An animal’s heart rate and breathing rate decrease during hibernation. How do these changes help the animal survive?, They reduce the animal’s energy needs when food is limited., They allow the animal to stop all cellular activities., They increase the amount of energy used by its cells., They allow its cells to make glucose using sunlight., Which observation provides the strongest evidence that an organism is maintaining homeostasis?, A person’s hair grows longer over several months., A person inherits eye color from their parents., A person breaks a bone after falling., A person sweats when body temperature rises, helping the body cool., White blood cells help fight infections. If an animal produces fewer white blood cells, which outcome is most likely?, Its blood will carry more glucose., Its ability to fight infections may decrease., Its digestive system will stop absorbing water., Its cells will no longer need oxygen., Which substances are used in cellular respiration to release energy from food?, Carbon dioxide and water, Oxygen and carbon dioxide, Glucose and oxygen, Glucose and water, Which statement correctly describes the role of ATP in cells?, ATP supplies usable energy for cell activities., ATP stores the cell’s inherited information., ATP controls which substances enter the cell., ATP captures sunlight during photosynthesis., A muscle cell needs large amounts of ATP to contract repeatedly. Which organelle would you expect to be especially abundant in this cell?, Chloroplast, Cell wall, Nucleus, Mitochondrion, Which statement correctly compares photosynthesis and cellular respiration?, Both processes require sunlight to occur., Photosynthesis stores energy in glucose, and respiration transfers energy from glucose to ATP., Photosynthesis occurs only in animals, and respiration occurs only in plants., Both processes use oxygen to break down glucose., A single-celled organism moves away from a harmful chemical. Which characteristic of life does this demonstrate?, Passing traits to offspring, Growing and developing, Responding to a stimulus, Reproducing, Which cell structure helps maintain homeostasis by controlling what enters and leaves the cell?, Ribosome, Nucleus, Cell membrane, Cell wall, Oxygen is more concentrated outside a cell than inside it. Oxygen moves directly through the membrane into the cell without using ATP. This is an example of, Active transport, Protein synthesis, Osmosis, Diffusion, An animal cell is placed in a solution with a higher concentration of dissolved salt than the cell’s cytoplasm. What will most likely happen?, Salt will change into water inside the cell., Water will leave the cell, causing it to shrink., The cell will use photosynthesis to remove the salt., They allow its cells to make glucose using sunlight., A cell uses ATP to move a substance from an area of lower concentration to an area of higher concentration. Which process is occurring?, Osmosis, Simple diffusion, Active transport, Passive transport, An enzyme works well at normal body temperature but stops working after exposure to very high temperatures. What is the best explanation?, The enzyme’s active site changed shape, preventing the substrate from fitting properly., The enzyme used up all its stored energy., The enzyme changed into the substrate., The enzyme began producing a different type of cell.
