During osmosis

• water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built

Osmosis is the movement of _____ across a membrane.

• food

• energy

• oxygen

• water

why is osmoregulation so important?

• water gives support and is an important transport medium

• it hydrates the body

• it regulates hormone secretion

Maintaining stable internal conditions despite changes in the external environment

• Homeostasis

• Metabolism

• Protein Synthesis

• Adaptation

Nemo and other ocean dwelling fish cannot survive in freshwater because......

• freshwater is hypertonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypotonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypertonic to Nemo's cells and will result in water entering them causing the cells to swell and burst

• freshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burst
