<u>Answer:</u>
<em>Hydrogen and ozone are both examples of trace gases.
</em>
<u>Explanation:</u>
Trace gases are present in minor quantities in the <em>earth’s atmosphere and all the gases except nitrogen, oxygen and argon </em>which make up the major portion of earth’s atmosphere are considered trace gases.
The respective percentages of nitrogen, oxygen and argon in the atmosphere are<em> 78.1%, 20.9% and 0.934%.</em> The process that produce trace gases is called source and the process that removes trace gas from the <em>atmosphere is called sink.
</em>
<em>Some other examples of trace gases are carbon dioxide, neon, helium etc.
</em>
The answer is C, serve a different function.
In multicellular organisms, same types of cells makes up a tissue, and tissue makes up organs, then eventually organs work together as an organ system.
For example in humans, stomach cells makes up the stomach tissues, and stomach tissues makes up the stomach. stomach can help digest food and mix food molecules together. But in opposition, red blood cells is present in the blood tissue, however, their function is not to digest food, but is to transport oxygen.
Therefore, we can see that different cells serve a different function.
Answer:
go through a metamorphosis
Explanation:
METAMORPHOSIS is the change in the form and often habits of an animal after the embryonic stage during normal development.
For Example: the transformation of a caterpillar into a butterfly, OR a tadpole into a frog.
Note that the other options given are WRONG because they are characteristics or features of either of them, NOT both.
C6H12O6 + O2 -> CO2 + H2O + ATP.
This would be the summarized equation for cellular respiration.
A control group is kept the same to determine whether or not what you did for an experiment on the experimental group was actually caused by the experiment performed, and not other environmental changes. By keeping the same climate, environments, nourishment, etc. on a control group and experimental group, but only performing the experiment on the experimental group, you can prove your experiment actually works.
