Semester 2 Bio Review

Front

The Y axis represents the ____________ variable.

Back

Dependent variable.

Front

Which structures are found in organisms that came from a common ancestor?

Back

Homologous structures.

Front

What do all of these organisms have in common?

Back

Universal genetic code, components that make up the genetic code, traits determined by genes translated into proteins.

Front

Which best describes a cladogram?

Back

A diagram that shows how living species are related and descended from a common ancestor.

Front

Which organelle is the site where amino acids are synthesized into proteins?

Back

Ribosome.

Front

What is the function of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

Define homologous structures with an example.

Back

Homologous structures are body parts that share a common ancestry, such as the forelimbs of humans and bats.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes translate mRNA into amino acid sequences to form proteins.

Front

Explain the concept of natural selection.

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the significance of the universal genetic code?

Back

The universal genetic code allows for the translation of genetic information across different species.
