Helium makes very light than hydrogen
<span>Yea as letsreinventlove said, what tissues and how much detail, each of the ones mentioned each has its own sub-categories like loose or dense connective tissue etc. Put down a list of what ya want to know, eg Type; Function; where its found etc and ill happily answer it. Iyts quite a large area</span>
The answer is C because plants use photosynthesis and animals use cellular respiration, so they balance each other out.
<u>Answer</u>: freezing
Freezing is defined as the process through which a substance changes its from from a liquid to a solid. As the liquid lava in the example has lost its thermal energy and thus has hardened, the phase change through which it has undergone is freezing. All liquids with the exception of helium undergo freezing then the average energy of the molecules decreases.
Solidification is another term often used to describe this phenomenon. However, it is much more general and can occur due to other factors such as reactions between different chemicals.
