What are producers?
This organelle controls the activities of the cell and contains DNA.
What is the nucleus?
This body system absorbs nutrients from food.
What is the digestive system?

What is cell → tissue → organ → organ system → organism?
A change in a DNA sequence is called a ______.
What is a mutation?
Over many generations, most insects in a population become green instead of brown because predators see brown insects more easily. What process caused this change?
What is natural selection?
A hawk eats a snake, and the snake eats a mouse. If the mouse population decreases, explain one likely effect on the hawk population.

What is a cell is living because all of its organelles work together to carry out life processes?
Explain how the respiratory and circulatory systems work together.
What is the respiratory system brings oxygen into the lungs and the circulatory system transports that oxygen throughout the body?
A mutation changes one DNA base in a gene. Explain one possible effect this could have on the organism.
What is it could change the protein that is made, which may change a trait, have no effect, or be harmful/helpful?
Explain why an adaptation must increase survival or reproduction to become more common in a population.
What is organisms with helpful traits are more likely to survive and reproduce, passing those traits to offspring?
Compare how energy moves through an ecosystem to how carbon moves through an ecosystem.
What is energy flows one direction from the sun through organisms and is lost as heat, while carbon cycles between organisms and the environment and is reused?
