What is a cladogram?

Back

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

Front

What does it mean for two organisms to be closely related?

Back

Two organisms are considered closely related if they share a recent common ancestor, indicating they have more similar genetic material.

Front

What is the significance of amino acid sequences in determining relatedness among organisms?

Back

Amino acid sequences can reveal evolutionary relationships; organisms with more similar sequences are likely to be more closely related.

Front

What is the primary purpose of courtship behaviors in animals?

Back

The primary purpose of courtship behaviors, such as dancing or singing, is to attract mates for reproduction.

Front

What happens to plant cells when placed in a hypertonic solution?

Back

Plant cells will shrink because water moves out of them to balance the concentration of solutes outside the cell.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell; they generate ATP through cellular respiration, providing energy for cellular activities.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, leading to the movement of water out of cells placed in it.
