Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. ... Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.
Explanation:
Polluted water and smog combine to form rain clouds that carry sulphur dioxide and nitrogen oxides which damages forests and vegetation, especially in eastern Europe.
- The deep orange-red gas nitrogen dioxide and the smoke-like particles that accompany it are what give smog its colour. In this demonstration, nitrogen dioxide is created by an electric discharge in the air and turns into acid rain when it is sprayed with water mist.
- Acid rain's primary ingredient is sulfuric acid, which is created when sulphur dioxide reacts with water, air, and other gases. Deforestation can result from acid rain. waterways become more acidic, harming aquatic life.
- High quantities of nitrogen dioxide can damage leaves, slow down growth, or lower crop yields in vegetation. Nitrogen dioxide can react with surfaces, fade and discolour furniture and fabrics, and diminish visibility.

You have to put a lid on petri dishes in order to ensure that no outside contaminants get inside the dish.
Answer:
It can, but each material has a different amount of heat it needs in order to change it’s form.
Explanation:
For example, If you heat water, it will go from the liquid stage to the gaseous stage. It will turn into vapour. So it is changing the form of said material.
This change is mainly due to the breakdown of molecules and chains which enable reactions to happen when heat is applied, since it changes those bonds between molecules.
