Block Schedule Midterm review Biology part 1

Front

What are derived characteristics in biology?

Back

Derived characteristics are traits that are present in an organism but were absent in its last common ancestor. They help in classifying organisms and understanding evolutionary relationships.

Front

What is the correct order of the stages of the cell cycle?

Back

The correct order is: Interphase, Mitosis, Cytokinesis.

Front

What is the primary product of yeast fermentation?

Back

The primary product of yeast fermentation is Carbon Dioxide.

Front

Which organisms lack a nucleus?

Back

Bacteria lack a nucleus; they are prokaryotic organisms.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process by which molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.
