Salutations!
A group of cells working together are called tissues. Organisms are made up of this structure. Cells are the smallest unit of life. A group of tissues working together is called organ. A group of organs working together is called organ system. An organ system working together makes up an organism.
Hope I helped (:
Have a great day!
The molecule that can MOST easily pass through the plasma membrane without assistance is carbon dioxide (CO2). Diffusion is a type of passive transport that occurs when molecules move in favor of a concentration gradient.
During diffusion, molecules move high concentration to a region of low concentration.
Oxygen (O2) and carbon dioxide (CO2) are non-polar gasses that move across cell membranes by a process called simple diffusion.
Simple diffusion is a type of passive transport that does not require energy to move substances across cell membranes.

Answer:
The correct answer is as showed in the Explanation
Explanation:
Seismic waves are waves of energy that are produced due to Earth's layers movement, such as the ones occurring during earthquakes. Scientists developed an early warning system to determine when an earthquake is going to take place by analyzing the behavior of two types of waves: P waves and S waves. P waves are the ones that travel faster and are produced first, they travel in an exact opposite direct of where the earthquake is produced. On the other hand, s waves or secondary waves are slower and travel in a perpendicular way. Scientist detect when these waves are generated in specialized centers.

Equilibrium is a state in which opposing forces or actions are balanced so that one is not stronger or greater than the other Supply and demand were in equilibrium
To proceed scientifically, you could measure several properties of the unknown liquid and compare them with the properties of known substances. You might observe and measure such properties as color, odor, texture, density, boiling point, and freezing point.
