• growth

• energy use

• organization

• homeostasis

NGSS.HS-LS1-3

Which example is an activity that a fish most likely uses to maintain homeostasis within its body?

• using camouflage to avoid predators

• feeding at night to regulate body temperature

• moving to deeper water to regulate metabolic wastes

• exchanging gases through its gills to regulate oxygen levels

Which action is prevented by the plasma membrane?

• the flow of light into or out of the cell

• the flow of oxygen into or out of the cell

• unlimited flow of heat into or out of the cell

• unlimited flow of water into or out of the cell

Which statement best describes how antibiotics affect cellular homeostasis?

• Antibiotics remove chloroplasts from plant cells to cause starvation.

• Antibiotics interfere with the transport of intracellular and extracellular materials.

• Antibiotics increase the rate of DNA replication in human cells by forming nucleotides.

• Antibiotics decrease the rate of cellular respiration in animal cells by producing oxygen.

Which transport mechanisms require the formation of a vesicle to transport material into or out of a cell?

• diffusion and osmosis

• exocytosis and endocytosis

• exocytosis and calcium pumps

• diffusion and facilitated diffusion

The shivering mechanism in bumblebees often serves the same purpose as it does in mammals. During which condition will the action of shivering most help a bumblebee to maintain homeostasis?

• decrease in available oxygen

• low environmental temperature

• uncontrolled rise in core temperature

• depletion of oxygen in muscle tissues
