Biology Semester 1 Exam Review: Questions Only

Front

How do viruses cause disease?

Back

Viruses cause disease by replicating inside the cell and then lysing (breaking open) the cell.

Front

What plant response helps maximize and retain water during a drought?

Back

Decreasing stem and leaf growth while increasing root growth helps a plant maximize and retain water during a drought.

Front

How are minerals transported within a plant?

Back

Minerals are transported from the xylem to the phloem in the roots.

Front

In which phase of the cell cycle is DNA replicated?

Back

DNA is replicated during the S phase of the cell cycle.

Front

What property is found only in cancer cells?

Back

Unregulated cell division is a property found only in cancer cells.

Front

What is the function of the xylem in plants?

Back

The xylem transports water and minerals from the roots to the rest of the plant.

Front

What is the role of the phloem in plants?

Back

The phloem transports carbohydrates and nutrients produced by photosynthesis from the leaves to other parts of the plant.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is significant because it is when DNA replication occurs, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What are stem cells?

Back

Stem cells are undifferentiated cells that have the potential to develop into various cell types in the body.
