cells→tissues→organs→organ systems
tissues→organ systems→cells→organs
cells→organs→organ systems→tissues
organ systems→organs→cells→tissues

1. which of the following processes is defined as the net movement of particles from a region of high concentration to a region of low concentration along a concentration gradient?

active transport
evaporation
osmosis
diffusion

Explanation:

For question 10:

• Cells are the basic unit of life.
• Similar cells group together to form tissues.
• Different tissues combine to form organs.
• Organs work together to form organ systems.

For question 11:

• Active transport requires energy and moves particles against the concentration gradient.
• Evaporation is the change of a liquid to a gas.
• Osmosis is the movement of water across a semi - permeable membrane.
• Diffusion is the net movement of particles from a region of high concentration to a region of low concentration along a concentration gradient.

Answer:

1. cells → tissues → organs → organ systems
2. diffusion
