Biology 1 End-Of-Course Assessment FLDOE questions

Front

What is the scientific theory of evolution?

Back

The scientific theory of evolution explains how species change over time through processes such as natural selection and common ancestry.

Front

How do scientists use skeletal comparisons to support evolution?

Back

Comparing skeletons of different species can show possible common ancestry, indicating that they may have evolved from a shared ancestor.

Front

What is mitosis?

Back

Mitosis is a type of cell division that results in two daughter cells that are identical to the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells.

Front

What is the role of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, essential for photosynthesis and transpiration.

Front

What is hemophilia?

Back

Hemophilia is a sex-linked, recessive genetic disorder that affects the blood's ability to clot.

Front

What does it mean for a trait to be sex-linked?

Back

A sex-linked trait is one that is associated with a gene located on a sex chromosome, often affecting males and females differently.

Front

What is the probability of a son having hemophilia if his mother is a carrier?

Back

There is a 50% chance that a son will inherit hemophilia if his mother is a carrier.

Front

Why are invasive species a concern for ecosystems?

Back

Invasive species can disrupt local ecosystems by preying on native species, competing for resources, and altering habitats.

Front

What is the significance of guard cells in plants?

Back

Guard cells regulate the opening and closing of stomata, controlling gas exchange and water loss in plants.
