The steps of the DNA ladder are the nitrogenous base pairs.

Front

What are homologous structures?

Back

Homologous structures are body parts of organisms that are the same in structure and position but different in function.

Pollen are small grains that contain a plant's male reproductive cells.

Front

What is the function of phloem in plants?

Back

Front

What is the role of the stamen in flowering plants?

Back

The stamen is the male reproductive part of a flower, producing pollen.

Front

What are analogous structures?

Back

Analogous structures are body parts that have similar functions but different structures and evolutionary origins.

Front

What is a vestigial structure?

Back

A vestigial structure is a body part that has lost its original function through evolution.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is important for a population's ability to adapt to changing environments.

Front

What is the difference between xylem and phloem?

Back

Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports food.
