cell division.

What is the most likely reason for the variation in the dissolved oxygen levels in the pond over the 24-hour period?

• The increased light during the day decreases the oxygen produced by photosynthesis.

• Photosynthesis produces more oxygen during the day than is used by respiration.

• Respiration is reduced at night, so the oxygen produced by photosynthesis increases.

• More producers are active at night, so the dissolved oxygen increases.

The diagram illustrates the movement of molecules across an artifi cial membrane in a U-shaped glass tube. A 1% starch solution was poured into the left side of the tube, and distilled water was placed in the right side of the tube.

Explain why the liquid level on the left side changed over the 20-minute period

Which statement best describes the interactions between the structures found within a single-celled organism?

• They allow the organism to maintain homeostasis

• They prevent homeostasis from damaging the cell.

• They must act independently of each other and prevent homeostasis.

• They carry out the same life process in order to maintain homeostasis.

The process of differentiation is best described as the

• production of a genetically identical copy of an organism

• change in shape of a protein due to high temperatures

• process by which cells specialize and develop into a specific type of cell

• process in which genes are made and transferred into other organisms

• Ribosomes

• Nucleus

• Mitochondria

• Vacuole

Which organelle makes digestive enzymes for the lysosome?

• ribosome

• mitochondria

• Golgi Body
