Biology Final Exam Review

Front

What is the definition of a hypotonic solution?

Back

A solution where the concentration of solutes is lower outside the cell than inside, causing water to enter the cell.

Front

What is the definition of a hypertonic solution?

Back

A solution where the concentration of solutes is higher outside the cell than inside, causing water to leave the cell.

Front

What is the definition of an isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is the largest taxonomic rank?

Back

Domain.

Front

What is the mode of inheritance for traits linked to sex chromosomes?

Back

Sex Linked.

Front

What is the definition of autosomal recessive inheritance?

Back

A mode of inheritance where two copies of a recessive allele must be present for the trait to be expressed.

Front

What is the definition of autosomal dominant inheritance?

Back

A mode of inheritance where only one copy of a dominant allele is needed for the trait to be expressed.

Front

What is a phylogenetic tree?

Back

A diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

What is the significance of the Ring-tailed Lemur and Black spider monkey being closely related?

Back

It indicates that they share a more recent common ancestor compared to other species in the chart.

Front

What is the role of solutes in osmosis?

Back

Solutes affect the movement of water across cell membranes, influencing whether a solution is hypotonic, hypertonic, or isotonic.
