Sarah and Ben are looking at a sample of pond water under the microscope. They see tiny moving objects. "These must be alive," said Sarah. "I’m not sure," said Ben. What do you think? Explain using cell theory.
Responses:
A) According to cell theory, this is alive because it has DNA.
B) According to cell theory, it is not alive. It is not moving or responding.
C) According to cell theory, this is alive because it is made of one or more cells.
D) According to cell theory, this is alive because it is using energy to move.
Correct Answer: C) According to cell theory, this is alive because it is made of one or more cells.
Explanation: According to cell theory, all living organisms are made of cells. Even though the pond water organisms are small, they are made of one or more cells. Movement alone is not enough to determine if something is alive; it needs to have cells.

Which of these is the correct relationship between the digestive system and the respiratory system?
A) The digestive system takes in oxygen, while the respiratory system breaks down food.
B) The digestive system absorbs nutrients, while the respiratory system provides oxygen to the blood.
C) The digestive system transports nutrients, while the respiratory system circulates blood.
D) The digestive system removes waste, while the respiratory system provides energy.
Correct Answer: B) The digestive system absorbs nutrients, while the respiratory system provides oxygen to the blood.
Explanation: The digestive system is responsible for breaking down food and absorbing nutrients, while the respiratory system provides oxygen to the blood, which is necessary for the body’s cells to produce energy
In the process of cellular respiration, what is produced as a waste product?
A) Oxygen
B) Glucose
C) Carbon dioxide
D) Water
C) Carbon dioxide

Max and Lily are observing a jar of yeast that was added to warm sugar water. After some time, they notice the mixture is bubbling. They take a sample of the liquid to examine under the microscope. What does this observation tell you about the yeast?
A) Yeast is not alive because it doesn’t move.
B) Yeast is alive because it produces bubbles, which indicates it is using energy.
C) Yeast is alive because it is made up of multiple cells working together.
D) Yeast is alive because it has DNA.
Correct Answer: B) Yeast is alive because it produces bubbles, which indicates it is using energy.
Explanation: The bubbling is a result of yeast undergoing fermentation, a process where it breaks down sugar and produces carbon dioxide gas. This shows that yeast is using energy, which is a sign of life. Yeast is a living organism made of single cells.
What is the primary difference between prokaryotic and eukaryotic cells?
A) Prokaryotic cells have a nucleus, while eukaryotic cells do not
B) Eukaryotic cells are always unicellular, while prokaryotic cells are multicellular
C) Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not
D) Prokaryotic cells have a nucleus, while eukaryotic cells do not
D) Prokaryotic cells have a nucleus, while eukaryotic cells do not

What is the main function of the skeletal system in the human body?
Responses:
A) To control movement and send signals to muscles.
B) To protect vital organs and support the body’s structure.
C) To transport oxygen to the muscles.
D) To produce insulin for energy.
Correct Answer: B) To protect vital organs and support the body’s structure.
Explanation: The skeletal system provides structure and support to the body. It protects vital organs, such as the brain and heart, and works with muscles to enable movement.
What is the process by which plants make their own food using sunlight?
A) Digestion
B) Germination
C) Photosynthesis
D) Respiration
C) Photosynthesis

Which organelle is responsible for making food in plant cells, and why is this important for plants?
A) Mitochondria, because they provide energy for the plant’s growth.
B) Chloroplasts, because they capture sunlight to make food through photosynthesis.
C) Ribosomes, because they make proteins for the plant.
D) Nucleus, because it controls the plant's growth and reproduction.
Correct Answer: B) Chloroplasts, because they capture sunlight to make food through photosynthesis.
Explanation: Chloroplasts are the organelles in plant cells that contain chlorophyll and conduct photosynthesis. Photosynthesis is the process by which plants make their own food using sunlight, carbon dioxide, and water, and it is essential for the plant’s survival.
What is the function of the DNA in a cell?
A) To provide energy
B) To store genetic information
C) To control the movement of molecules
D) To produce proteins
B) To store genetic information

Clara has a cough and her doctor believes she might have a bacterial infection. To confirm, the doctor sends a sample of Clara’s throat swab to the lab. What is the doctor looking for in Clara's sample?
A) A virus that causes the flu.
B) Bacteria that can cause a throat infection.
C) Fungus that causes a skin rash.
D) A protozoan that causes stomach illness.
Correct Answer: B) Bacteria that can cause a throat infection.
Explanation: Bacterial infections, such as strep throat, are caused by specific bacteria. The doctor would culture the sample to check for the presence of these bacteria to confirm the diagnosis.
What do all animals need to survive?
A) Light
B) Soil
C) Oxygen
D) Saltwater
C) Oxygen
In a Punnett square, what do the letters inside the grid represent?
A) The phenotype of the offspring
B) The possible genotypes of the offspring
C) The alleles of the parent organisms
D) The number of chromosomes
B) The possible genotypes of the offspring
Imagine a plant wilts after being left in the sun without enough water. Which part of the plant cell is most responsible for the wilting, and why?
A) The chloroplasts, because they stop producing food without sunlight.
B) The vacuole, because it loses water and causes the cell to shrink.
C) The nucleus, because it stops the plant from growing.
D) The plasma membrane, because it prevents water from entering the cell.
Correct Answer: B) The vacuole, because it loses water and causes the cell to shrink.
Explanation: The vacuole in plant cells holds water. When a plant doesn’t have enough water, the vacuole loses water, causing the cell to shrink and the plant to wilt. The vacuole’s role in maintaining turgor pressure is crucial for keeping the plant upright.
What is the main function of the digestive system in humans?
A) To circulate blood throughout the body
B) To protect the body from pathogens
C) To break down food and absorb nutrients
D) To transport oxygen to cells
C) To break down food and absorb nutrients
Which of the following is true about asexual reproduction?
A) It requires two parent organisms
B) It produces genetically identical offspring

D) It is common in many single-celled organisms
D) It is common in many single-celled organisms
Which of the following systems is responsible for transporting oxygen and nutrients throughout the body?
A) The digestive system.
B) The respiratory system.
C) The circulatory system.
D) The nervous system
Correct Answer: C) The circulatory system.

Which of the following would be considered a sign of a viral infection rather than a bacterial infection?
Responses:
A) A sore throat caused by bacteria that can be treated with antibiotics.
B) A cold caused by a virus that cannot be treated with antibiotics.
C) A skin infection caused by bacteria that can be treated with antibiotics.
D) A stomach virus that can be treated with antibiotics.
Correct Answer: B) A cold caused by a virus that cannot be treated with antibiotics.
Explanation: The common cold is caused by a virus, and viruses cannot be treated with antibiotics. Antibiotics are only effective against bacterial infections, not viral infections like the cold or flu.
