Honors BIO Final Exam Review 2022 Part I

How is the cactus in Figure 25–2 adapted to soak up rare rainfall quickly?

• It has thin, sharp spines.

• It has stems that shrivel when it rains.

• It has wide stems that catch rainwater.

• It has an extensive shallow root system.

What is the phenomenon that is causing the bean seedling to bend towards the light as shown in the figure below?

• gravitropism

• rapid response

• phototropism

• thigmotropism

What is lost to the environment at each of the trophic levels in the ecosystem depicted above?

• nutrients from the soil

• living space for the organisms

• food sources

• heat

What three body systems are involved in this reaction shown in the diagram?

• integumentary, nervous and muscular

• skeletal, nervous, and circulatory

• integumentary, skeletal, and muscular

• integumentary, excretory, and muscular

An endotherm is an animal that

• has a low rate of metabolism.

• can generate its own body heat.

• stores large amounts of food in its stomach.

• can see color very well.

Which system coordinates the body’s response to changes in its internal and external environment?

• lymphatic system

• nervous system

• excretory system

• reproductive system

The diagram below represents a virus with its surface proteins. The other diagrams show various animal cells with receptor proteins. Which of the following cells is most likely affected by this virus?

• 
• 
• 
• 

What is the most common threat to a host organism posed by an invading virus?

• production of viral fluids in the bloodstream

• fermentation of acids in the digestive system

• destruction of cells by viral reproduction

• stimulation of muscle tone in the heart

Which of the labeled structures in the picture above are a part of the male reproductive system?

• anther

• stigma

• style

• ovary

Using Figure 4, which of the following best describes the interaction that occurs between a plant’s reproductive parts during self-fertilization?

• Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches the filament, where the sperm fertilizes the egg.

• Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.

• Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary, where the sperm fertilizes the egg.

• Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.
