Many cellular processes are performed by cells. Which of the following is the best reason this cell is going through the process shown?

How would a disease that damages the mitochondria most directly affect the functioning of cells?

• protein making would be stopped

• waste materials would remain trapped in the cell

The circulatory and digestive systems interact with each other to help maintain homeostasis in the human body. Which pair of actions describes how these two systems work together to maintain homeostasis?

• taking in oxygen and transporting it to all the cells

• moving nutrients and fighting infections in the body

• removing wastes and excreting them out of the body

• providing nutrients and transporting them to the cells

What is a similarity between the respiratory and excretory systems?

• They both break down food

• They both remove waste from the body

• They both exchange gases within the body

• They both transport nutrients throughout the body

The human body has several major systems. Most body systems have multiple functions. Which of the following is NOT a major function of the musculoskeletal system?

• turning food into energy

• helping the lungs take in air

• helping the stomach digest food

• moving the bones of the skeleton

Which of these combinations identifies the appropriate labels in the order as shown in the diagram (1, 2, 3)?

• chromosome, DNA, gene

• chromosome, gene, DNA

• DNA, chromosome, gene

• DNA, gene, chromosome

Each cell in an organism contains a set of hereditary information that gets passed from one generation to the next. The genes in all organisms contain instructions needed to make offspring. Which statement describes heredity in animals?

• Offspring show recessive traits only

• Offspring receive genetic traits from a single parent only

• Offspring receive genes with traits that are always physically observable

• Offspring receive genes from each parent, which contribute to the traits in the offspring
